803cf23380 Split dev_open() in two parts. 
The first part resets audio parameters to the prefered ones, the
second part opens the device and allocates the audio buffers. No
behavior change.

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.

d2985fff2b Replace the "umap" bitmap by a simple table of slot pointers. 
Makes the code simpler at virtually no cost since we need 8 entries
only. No behavior change.

cbdd29c403 alsa: use (blksz - round) as start threshold. 
The threshold making poll() return POLLOUT is one block (according to
alsa library sources). If a poll-based program writes blksz - 1
samples, playback never starts but poll won't return POLLOUT either.
In turn the program deadlocks. The problem could be observed in the
sio_alsa_xrun() routine.

ed64776ceb sndiod: Remove redundant slot->tstate variable. 
It was used to determine whether the slot obeys MMC and is ready
to start. The stop->opt->mmc flag indicates if it obeys MMC and
the slot->pstate == SLOT_READY indicates if it's ready. So
slot->tstate can be safely removed.
