a902f69aea Update A2-Zippy example
The ZipChip GS register definitions can take advantage of the new
I/O direction feature.  Pulling them out into a .sym65 makes sense.

cd23580cc5 Add junk/align directives
Sometimes there's a bunch of junk in the binary that isn't used for
anything.  Often it's there to make things line up at the start of
a page boundary.

This adds a ".junk" directive that tells the disassembler that it
can safely disregard the contents of a region.  If the region ends
on a power-of-two boundary, an alignment value can be specified.

The assembly source generators will output an alignment directive
when possible, a .fill directive when appropriate, and a .dense
directive when all else fails.  Because we're required to regenerate
the original data file, it's not always possible to avoid generating
a hex dump.

716dce5f28 Pass operand to extension script JSR/JSL handlers
Sort of silly to have every handler immediately pull the operand out
of the file data.  (This is arguably less efficient, since we now
have to serialize the argument across the AppDomain boundary, but
we should be okay spending a few extra nanoseconds here.)

c8dfa94ce2 Change find-previous hotkey to Shift+F3

around by switching the control to single-select mode when changing

9c3422623d External symbol I/O direction and address mask, part 1
Memory-mapped I/O locations can have different behavior when read
vs. written.  This is part 1 of a change to allow two different
symbols to represent the same address, based on I/O direction.

This also adds a set of address masks for systems like the Atari
2600 that map hardware addresses to multiple locations.

This change updates the data structures, .sym65 file reader,
project serialization, and DefSymbol editor.

fac2d6a51f Invoke extension scripts when labels they care about change
We were failing to update properly when a label changed if the label
was one that a plugin cared about.  The problem is that a label
add/remove operation skips the code analysis, and a label edit skips
everything but the display update.  Plugins only run during the code
analysis pass, so changes weren't being reflected in the display
list until something caused it to refresh.

The solution is to ask the plugin if the label being changed is one
that it cares about.  This allows the plugin to use the same
wildcard-match logic that it uses elsewhere.

For efficiency, and to reduce clutter in plugins that don't care
about symbols, a new interface class has been created to handle the
"here are the symbols" call and the "do you care about this label"
call.

The program in Examples/Scripts has been updated to show a very
simple single-call plugin and a slightly more complex multi-call
plugin.

3702448780 Correctly handle a label update edge case
Test case:
 1. create a label FOO
   (can be referenced or unreferenced)
 2. add a platform symbol file that also defines FOO
   (the platform symbol will be masked by the user label)
 3. rename FOO to BAR
   (platform symbol should appear)
 4. hit "undo"
   (platform symbol should disappear)
 5. delete label FOO
   (platform symbol should appear)
 6. hit "undo"
   (platform symbol should disappear)

This will fail to update the display list properly, and/or crash
when we try to add FOO to a symbol table that already has a
symbol with that label.

The problem is the optimization that tries to avoid running the
data analysis pass if we're just renaming a user label.  We need to
check to see if the rename overlaps with project/platform symbols,
because we need to update the active def symbol set in that case.

To avoid the crash, we just need to use table[key]=value syntax
instead of table.Add(key,value).

df2f3803f4 SourceGen After Dark
Most of SourceGen uses standard WPF controls, which get their default
style from the system theme.  The main disassembly list uses a
custom style, and always looks like the Windows default theme.

Some people greatly prefer white text on a black background, so we
now provide a way to get that.  This also requires muting the colors
used for Notes, since those were chosen to contrast with black text.

This does not affect anything other than the ListView used for
code, because everything else can be set through the Windows
"personalization" interface.  We might want to change the way the
Notes window looks though, to avoid having glowing bookmarks on
the side.

d8604294bb Change how the "quick set" settings work
The last two tabs in the Edit App Settings dialog have "quick set"
buttons configure all fields for a particular assembler, or reset
them to default values.  The previous UI was a little annoying,
because you had to pick something from the combo box and then hit
"set" to push the change.  It was also confusing, because if you
came back later the combo box was just set to the first entry, not
the thing you picked last.

