Fix segfault with dmix of 3-bytes formats
...
The i386 and x86-64 dmix may cause segfaults when 3-bytes formats are used
due to btsl asm code, which may overcome the buffer end-boundary.
The patch changes btsl to btsw so that it doesn't happen.

dmix: rename mix_areas*
...
Rename all mix_areas* symbols so that they contain the sample width
instead of some meaningless number.

dmix: add S24_3LE support
...
Add to the dmix plugin support for the S24_3LE sample format which is
used by 24-bit USB devices.
The optimized assembler version uses only 23 bits for sample data so
that the lowest bit can be used for synchronization because there is no
24-bit cmpxchg instruction.
