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.

4433248bf3 remove superfluous free() checks

4d7c53d280 Add snd_pcm_hw_params_get/set_export_buffer() 
Add snd_pcm_hw_params_get/set_export_buffer() API functions.
They control to ensure the buffer export to other processes.
If this flag is set, the local buffer of a plugin is exported over IPC shm.
Otherwise the buffer can be handled only locally (no shm).

Also fixed Version file for 1.0.9.
