keysound: support keysound priority

- The new higher(or the same) priority plays after
  stopping the previous lower(or the same) priority playbacks.
- If the new playback is lower priority, then will be no operation.
- The priority with -1 will be mixed always with others,
  no matter what other playback's priority is.

Fix to start stream corked to avoid early drain complete

For short file playback, drain operation can be completed to early prior to actual stream start.
This is due to connecting playback stream with uncorked.
In this situation, stream handle will not be valid any more and finally crash occurred.

   remove the previous signal handler for cleaning focus resources.
 - Response time is enhanced as per the change of IPC.(DBus to socket)
