The check is dead because it is made after the fact (oob access), but the
cheat string matching logic below actually assures that
cheatbuflen < sizeof(cheatbuf) at all times.
Exposed using the Stack tool from http://css.csail.mit.edu/stack/ .
Also, in gamedef.c's definecheat handling, print the string length (19), not
the buffer length (20) if the cheat was truncated.

Clang's UBSan reports this as undefined behavior. I think that the reason
is as follows: C99 6.5.3.2#1 (Constraints) says:
The operand of the unary & operator shall be either a function designator, the
result of a [] or unary * operator, or an lvalue that designates an object that
is not a bit-field and is not declared with the register storage-class specifier.
But in case of an expression like "&array[-1]", the operand ("array[-1]") does
not designate a valid object.
Moral: check first -- assure that an expression is valid for a particular
operation before carrying it out. Keep in mind that otherwise, the compiler
is absolutely free to optimize out the *check*.

- 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.

The old extension is an artifact from when I was thought that extensions
should label whether a Lunatic module is to be used in internal/external
contexts.
Also, change test.lua slightly and commit a little updated documentation.

It was only ever used as upper bound to the time that a visibility change
decays, but since it does that in an exponential fashion, there's really
no point.

Now, if p->visibility differs from the constant visibility, the former converges
toward the latter by three-quartering the difference each second totalclock
increment (1/60th second).
Negative player visibilities are not handled consistently throughout the
different renderers, so make it look the same as 0 (can view to infinity).
