03274a5b95 Ensure at least the specified ringbuffer size is writable 
Previously, all but one of the specified size could be written (so for a size
of n, only n-1 was guaranteed writable). All users pretty much compensated for
this, but it makes more sense to fix it at the source.

And rename alcRing.c to ringbuffer.c for consistency.

82a990e08e Downgrade some ERRs to TRACEs 
These don't exist outside OSSv4, e.g. with OSS/Free, padsp, or aoss, so no need
to be concerned.

2e1f1449bc Don't remove a period from the OSS buffer 
Since we're now waiting for space to be available before mixing, the mixing
buffer isn't adding another period.

6d4380a48c Change the backend getLatency method to return the clock time too 
This will also allow backends to better synchronize the tracked clock time with
the device output latency, without necessarily needing to lock if the backend
API can allow for it.

1fb9311d82 Lock the device before calling aluHandleDisconnect 
PulseAudio causes an assert if being relocked inside a callback on the worker
thread, where aluHandleDisconnect is called. We can assume it's already locked
there, so just make sure the device is locked before being calling it.
