Add snd_pcm_hw_params_get/set_export_buffer()

Browse source 
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.
