Alexandre Ratchov 285eafeec0 Add affinity between the program and its mixer control. 
Currently, if there are two instances of the same program, sndiod will
allocate one volume control to each. If both programs disconnect and
reconnect, the information of which control is assigned to which
program is lost. This makes difficult to run two instances of a player
and crossfade between each other with a MIDI controller.

To address this, the program chooses a 32-bit "id" (for now the
process pid) and sends it to the server. The server records the id in
the client's slot structure.  When the server accepts a new
connection, it uses the id to identify the slot the client used during
the previous connection; if it was not recycled yet, it's assigned to
the program.

Alexandre Ratchov 6ac10f167b Wait until the server disconnects before closing the socket. 
When the socket is closed, the last bytes written may be lost.
