The audio library considers them as encoded formats and does not fill in the
sample width. The audio ringbuffers identifies the format as alaw/mulaw and that
is always 8 bits.
This reverts commit 01457027e0.
We'll just depend on PulseAudio 2.0 or above instead of having the bug
partially fixed based on the installed libpulse version.
The getcaps function we added uses some pa_format_info_get_prop...
accessor functions that were only added in 2.0, so we only have our
getcaps implementation exist if we're compiling against libpulse 2.0 or
above.
Eventually, we could bump the minimum requirement to 2.0 or above.

getcaps is called frequently during stream setup, and creating a new
stream each time is very inefficient. There's some more room for
optimisation by caching the queried sink formats as well, but this needs
some more changes to listen for format changes on the sink (for when
supported formats change between probe stream creation and sink
querying).

This allows us to have more fine-tuned caps in READY or above. However,
this is _really_ inefficient since we create a new stream and query sink
for every getcaps in READY, which on a simple gst-launch line happens
about 35 times. The next step is to cache getcaps results.

This makes sure that we update segdone based on the read index received
during latency updates. As the comment notes, we make some compromises
to deal with the fact that segdone is a segment multiple, while the read
index offers finer granularity. The updates are also not very often
(100ms since that is how often automatic timing updates are provided).
All this is required for the baseaudiosink sample alignment code to work
at all.

A bug in PulseAudio causes PA_STREAM_START_MUTED to be rejected on
record streams. Until this is fixed upstream, we mute the stream
manually at startup. Based on a patch by Alban Browaeys
<prahal@yahoo.com>.

When we start and renegotiate, there is a moment where the stream is created but
not yet connected. Make sure all functions deal with this situation correctly
instead of erroring out.

When get_time is called but we are not yet negotiated, return 0 instead of
posting an error. It's possible that the base class is still negotiating when
our get_time is called.
