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.

Smoothed using an exponential moving average... with a time constant of 1 sec

Using macros like AC_COUNT(t). Clean up related code:
- comment out the dead condition noted in the previous commit
- Lunatic: use get_count() instead of get_t_data(0) in one place,
rename to _get_t_data(), i.e. make that method internal

That is, assume that switch(DYNAMICTILEMAP(-1)) (which is an oob access and thus
undefined behavior) gets us to the 'default:' label.

- In S_PlaySound(), move the sound index bound check above an indexing.
- For A_CheckHitSprite(), and A_FindPlayer(), allow NULL second arg.
- In A_ShootWithZvel(), make some one-letter vars be int32_t, making
storing safeldist() results in them meaningful.
- In MaybeTrainKillEnemies(), remove two redundant checks and move another
one further up.
- Comment that SIDEBOLT1 will never be translucent as was probably intended.
- In G_MoveFX(), fix an always-true comparison.

Actually, the tweaked code in VM_Move() is not specific to projectiles, so
other sprites now may pass no-SE7 water boundaries too, but it's most noticeable
with projectiles.

That is, if submerging, the lower sector MUST have lotag 2. If emerging, the
upper sector MUST have lotag 1. (Previously, emersion happened from ST 2 sectors
unconditionally.) This means that the area where submersion or emersion can
happen is now the same for the top and bottom parts.

This is done by always calling FX_PlayAuto3D() to play such sounds. It now

With this change, it is impossible for negative values to be used as array
indices inside this function, and I believe that it is also impossible that
they escape to somewhere they might be used as such.
For Lunatic, allow setting actor[].picnum to negative values and in the
translator, add (commented out) code to warn whenever it is set to a constant
negative value. Also, fix a _sound call in _addphealth in control.lua.

This should have no adverse effects or side-effects. The changes only apply if a modder chose to use completely broken functionality in the first place.

Use a new flag to mark hard-coded enemies, not SPRITE_BADGUY.

Also, add another flag, signifying that from the editor, also the
"lastwall"s (i.e. the CCW-linked points) should get collected. This is
to signal the editor that their wall lengths should be displayed, too.

In the normal game, these arrays are conceptually [MAX_WEAPONS][MAXPLAYERS],
allocated as CON per-player gamevars (e.g. WEAPONx_WORKSLIKE).
For Lunatic, they are replaced with
weapondata_t g_playerWeapon[MAXPLAYERS][MAX_WEAPONS].

Rotation-fixing happens for a couple of hard-coded statnums that presumably
never move (DEFAULT, STANDABLE, FX, FALLER, LIGHT), but for actors it wouldn't
make sense since the common case is that they do move. For this reason, bit 4
was introduced in r1934. The position of such useractors will not diverge
due to error roundoff accumulation in rotating sectors (SE0, train).
