13dca8b78c More tweaks to def sym editing
If you edit an existing symbol, the "is the label unique" test will
always false-positive match itself, so we have to explicitly handle
that case.  Dialogs like Edit Instruction Operand make things a bit
more complicated because they don't flush results to the symbol
table immediately, which means the symbol we pass into the Edit Def
Symbol dialog to edit isn't necessarily the one we need to exclude
from the label uniqueness test.

The dialog was using the initial value as both "original" and
"initial", which caused some issues.  We now pass both values in.

Also, removed some dead code identified by VS.

3a2c4fa6d2 ORG rework, part 4
Reimplemented "set address" dialog as the Address Region Editor.  The
new dialog configures itself differently depending on whether the user
appears to be trying to create, edit, or resize a region.  Each mode
has two options, to allow the user to choose between floating and fixed
end points.

The old dialog would allow you to delete an address override by erasing
the address field.  Now there's an explicit "delete region" button.

Changed the SetAddress undoable change function to use AddressMapEntry
objects.

We now show detailed information on .arstart/.arend in the Info window
when the lines are selected.

PRG files are now created without specifying a region for the first
two bytes, so the load address exists in a NON_ADDR hole.  Fixed a
couple of issues to make that look right.

f4bee76023 Update junk counter
The bottom of the main window shows the total bytes in the project
along with how many are code, data, and junk.  The junk figure wasn't
updating if you changed a data item to junk or vice-versa, because a
simple format change doesn't require reanalyzing the file.

To make the counter "live", we need to tell the updater to refresh the
values whenever a format changes to or from "junk".

49f4017410 Rename "hints" to "analyzer tags"
Variables, types, and comments have been updated to reflect the new
naming scheme.

The project file serialization code is untouched, because the data
is output as serialized enumerated values.  Adding a string conversion
layer didn't seem worthwhile.

No changes in behavior.

f30780a9de Fix Message update when broken symbolic ref is fixed
Renaming a user label doesn't cause a re-analysis, just a display
update, because nothing structural is changing.  However, that's not
quite true when you have a reference to a non-existent label (e.g.
"LDA hoser"), and you rename a label to match (e.g. change "blah"
to "hoser").  The most obvious consequence was that the Message list,
which enumerates the broken symbolic references, was not being
updated.

We now identify broken references during the refactoring rename, and
change the reanalysis mode accordingly.

There is a deeper problem, where undoing the label rename does the
wrong thing with the previously-broken symbolic references (in the
earlier example, it "undoes" them to "blah" rather than back to
"hoser").  I added some notes about that, but it's harder to fix.

Also, clean up some code that was still treating ReanalysisScope as
if it were bit flags.

18e6951f17 Add Data Bank Register management, part 1
On the 65816, 16-bit data access instructions (e.g. LDA abs) are
expanded to 24 bits by merging in the Data Bank Register (B).  The
value of the register is difficult to determine via static analysis,
so we need a way to annotate the disassembly with the correct value.
Without this, the mapping of address to file offset will sometimes
be incorrect.

This change adds the basic data structures and "fixup" function, a
functional but incomplete editor, and source for a new test case.

b4213de4c0 Add "Go to Last Change" feature
Jumps to the first offset associated with the change at the top of
the Undo stack.  We generally jump to the code/data offset, not the
specific line affected.  It's possible to do better (and we do, for
Notes), but probably not worthwhile.

0eeb36f59a Add LocalVariableTable list to project
This involved adding a list to the DisasmProject, creating a new
UndoableChange type, and writing the project file serialization
code.  While doing the latter I realized that the new Width field
was redundant with the FormatDescriptor Length field, and removed it.

I added a placeholder line type, but we're not yet showing the
table in the display list.  (To edit the tables you just have to
know where they are.)
