It is unacceptable that yvel is on one hand modifiable without restriction from
scripting, but can be used as an array index without prior bound check in the C
code. Because that member has an overloaded meaning and is also used for
innocuous purposes such as the green color intensity of an SE light, it's
infeasible to restrict access from scripting. Consequently, we must add bound
checks on the C side. This is the first part of the effort to make .yvel safe,
adding two functions P_Get() and P_GetP(). There are a couple of other uses as
some kind of index.

- in the function itself: for floor, currently, do nothing (but this commit
is in preparation of the next one, again)
- In Proj_MaybeDamageCF(), Proj_MaybeDamageCF2() and the A_RadiusDamage() use
if the function, generalize to floors, but with the special case that
parallaxed floors keep blocking projectiles, as before (in constrast to
parallaxed ceilings). However, Sect_DamageCeilingOrFloor() is only
called for non-parallaxed ceilings *and* floors.

The scrollwheel is unique among PC input because it has no innate "hold length". Previously, the layers gave the mousewheel a fake hold length to allow the not-necessarily-synchronous game/editor code to pick up the input before the layers marked it as "no longer pressed". This passed under Windows, but it didn't slide under SDL.
Besides the two problems listed above, it also potentially limited the rate of weapon selection, where scrolling too fast would not register every clicks. [Unrelatedly, this is still the case when you scroll faster than the game's own tickrate, but addressing that would require rewriting input handling to go through a list of "events" for each tic instead of looking at overall pressed/unpressed states.]

- Move ARRAY_SIZE() macro to compat.h, add another one ARRAY_SSIZE()
- In A_RadiusDamage(): note maybe-unaligned access issue, prevent unlikely oob
- sector.c: use SPRITES_OF* macros where appropriate

This requires enabling the same workaround as for Linux. Maybe it's not

This generally fixes demo playback. Before, tilesizx[]/tilesizy[] were written
into twice as many bytes as needed. Now, don't do that at all.

I was checking for GCC >= 4.7, while Clangs pretends to be GCC 4.2. Use a
feature test macro instead. The comment I made in r4161 regarding GCC vs.
Clang code was wrong. Now, Clang generates slightly faster code for these cases
(solid and masked 4-pixel wide vlines).

In particular, (int32_t)j != -1 is replaced by (uint32_t)j < MAX_WEAPONS
to prevent a value >= MAX_WEAPONS to be assigned to p->wantweaponfire (it's
used as a weapon index in P_CheckWeapon().