Now, picking an entry from the combo box immediately updates all
fields.  The combo box selection is set to reflect the actual
contents (so if you set everything just right, the combo box will
change to a specific assembler).  If nothing matches, a special
entry labeled "Custom" is selected.

Also, rearranged the tutorial sections in the manual so the
address table formatting comes last, and appears in the local TOC.

475c31b886 Tweak navigation
If you select a local variable, double-click on a reference entry,
and then hit "back", you aren't taken back to the correct place in
the local variable table.  This is annoying if you're trying to
explore how a local variable is used.

The NavStack Location object now has a "line delta" that can be
applied to position the selection correctly.  This isn't stable
across undo/redo, but it solves the common cases.

This makes LineListGen's "Top" class redundant, so uses of that have
been replaced with Location.

3a67c14247 Add "find previous"
The Find box now has forward/backward radio buttons.  Find Next
searches forward, and Find Previous searches backward, regardless
of the direction of the initial search.

The standard key sequence for "find previous" is Shift+F3.  The WPF
ListView has some weird logic that does something like: if you hit
a key, and the selection changes, and the shift key was held down,
then you must have meant to select a range.  So Shift+F3 often (but
not always) selects a range.  I think this might be fixable if I can
figure out how ListView keeps track of the current keyboard
navigation position (which is not the same as the selection).  For
now I'm working around the problem by using Ctrl+F3 to search.
Yay WPF.

dfd5bcab1b Optionally treat BRKs as two-byte instructions
Early data sheets listed BRK as one byte, but RTI after a BRK skips
the following byte, effectively making BRK a 2-byte instruction.
Sometimes, such as when diassembling Apple /// SOS code, it's handy
to treat it that way explicitly.

This change makes two-byte BRKs optional, controlled by a checkbox
in the project settings.  In the system definitions it defaults to
true for Apple ///, false for all others.

ACME doesn't allow BRK to have an arg, and cc65 only allows it for
65816 code (?), so it's emitted as a hex blob for those assemblers.
Anyone wishing to target those assemblers should stick to 1-byte mode.

Extension scripts have to switch between formatting one byte of
inline data and formatting an instruction with a one-byte operand.
A helper function has been added to the plugin Util class.

To get some regression test coverage, 2022-extension-scripts has
been configured to use two-byte BRK.

Also, added/corrected some SOS constants.

See also issue #44.

b8e11215fa Add separate button for adding symbols+scripts from project
The "add platform symbol file" and "add extension script" buttons
create a file dialog with the initial directory set to the
RuntimeData directory inside the SourceGen installation directory.
This is great if you're trying to add a file from the platform
definitions, but annoying if you're trying to add it from the
project directory.

It's really convenient to not have to hunt around though, so now
there are two buttons: one for platform, one for project.  The
latter is disabled if the project is new and hasn't been saved yet.

e1a9100a8f Fully style the code list view
We were changing the control template for lines with long comments
and notes, matching the default Win10 style.  This got ugly when a
non-default theme was being used, particularly "dark" themes,
because the long-comment lines looked significantly different from
everything else.

We now fully specify the style for the ListView and ListViewItems,
which means everybody's main window now looks like the default Win10
style.  Which is unfortunate, but significantly easier than creating
a full set of theme-specific styles.

We now specify black text for highlighted address/label fields,
because they otherwise become illegible when we apply our background
highlight color.  In the Notes window, we set the background of
un-highlighted entries to white, so that we can always read it with
black text.

Addresses issue #50.

245e0bd9f3 Make address translation available to extension scripts

8c87ce3004 Check formatted string structure at load time
If we have a bug, or somebody edits the project file manually, we
can end up with a very wrong string, such as a null-terminated
string that isn't, or a DCI string that has a mix of high and low
ASCII from start to finish.  We now check all incoming strings for
validity, and discard any that fail the test.  The verification
code is shared with the extension script inline data formatter.

Also, added a comment to an F8-ROM symbol I stumbled over.

28eafef27c Expand the set of things SetInlineDataFormat accepts
Extension scripts (a/k/a "plugins") can now apply any data format
supported by FormatDescriptor to inline data.  In particular, it can
now handle variable-length inline strings.  The code analyzer
verifies the string structure (e.g. null-terminated strings have
exactly one null byte, at the very end).

