Most often, this had happened when casting comparison functions for qsort()
like these: "int yax_cmpbunches(const int16_t *b1, const int16_t *b2)"
to a function pointer type expecting "const void *". Alas, this is undefined
behavior: see
http://blog.frama-c.com/index.php?post/2013/08/24/Function-pointers-in-C
and posts linked from it.
At least two cases have not been fixed:
- The savegame system maintains pointers which are either to data or a function in
the generic "void *". This ought to be made into a union.
- Probably also:
#define OSD_ALIAS (int32_t (*)(const osdfuncparm_t*))0x1337

DONT_BUILD, because there have been no significant changes of the non-Lua build.

- libs and headers are expected in platform/Windows/* (not there yet)
- prefix Lua #includes with luajit-2.0/
- build bytecode objects with absolute path name (used for debug info)

- Rename sky_t members: yscale -> horizfrac, bits -> lognumtiles.
- Add default sky (8 tiles, horizfrac=32768 (i.e. 1/2 the scene horiz), offsets
all zero) and CLOUDYOCEAN sky (8 tiles, horizfrac=65536, offsets all zero)
to multipsky[].
- Get rid of "psky_t g_psky", merely maintaining a g_pskyidx instead. Set it up
at map load time so as to keep the behavior of the legacy per-map psky:
the last sector index with a matching psky ceiling wins.
- In mapstate_t, save g_pskyidx too, not (former) pskybits and pskyoffs[].
- Make on-map-load global psky setup consistent for the game and editor by
factoring it out into common.c: G_SetupGlobalPsky().
- Remove a couple of useless initializations, add some static assertions.
This commit is more likely to introduce subtle differences in behavior.
Specifically, getpsky() now always returns the default sky properties instead of
the global sky ones (but with all-zero offsets) when no match for a suiting
multi-psky is found. This is only likely to affect the yscale/horizfrac of
non-multi-pskies when a global non-default multi-psky has been set up.
Bump BYTEVERSION again.

- Consolidate psky* arrays into a "typedef struct psky_t" "g_psky" and
"multipsky[]".
- Factor out getting parallaxed sky properties into getpsky().
- Condense initial multi-psky setup by memcpy'ing from multipsky[].
- New function: MultiPsky_TileToIdx().
- Add new define PSKYOFF_MAX and related consistency-checking assertions.
- Lower MAXPSKYTILES to 8 to reflect current usage (was 256).
- Game: make multi-pskies consider dynamically-remapped MOONSKY1, BIGORBIT1
and LA. (Not very useful as the editor will still only act for the static
values -- 80, 84 and 89, respectively.)
An attempt has been made to preserve behavior even in strange cases, so this
commit is unlikely to introduce regressions. Because of point 6, BYTEVERSION
had to be bumped.

Having to tag these few variables and functions as ATTRIBUTE((used))
seems sensible, but what follows is just strange. OSD_Printf? headspritesect?

Also, get rid of the strange filename[len]=255 hack in loadboard()
and make its file name arg const char* at last.

Also, clean up the saving/loading logic a bit:
- On load failure, display message with purple color.
- Take over the current file name ('boardfilename') only on success.
- Check SaveBoard() return values in various places.

In 3D mode, Alt+F now only attempts to set the first wall of the aimed at
wall, not collecting upper/lower neighbors. For this, press Shift+Alt+F.
In 2D mode, they are always collected.

Analogously for the negation; remove a couple of redundant decls of "qsetmode".

The 'x' is for "extended", since its last arg is a switch of whether to disable
sliding. Use that from gameexec.c.

Also, add some defines for sprite cstats to build.h (SPR_*) and use them.
