f3a87d72b2 Add an extension to alter the block alignment for buffer unpack/pack ops 
This is for unpacking (reading, e.g. alBufferData) and packing (writing, e.g.
alGetBufferSamplesSOFT) operations. The alignments are specified in sample
frames, with 0 meaning the default (65 for IMA4, 1 otherwise). IMA4 alignment
must be a multiple of 8, plus 1 (e.g. alignment = n*8 + 1), otherwise an error
will occur during (un)packing. Chenging the block alignment does not affect
already-loaded sample data, only future unpack/pack operations... so for
example, this is perfectly valid:

// Load mono IMA4 data with a block alignment of 1024 bytes, or 2041 sample
// frames.
alBufferi(buffer, AL_UNPACK_BLOCK_ALIGNMENT_SOFT, 2041);
alBufferData(buffer, AL_FORMAT_MONO_IMA4, data, data_len, srate);
alBufferi(buffer, AL_UNPACK_BLOCK_ALIGNMENT_SOFT, 0);

ef8002a832 Check the hrtf config option earlier 
This is to make sure it tries to find an HRTF-compatible format before reseting
the device, just like when using ALC_HRTF_SOFT.

540a99e71f Allow "deleting" the default soundfont 
The ID remains valid and the soundfont will be reloaded as needed, but this
provides a way for the application to clear up the soundfont memory.

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.
