The extended PALETTE.DAT format can now carry a trailing byte, called
'lognumalphatables'. If it is present, the engine assumes that alpha blending
tables are loaded at blend indices 1 to 1<<lognumalphatables and handles
rotatesprite's alpha and spriteext[].alpha accordingly.
The ability to save this new byte is added to engine.lua:savePaletteDat()
and the corresponding convenience functions in shadexfog.lua.
Examples test/screentext.con and test/sprite_access.con are updated for
demonstration purposes.

Hook up those from test/shadexfog.lua and some debugging ones from engine.lua.

The overall situation is thus as follows:
- in C and from Lua, that member is called 'fogpal'
- In CON (both C-CON and LunaCON), it's 'fogpal' with 'alignto' being an alias;
'filler' wasn't available before, either.
- In m32script, it's 'fogpal' or 'alignto' ('filler' is not available any more)

The state quries the user for four values: ref. picnum, target picnum, max.
ldist and a lotag. Then, for all sprites i (of ref. picnum), for all sprites j
(of target picnum), if ldist(i,j)<=maxldist, sprite j's lotag is changed to the
provided one.
Also add lunatic/test/maputil.lua, containing a similar function but allowing
to customize the selection predicates of the ref. and target sprites, as well
as the action to carry out.

In C and Lunatic, split 'jumptoplayer' of enum amoveflags_t / action.MOVFLAGS
into 'jumptoplayer_bits' and 'jumptoplayer_only' (see updated Lunatic doc).

That is, always bitwise-OR the per-tile actor flags with the existing ones.

Reserved bits are those that have no predefined SFLAG_* label in CON.

This flag is set from C for some enemies that should not be pushed back when
damaged, such as TANK. Both the tile flag and the per-sprite flag are used
(i.e. the ultimate flag value is the XOR of the two).
Add currently non-functional example to test.lua that attempts to set this bit
for NEWBEAST.

Unlike in C-CON, it only tries an exact match with the given and uppercased
label, not "full" case-insensitive search.

It now accepts a number of tables to create as 3rd arg. The function that
create_trans() takes as the 2nd argument is now being passed
(r,g,b, R,G,B, tablei, numtables).
Rewrite create_additive_trans() in terms of it.
Rename create_128_trans() -> create_alpha_trans().

engine.setupDebugBasePal() set up the water base palette such each of the first
15 "ramps" of 16 consecutive colors has a single, "representative" color. For
example, color indices 0-15 and black, 16-31 are dark gray.
In shadexfog.lua, list remappings from LOOKUP.DAT that are expressible as
remappings of 16-tuples.

- Mapster32: before loading LOOKUP.DAT, set palookup[0][239]=239 to
make an identity map of the base shade table's shade 0

It must be a power of two in [2 .. 128]. Rewrite test/sprite_access.con's
liztroop example to account for that.
Also, add function shadexfog.create_trans() which aceepts a function
(r,g,b,R,G,B) -> blended (r,g,b) and rewrite shadexfog.create_additive_trans()
in terms of it.

See lunatic/test/sprite_access.con for a LIZTROOP that periodically smoothly
alpha-fades in and out. (Assuming that the 128 alpha blending tables from
shadexfog.create_128_trans(1) are installed.)
BUILD_LUNATIC.

Lunatic: also, add an additional argument 'moreblends' to
engine.savePaletteDat() and document that function.
See test/shadexfog.lua for a "user-friendly" wrapper shadexfog.save() which
prints success or errors.

The function now writes out a full PALETTE.DAT: base balette, shade table and
translucency table.

On the C side, slightly rewrite (now) getclosestcol_lim() for clarity.
git-svn-id: https://svn.eduke32.com/eduke32@4308 1a8010ca-5511-0410-912e-c29ae57300e0
Currently, sprite[].filler (to be renamed) selects a blending table. If none
is installed with that index, the blending table at index 0 is taken (which is
read from PALETTE.DAT on engine startup). Thus, for now, the non-Lunatic build
will never use a custom blending table because there's no way to register one!
But the functionality is there.

In the non-Lunatic build naturally, since the Lunatic one uses its own member.
