Not a particularly exciting set of changes.

Zeroing of fields when starting playback moved to common functions, revised allocation of memory for FLAC, Vorbis, XA, and XMP, addition of "snd_lazyalloc" cvar to control reusal of memory blocks allocated for Vorbis, XA, and XMP playback, other misc code cleanup.

This removes the +2 bytes at the end of the allocation--I checked out the valgrind_errors.log referenced by the deleted comment and it looks like the issue fixed by 2e2e0e3a.

This is the commit to revert if weird audio crashes start happening.

This adds a z position check to the collision check that controls the reversing swinging door behavior.

This only affected KMT mode, and only on certain system configurations.

which in turn is called from the engine.

a possible flicker with the drill at the end of level 2.

of change that camq16ang/camq16horiz gets. Such an update is possible
after making sure that UpdateInputs (faketimerhandler) is
never called from domovethings.

before calling UpdateInputs itself from RunLevel.

faketimerhandler stub in SW. This basically deprecates
the usage of faketimerhandler in the game.

from EDuke32-OldMP. Main difference from EDuke32-OldMP is that this is
done even while staying in the menu; Behaviors will otherwise break.
We should also call timerUpdateClock() before the loop, especially
after removing the call to this function from faketimerhandler soon.

of the secret rotating pillar in level 1 with SO interpolation.
The drill in level 2 is also covered. So far, SetVatorActive seems
to be the only place where interpolation of ceiling/floorz
may be set, outside of the SO interpolation code.

The logic here is incorrect when considering anything run from within G_DoMoveThings() that may directly trigger drawing.

Same as JFBuild commit 274d8d886dde7cac081acf9698348d1168c18852

This way running both from the same folder won't invalidate the cache.
