This is an initial attempt at adding support for hilite_pet and
hilite_pile to the msdos tile implementation, using the new
decal.txt tiles.
This initial attempt only supports a 16-bit vesa mode.
Other vesa modes and vga have not been done as of yet.
Hopefully, someone more familiar with vesa might contribute
improvements and support of the other modes at some point.
win/share/decals.txt contains (initially) a decal_delimiter tile,
a decal_pet tile, and a decal_pile tile.
The latter two can be used for hilite_pet and hilite_pile implementations
that don't have something in place already. The implementation would
just need to apply (merge) the non-background decal pixels over a
regular tile.
The special decal_delimiter tile can be used to confirm the presence
of the delimiter tiles in the tileset and mark the end of the regular tiles,
and the start of the decal tiles.
row 1 contains the background color whose pixels should be
ignored when applying a decal to a tile.
row 2 contains a row of pixels colored (0, 0, 0).
row 3 contains a row of pixels colored pure green (0, 255, 0).
row 3 contains a row of pixels colored pure blue (0, 0, 255).

Enable USE_BUFFERING for the structlevel savefile write path on AMIGA
and TOS via a new SFSTRUCT_BUFFERING config define, with a 16 KB
setvbuf on the fdopen'd write stream so many small bwrite()s coalesce
into few dos.library Write() packets. Leaves mread() unbuffered.
Mainline UNIX/WIN32 are unchanged (setvbuf is gated on the new define);
MAC68K is not enabled, avoiding fdopen()/fclose() on its remapped
non-libc file handles.
Use LUA_VERSION_NUM, not LUA_VERSION_RELEASE_NUM, for the check.
Move the definitions of the versions supported by this release of
NetHack to the top of nhlua.c, rather than 2300 lines into the file.
Close#1633
In previous versions of NetHack, setting -DUSE_TILES enabled the tile
support, while setting -DSUPPRESS_GRAPHICS produced a NetHack that
would write its TTY output to standard output, and rely on ANSI.SYS or
similar to do screen control. (USE_TILES is now TILES_IN_GLYPHMAP.)
This change ensures that the current NetHack can be built the same
ways.
One twist is that previous NetHacks would drop all support for graphical
modes when tiles were not supported. Thus sys/msdos/vid{vga,vesa}.c have
very disordered use of TILES_IN_GLYPHMAP. There was no need to check
this. But now, the graphical modes also support Unicode. A non-tiled
build should have the graphical modes, with only the text functions
present, provided that ENHANCED_SYMBOLS is defined.
Some unused and locally used symbols were cleaned up along the way.
In 16 color mode, text colors are mapped onto the colors available in
the tileset. The mapping is a compromise, and is not one-to-one: cyan
and bright cyan are the same, and magenta and bright magenta are the
same.
This change defines a separate palette for use by the text map, and
switches palettes on any transition between text and tiled maps.
During a synchronous save operation initiated by the player (or
other trigger for dosave0()), the u.usteed_mid and u.ustuck_mid
values get set by savemonch(), and the monst pointers that
u.ustuck and u.usteed point to are no longer valid, but not
cleared.
The checkpoint operation, which also needs to ensure that
u.ustuck_mid and u.usteed_mid are set, must set them during
the checkpoint, which is okay because the u.usteed and
u.ustuck pointers _are_ valid during a checkpoint operation.
So, we need to distinguish between a save game sequence,
and a checkpoint sequence when writing out the u struct.
* In both the 16 color and the VESA mode, the tileset image is loaded
and split into individual tiles; the tiles are then processed into a
form that is compatible with the video mode in use. For 16 color mode,
a tile is processed each time it is displayed, leading to slow
redrawing. For VESA mode, each tile is processed at startup, leading
to long startup times. Both modes are changed so that the tile is
processed once, when it is first displayed, and the result is cached.
* Use memcpy when splitting the image into tiles.
* Only load the tileset once. In 16 color mode, for reasons I do not
understand, the gr_init function is called twice, leading to delay
in startup. This does not happen in VESA mode.
