Fix playing ambient sounds at max volume for split sec on entering their range.

This is done by always calling FX_PlayAuto3D() to play such sounds. It now
additionally takes a third argument 'loophow', permissible values being
FX_ONESHOT and FX_LOOP.

In 'tip' display code, extrapolate four more values of the y coord table.

Also, for tip_incs values greater or equal than the number of elements in
this table, return early reporting that the hand has been drawn, so that
the otherwise selected weapon is not drawn.

Lunatic: chaining of actor callback functions.

For events and actors, a flag can be now passed whether to chain the new
function at the beginning or end of an already existing one, or to replace
it entirely.
Also, for the translator, add option -fno-error-nostate, disabled by default.

Add rudimentary sanity checks when playing ANM files.

- Don't attempt to play an ANM file if it is empty (warn) or too short (error).
- If failing to read IVF file header or initializing VPX codec, don't play ANM.
- Return early from gltexapplyprops() if not in GL modes.
