Among other things, rotatesprite doesn't cope well with large zoom values.
Two assertions are added that guard qinterpolatedown16short() calls: in
the failing case, they would write outside the destination arrays.
Another (existing) assertion is commented a little and like for the first,
instructions are given how to reproduce its failure.

... in the auto-correction. Also,
- make two similar corruptions level 5 (wallptr oob, wallptr+wallnum oob).
- in drawscreen_drawwall(), do a more strict bound check, not only >=0.

The visibility calculation relies on the distance, which might not be entirely
accurate in rotatesprite, so maybe it'll be too dark in some cases.

In the mirror reversing code, get rid of the padding. This may produce
seams, but they appear to be extremely transient and shouldn't be
noticeable.
In game.c, add a debugging compilation switch DEBUG_MIRRORS_ONLY.

No functional changes, but a (commented out) debug line for an oob read of the
frame buffer when the mirror covers the whole screen is inserted.

- Return early from drawsprite_classic() if tspr->owner if oob.
Commonize that check between renderers into bad_tspr().
- Make the BIT() macro a left-shift of the *unsigned* number 1,
preventing expansion to (1<<31).

In those Clang versions, -fcatch-undefined-behavior was replaced by
-fsanitize=<what>. For Clang 3.2, we enable the address sanitizer
and for 3.3 also the miscellaneous undefined behavior one.
Currently, there's no version auto-detection from the Makefiles, it's
set to 3.3 and the others are commented out.

LameDuke's shade table has 32 gradients of shade, like Duke3D.
For the translucency table though, only the diagonal + one half is stored
because it's symmetric (50/50 translucency).

Sprites are now considered to have out of bounds sector numbers if it is
< 0 or >= numsectors (not merely >= MAXSECTORS). If such a sprite is now
encountered during post-load, an attempt is made first to assign it a sector
number (using updatesector()). If that fails, the sprite is removed from the
map. The background is that a dozen of maps do come with such sprites and
could previously corrupt the sprite list when loaded.

Specifically, in GL modes, and if the CHAINGUN is not replaced by a model,
- draw the upper part twice: first, two screen pixels * weapon scale lower,
then at the original position
- reverse the previous order: draw the upper part first, then the lower part
This is much preferable to the previous engine-side hack, and to my eye,
it looks perfect now.

- Rewrite some sprites-of-{stat,sector} loops using the SPRITES_OF,
SPRITES_OF_SECT and new SPRITES_OF_SECT_SAFE macros.
- In passing, identify some problems and mark them with 'XXX', but don't
attempt to fix them yet.
- The usual readability improvements...

(Note: We are still vulnerable to crashes here (and likely in other places), but you have (4096-16) extra characters to work with. We should consider replacing many uses of Bsprintf with Bsnprintf.)
