7e90867487 pcm: drop unused sys/shm.h inclusion
This header isn't used in these files, so stop trying to include it.
This helps builds on systems that don't provide the header (such as
Android/Bionic).

622b1b6bdb pcm: fix return value of snd_pcm_share_slave_avail
The return value was wrong for playback if slave->hw_ptr was near the
boundary and *pcm->appl.ptr was near zero. The wrong result was greater
than the boundary.

65ff6fdafb pcm: Implement timestamp type handling in all plugins
Now all PCM plugins do support the proper timestamp type or pass it
over slaves.  The internal monotonic flag is dropped and replaced with
tstamp_type in all places.

03c26d0ede PCM: Fix conflict of _snd_pcm_hw_params definitions
Fix the call of _snd_pcm_hw_params() to _snd_pcm_hw_params_internal().
The build passed wrongly because of _snd_pcm_hw_params define.
Having the same function name as the struct name is is simply
confusing...

Also, to be sure, _snd_pcm_hw_params is undef'ed in pcm_local.h, too.

8b14625cc3 Make all the PCM plugins ops structure constant.
This ensures they are emitted in .data.rel.ro rather than .data.rel,
which should make a nice difference when using prelink.
