884fe40fd1 Store mulaw and alaw samples directly in the buffer 
They're now decompressed on the fly in the mixer. This is not a significant
performance issue given that it only needs a 512-byte lookup table, and the
buffer stores half as much data (it may actually be faster, requiring less
overall memory).

355a8898cf Remove the (u)byte3 sample formats 
They're not accessible since the removal of the buffer_samples extension, and
were kind of clunky to work with as 24-bit packed values.

a758cc8243 Remove use of DECL_CONST 
No idea if it was really gaining us anything, but removing it fixes a crash I
was getting with libs built with Clang.

It's not particularly good, but it's better than silence.

f82f3f10ab Use specialized methods for converting IMA4 and MSADPCM to ALshort 
Since the decoder methods already convert to ALshort, there's no need to use a
temp buffer that's just going to copy directly to the destination.

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);

a2d9133ffc Reduce explicit template declarations and ignore IMA4-to-IMA4 conversions 
Since we never store IMA4 data in buffers, we should only ever convert from
(user input) or to (user output) IMA4. Once we allow user-specified pack/unpack
block alignment, this wouldn't be a simple memcpy anyway.

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.
