This also exposes an actual issue. The sound definitions may be dynamically
remapped, in which case they are not necessarily <=255 any more.

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

Also, add hitscan test to test.lua -- a crosshair-like sprite is spawned
and continuously updated to the position of where the player aims at.

The offsets (that will translate the axes for .pitch/.roll rotation) were
calculated improperly with screen sizes other than 1280 x 1024 and were
dependent on other related variables. The fix proceeded empirically, i.e. mostly
trial, error, and some educated guesswork. (It's telling that the magic constant
1280 is needed.) A test for Lunatic is added to test.lua that will rotate
SEENINES.

- Need to open some files in binary mode.
- MinGW's "find" doesn't provide -L option, detect that.

Specifically, for the tables returned with require"DEFS" etc. This allows to
check if maybe parts of a bundle of files is missing (because comparisons like
"spr.picnum == D.NONEXISTENT_NAME" do not yield errors normally).

Permitting to enable various debugging options. See "eduke32 -debughelp"
for which ones those are: they were previously settable from defs_common.lua,
and a new option 'strict' has been added that makes accesses to void sprites
error. (That is, already "sprite[i]", not "sprite[i].some_member".)

On the C side, keep the name g_RETURN. I'm still superstitious about
dropping the "g_".

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*.