Added PluginException to carry an exception back to the plugin code,
for occasions when they're doing something so wrong that we just
want to smack them.

Added test 2022-extension-scripts to exercise the feature.

3c3209b67f Expand set of symbols available to plugins
We were providing platform symbols to plugins through the PlatSym
list, which allowed them to find constants and well-known addresses.
We now pass all project symbols and user labels in as well.  The
name "PlatSym" is no longer accurate, so the class has been renamed.

Also, added a bunch of things to the problem list viewer, and
added some more info to the Info panel.

Also, added a minor test to 2011-hinting that does not affect the

37855c8f8e Allow explicit widths in project/platform symbols, part 4 (of 4)
Handle situation where a symbol wraps around a bank.  Updated
2021-external-symbols for that, and to test the behavior when file
data and an external symbol overlap.

The bank-wrap test turned up a bug in Merlin 32.  A workaround has
been added.

0d9814d993 Allow explicit widths in project/platform symbols, part 3
Implement multi-byte project/platform symbols by filling out a table
of addresses.  Each symbol is "painted" into the table, replacing
an existing entry if the new entry has higher priority.  This allows
us to handle overlapping entries, giving boosted priority to platform
symbols that are defined in .sym65 files loaded later.

The bounds on project/platform symbols are now rigidly defined.  If
the "nearby" feature is enabled, references to SYM-1 will be picked
up, but we won't go hunting for SYM+1 unless the symbol is at least
two bytes wide.

The cost of adding a symbol to the symbol table is about the same,
but we don't have a quick way to remove a symbol.

Previously, if two platform symbols had the same value, the symbol
with the alphabetically lowest label would win.  Now, the symbol
defined in the most-recently-loaded file wins.  (If you define two
symbols with the same value in the same file, it's still resolved
alphabetically.)  This allows the user to pick the winner by
arranging the load order of the platform symbol files.

Platform symbols now keep a reference to the file ident of the
symbol file that defined them, so we can show the symbols's source
in the Info panel.

These changes altered the behavior of test 2008-address-changes,
which includes some tests on external addresses that are close to
labeled internal addresses.  The previous behavior essentially
treated user labels as being 3 bytes wide and extending outside the
file bounds, which was mildly convenient on occasion but felt a
little skanky.  (We could do with a way to define external symbols
relative to internal symbols, for things like the source address of
code that gets relocated.)

Also, re-enabled some unit tests.

Also, added a bit of identifying stuff to CrashLog.txt.

14150af004 Allow explicit widths in project/platform symbols, part 2
Added a Width column to the list in the project symbol editor.

Changed the local variable table editor and the project symbol editor
to use DataGrid instead of ListView.  This gets us easy sorting on
arbitrary columns.  The previous code was reloading the display list

which helps keep the list position and selection stable.

2a41d70e04 Allow explicit widths in project/platform symbols, part 1
The ability to give explicit widths to local variables worked out
pretty well, so we're going to try adding the same thing to project
and platform symbols.

The first step is to allow widths to be specified in platform files,
and set with the project symbol editor.  The DefSymbol editor is
also used for local variables, so a bit of dancing is required.
For platform/project symbols the width is optional, and is totally
ignored for constants.  (For variables, constants are used for the
StackRel args, so the width is meaningful and required.)

We also now show the symbol's type (address or constant) and width
in the listing.  This gets really distracting when overused, so we
only show it when the width is explicitly set.  The default width
is 1, which most things will be, so users can make an aesthetic
choice there.  (The place where widths make very little sense is when
the symbol represents a code entry point, rather than a data item.)

The maximum width of a local variable is now 256, but it's not
allowed to overlap with other variables or run of the end of the
direct page.  The maximum width of a platform/project symbol is
65536, with bank-wrap behavior TBD.

The local variable table editor now refers to stack-relative
constants as such, rather than simply "constant", to make it clear
that it's not just defining an 8-bit constant.

Widths have been added to a handful of Apple II platform defs.
