9959972c7e Add a stub 'soft' MIDI synth handler 
Eventually this one will be used to handle MIDI internally, using our own
mixers and resamplers.

7640c658ee Remove explicit locking from alMidiSoundfontvSOFT. 
The MIDI backend can lock as it needs.

37d183efc0 Update soundfont selection functions 
A filename is no longer specified, and alMidiSoundfontsSOFT is renamed to
alMidiSoundfontvSOFT.

fe55cd6de8 Add alLoadSoundfontSOFT to load a soundfont via callback 
Some hefty caveats:
This function is not thread-safe. In particular, the current context affecting
the thread must not be changed, and the provided soundfont must not be
altered while the function is executing. Ideally, this will be fixed.

Error handling is poor. Some RIFF structure errors may not be caught (e.g. sub-
chunks with sizes greater than the parent chunk allows for), and generated AL
errors are ignored, possibly leading to resource leaks in certain situations.
These should be fixed in time.

There is minimal error checking on the provided soundfont ID. It does not
ensure a valid ID has been provided, nor does it ensure the provided soundfont
can be modified. These short-comings should be fixed eventually.

Proper cleanup is the responsibility of the caller. The caller must get the
preset objects from the soundfont before deleting it, and the fontsound objects
from each preset before deleting them, to make sure all resources are properly
deleted.

f85d733f9d Add a method to set and get soundfonts 
The main purpose of this is to select soundfonts for playback, eventually,
instead of the existing method that takes a filename.

189d73dd87 Render some MIDI samples even when stopped 
Because stopping MIDI playback puts any playing notes into release phase, they
should be rendered. Ideally it could stop rendering once output goes silent.

1dd05bac5c Add a alMidiResetSOFT method to reset the synth 
Playback is stopped, the queue is flushed, the clock is reset to 0, and the
MIDI system is reset to power-up status.

a343d78724 Update behavior for alMidiStopSOFT 
alMidiStopSOFT now has the following behavior:
* All pending MIDI events up to the current time are processed first, before
the queue is flushed.
* All channels then receive an All Notes Off event so that notes go through
their release phase. Controllers are *NOT* reset.
* Clock time is reset to 0, like before.

f8c68291d3 Add a method to stop MIDI playback 
Unlike pausing, this resets the MIDI clock time to 0, clears the existing event
queue, stops all MIDI sounds, and resets MIDI controllers.
