1e2c1467ae Pulsesink: Allow chunks up to bufsize instead of segsize
By allowing larger chunks to be sent, PulseAudio will have a
lower CPU usage. This is especially important on low-end machines,
where PulseAudio can crash if packets are coming in at a higher
rate than PulseAudio can process them.

e18e25a324 pulsesink: Uncork stream while flushing the ringbuffer
After starting the ringbuffer, we wait for enough data to arrive before
uncorking the stream. This will cause the pipeline to stall if we get an
EOS (or otherwise need to flush the stream) before sufficient data
becomes available. This patch makes sure that the stream is uncorked
while flushing to avoid this problem.

Fixes issue with a webkit unit test testing reverse playback of
an MP4 H.264/AAC file.

7280ea1f68 pulsesink: Make corking during pause synchronous
This makes the call to pa_stream_cork() during ringbuffer pause()
synchronous, which makes sure that the clock does not advance after we
take a snapshot for start_time.

7f48fb37e9 pulse: fix device_description in READY
Make the is_dead check more clear and add an option to check for the status of

f62dc6976b pulsesink: rework context sharing
We also need to share the main-loop threads as this owns the context. Thus have
a class wide main-loop thread. From this we create a context per client-name.
Instead of always looking up the context, we keep this with the instance. The
reverse mapping is only needed in pulse singal handlers. This saves a lot of
locking. Also one signal handler becomes simpler as ther eis only one mainloop
to notify.

Now valgind happy - no leaks, no bad reads/writes.

This reverts major parts of commit 69a397c32f.

864a52d8aa pulsesink: use G_TYPE_DEFINE to define ring buffer type
The existing get_type() implementation is racy, and the
g_type_class_ref() workaround didn't actually work because
it was in the wrong function. Since class creation in GObject
is thread-safe these days (since 2.16), the class_ref workaround
is no longer needed and it is sufficient to ensure the _get_type()
function is thread-safe, which G_TYPE_DEFINE does.

3f541452c4 pulsesink: Only set the volume on stream connection if pulse >= 0.9.20 is available
In older versions the volume set during stream connection had
no defined sematic and usually it was a relative volume. What
was needed for our use case is an absolute volume though, otherwise
the volume will be always decreased on stream connection if it's
less than 100%.
Since pulse 0.9.20 that volume is always an absolute volume if
flat volumes are used and relative otherwise, which is the same
as for pa_context_set_sink_input_volume().

e4d6a2aa2c pulse: never apply volume more than once
Generally decisions on the volume of the stream should be done inside of
PA, not inside of Gst. Only PA knows how volumes translate between
devices and s on.

This patch makes sure that all volumes set via the volume property are
only applied *once* to the underlying stream. After applying them the
client side will not store them anymore. This should make sure that
really only user-triggered volume changes are forwarded to server, but
the client never tries to save/restore the volume internally.

20a6908dfd pulsesink: bps is signed int to avoid overflow
Keep bps as gint instead of guint because we will be doing signed math with it
later on and we don't want weird results.

7d438518fb pulsesink: check for a stream
Don't try to change the stream volume (and other things) when we don't have a
stream yet. Just store the values for later.

8d58de128d pulsesink: uncork fixes and use prebuf = 0
We can use prebuf = 0 to instruct pulse to not pause the stream on underflows.
This way we can remove the underflow callback. We however have to manually
uncork the stream now when we have no available space in the buffer or when we
are writing too far away from the current read_index.

81c5fb9e48 pulsesink: write silence on underflow
Start filling up the buffer with empty samples when an underflow happens. We
need to do this to keep pulseaudio reporting the right time for us.

2e2f1d73ca pulsesink: handle pull-based scheduling
Use the default basesink methods for implementing pull based scheduling, it
works fine for us.
