Also, delineate standard from non-standard.

QWK kludge lines - string literals should not be interpretted in these
strings! Yes, you'll need to cvs-update xpdev/* too.

values (string literals not supported/parsed).
iniPopKey() no longer supportes string literals. Use the new iniPopString() if
you need to pop parsed string-literals from a string list.
All the non-String get/read function no longer bother with parsing string
literals.

Instead of each control function having separate code to parse sequences,
use shared code which splits it into a structure and parses parameters.

This fixes all sorts of ANSI bugs with leading zeros, default values, etc.

Not all sequences have been updated yet, but I'll plug away at this slowly.

Now, instead of a couple sequences having broken parsing, and them all being
broken in different ways, all sequences can be broken in the same way all at
once.

Use C64 palette from CTerm
Switch drawrect to use 32-bit pixels
Put the colour palette index into the screen array, not the attribute palette one
Remove dac_colors from video_stat structure

bitmap_setvideoflags() force a screen redraw.  This fixes the status bar
in SyncTERM after a CSI 32 h / CSI 32 l pair.

no responses were being sent for a couple of different reasons (misplaced break
and erroneous check of strcmp result).

CTerm (and therefore SyncTERM 1.0) required an extra two ignored garbage
bytes in the font data.

ESC ] 104 ESC \ will reset all palette entries.
ESC ] 104;X;Y... ESC \ will reset specified palette entries only.

ie: perl -e 'print "\e]104;1;2\e\\"'
Will reset palette entries 1 and 2.

ESC ] <string> ESC \

Where string is in the format:
rgb:R/G/B
And the values of R, G, and B are one to four hex digits.  For example:
"\e]4;1;rgb:0/0/a8" will reset the blue entry to the default value.

drop file.

This sets a specific palette entry to the 48-bit colour specified.
Psychadelic palette shifting is now possible (X11 mode only so far).

This will allow arbitrary palettes.  In the future, we'll need an alloc
type interface for palettes.

Text colours still occupy the lowest 16 values.  This increases the size
of the screen array, but allows higher colour depth in the future.

For now, it simply ignores all APC, DCS, OSC, PM, and SOS strings.  In the
future, these may be used for things like background mp3 control, Sixel
graphics, and whatever else is cool string stuff.

For now at least it's not as broken when strings are sent.  :-)

YOUR WELCOME!

Update everything to use that instead of 0x00 and 0xff.  Should only impact
the use of the close window control in Windows, X, and macOS.
