3d0843e8ce test/pcm.c: Fix S24 format 
S24 format has different bit width and physical width.
For calculating the byte offset for big-endian packing, the latter value
has to be used.

d31fd52e74 test/pcm.c: Fix SND_PCM_FORMAT_S24 support 
The program uses snd_pcm_format_width() wrongly to calculate the sample
size.  It must be snd_pcm_format_physical_width() instead.

8aaccc9484 Implemented snd_pcm_sw_params_(set|get)_period_event for interrupt wakeup like behaviour 
Actually, PCM timer is used as source for poll(). It might be optimized
in the kernel code later.

cf15e49d84 Remove PCM xfer_align 
The PCM xfer_align is a removed feature from the kernel.
This patch cleans up the corresponding part in alsa-lib.

23ed7623c6 Maarten de Boer <mdeboer@iua.upf.es> 
The attached patch makes the alsa-lib/test/pmc.c generate_sine code
slightly more simple, efficient and readable (but not less accurate),
taking quite some calculation out of the loop.

7f3942d827 Reverted back the PCM API. 
New snd_pcm_hw_params_* functions are available only explicitly when
ALSA_PCM_NEW_HW_PARAMS_API is defined.

b9343e0834 - unified snd_pcm_hw_params_* functions 
- added backward compatibility for older non-compatible functions
- added --with-compat-rc3 to configure script to build library
  backwards compatible with 0.9.0rc3
- added symbol versioning like libc.so.6
  - ALSA_0.9      - alsa base
  - ALSA_0.9.0rc4 - first set of new functions (snd_pcm_hw_params_*)
