8176d2c058 Load soundfont samples into an ALbuffer 
Also remove ALsoundfont's now-unneeded sample storage functions and struct
fields.

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);

94884ed04b Use a separate value for the maximum buffer channels 
Unlike the device, input buffers are accessed based on channel numbers
instead of enums. This means the maximum number of channels they hold
depends on the number of channels any one format can have, rather than
the total number of recognized channels. Currently, this is 8 for 7.1.

8b2e1fdd9a Add buffer properties to get the internal format, and the length in bytes, samples, and seconds 
The provided buffer lengths correspond to the source offsets, in that the byte
length specifies the end of the byte offset (ie, when the buffer is used for a
static source, the offset will range between 0 (inclusive) and the byte length
(exclusive)). Although an application could use the AL_SIZE, AL_CHANNELS,
AL_BITS, and AL_FREQUENCY properties to find the length in samples and seconds,
the byte length cannot be reliably calculated this way.
