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.

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
output (which is the point).

3172ea0b70 Update Apple II data files
Added symbols for the ProDOS 8 global page, as well as some notes
about screen holes.

Also, if a platform symbol has a tag, show it in the Info panel.

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.

7739f640f5 Minor tweaks
Added a blank line after local variable tables.  Otherwise they
just sort of blend in with the stuff around them.

Put prefixes before the DOS 3.3 platform symbols.

Added a BAS_HBASH entry.  We were getting BAS_HBASL and MON_GBASH
paired up, which looks weird.

Apply a very light tint to the preview section of the Edit Long
Comment dialog, to hint that the window is read-only.

c1056839b1 Changed naming convention in Applesoft/F8-ROM symbol files
I was using the plain names, but when you've got symbols like
READ and WAIT it's too easy to have a conflict and it's not plainly
obvious where something came from.  Now all monitor symbols begin
with MON_, and Applesoft symbols begin with BAS_.

The Amper-fdraw example ended up with a few broken symbol refs,
because it was created before project/platform symbols followed the
"nearby" rules, and was explicitly naming LINNUM and AMPERV.  I
switched the operands to default, and they now auto-format correctly.

I added a few more entries to Applesoft while I was at it.

2828cc8ca7 Apply project/platform symbols to Numeric/Address data operands
A ".dd2 <address>" item would get linked to an internal label, but
references to external addresses weren't doing the appropriate
search through the platform/project symbol list.

This change altered the output of the 2019-local-variables test.
The previous behavior was restored by disabling "nearby" symbol
matching in the project properties.

Updated the "lookup symbol by address" function to ignore local
variables.

Also, minor updates to Applesoft and F8-ROM symbol tables.

0616e4e4a4 Define interfaces for inline call handlers and BRK
Instead of providing no-op CheckJsr/CheckJsl, plugins now declare
which calls they support by defining interfaces on the plugin class.

I added a CheckBrk call for code like Apple /// SOS calls, which
use BRK as an OS call mechanism.  The formatting doesn't work quite
right yet because I've been treating BRK as a two-byte instruction.
Hardly anything else does, and I think it's time I stopped (but not
in this commit).

Note: THIS BREAKS ALL PLUGINS that use the inline JSR/JSL feature,
which is pretty much all of them.

b37d3dba02 Expand reach of external symbol nearby-target test
If PTR is defined as an external symbol, we were automatically
symbol-ifying PTR+1.  Now we also symbolify PTR+2.  This helps with
24-bit pointers on the 65816, and 16-bit "jump vectors", where the
address is preceded by a JMP opcode.

Removed the "AMPERV_" symbol I added to make the tutorial look
right.
