0846ceef59 appsink: don't signal the GCond if no one is waiting on it 
Performance optimisation: Keep track whenever the streaming
thread or the application thread are waiting on the GCond
for more space or new data, and only signal on the GCond if
someone is actually waiting. Avoids unnecessary syscalls and
thus context switches.

8b22d47057 appsink: use GstQueueArray instead of GQueue for internal item queue 
Performance optimisation.

Avoids alloc/free churn for the queue's list nodes.

8af7b1f70b appsink: fix end condition of query drain handler 
The while loop should end when all buffers "and" the preroll
buffer are consumed but this means to continue waiting if there
are still some pending buffers "or" preroll buffer.

The unit test was correct but racy because of this mistake.
I.e. because of the wrong "and" the while could finish too early.

cd tests/check && GST_CHECKS=test_query_drain make elements/appsink.forever

fc86194595 appsink: on drain wait for buffers to be consumed 
So that an upstream element can claim all buffers to return to its buffer pool.

Added unit test 'test_query_drain'
  make elements/appsink.check

7b1056b946 appsink: also clear preroll buffer in _pull_sample 
If someone calls gst_app_sink_try_pull_sample they are
probably no longer interested in any preroll samples.

Useful if the user has not registered a preroll appsink callback.

Also added unit test 'test_do_not_care_preroll'
  make elements/appsink.check
that fails without this patch.

68518acb53 appsink: unref preroll buffer upon pull 
There is no reason for appsink to hang onto the preroll buffer.
If needed, the application can just keep a ref on this buffer
after calling gst_app_sink_try_pull_preroll.

Also added unit test 'test_pull_preroll'
  make elements/appsink.check

826eec22f7 appsink: fix g-i warnings and add since markers 
Rename function parameter and make sure the name in the
declaration matches the name in the implementation, to
avoid g-i warnings. Also add Since markers for gtk-doc.

c6722c06a0 appsink: add _pull_sample/preroll() variants with timeout 
The _pull_sample() and _pull_preroll() functions block
until a sample is available, EOS happens or the pipeline
is shut down (returning NULL in the last two cases).

This adds _try_pull_sample() and _try_pull_preroll()
functions with a timeout argument to specify the maximum
amount of time to wait for a new sample.

To avoid code duplication, wait forever if the timeout is
GST_CLOCK_TIME_NONE and use that to implement
_pull_sample/_pull_preroll with the original behavior.

Add also corresponding action signals "try-pull-sample"
and "try-pull-preroll".

c411819452 appsink: put the correct segment in the preroll sample 
last_segment is only being updated in dequeue_buffer(),
which is only called from _pull_sample(). _pull_preroll()
simply re-uses an old or dummy segment while the actual
one sits and waits in the queue.

0d98aa25b8 Work around deprecated thread API in glib master 
Add private replacements for deprecated functions such as
g_mutex_new(), g_mutex_free(), g_cond_new() etc., mostly
to avoid the deprecation warnings. We'll change these
over to the new API once we depend on glib >= 2.32.

Replace g_thread_create() with g_thread_try_new().
