Adding a buffer to the end of a GstBufferList is supposed to be a fast
operation, but it was not since the iterator does not advance its
nextpointer when adding buffers and GList does not have a tail pointer.
Using a GQueue to store the buffers makes it easier to add buffers to
the end of the list and this operation will now be much more efficient.
Adding an entire GList of buffers using
gst_buffer_list_iterator_add_list() will however have to iterate over
the list being added to be able to update the tail pointer in the
GQueue.
GST_DISABLE_DEPRECATED should only affect visibility of declarations in headers,
not actually remove symbols. See GitDeveloperGuidelines and DeprecatingAPI
pages in wiki.

Add new functions to clarify how the caps are compared to the template caps of
the element factory. Improve the docs to point out the difference.
Deprecate: gst_element_factory_can_{src|sink}_caps
API: add gst_element_factory_can_{src|sink}_{any|all}_capps

Replace subbuffer and copy vmethods by a more generic transform function that
can then be parametrised by transform specific data. This should allow us to
implement make-writable and more future transform functions.
Check if structure has been created before appending it to the caps. Free the
caps in the case of an error to not conceal it be returning empty caps.

Our helloworld example thatw e reference from the manual has been a bit
complicated to serve a first contact with gstreamer. Since we have and
promote playbin2 as a playback api use it here.

Fixes#424143
Keep a pointer to the bufferpool. Release the buffer to the pool when
finalizing. Make sure the pool sets itself as the pool member of buffers that it
sends out.
Move some methods around.
Make sure we check for config parsing errors.
Increment the outstanding buffers before calling acquire so that we can be sure
that set_active() doesn't free the pool from under us.
Add start/stop methods to allow for bulk allocation of buffers.
Free buffers only when all outstanding buffers returned.
Make things more threadsafe wrt flushing and starting/stopping by
keeping track of start and stop method calls.
Use a lock to protect concurrect execution of set_config and set_active.
Start freeing the buffers when flushing and all buffers are returned to the
pool.
Make a copy of the config to avoid crashing with concurrent access.
Keep track if the buffer is configured and block activation when not configured
yet.
Keep track of outstanding buffers and disallow configuration when not all
buffers are returned to the pool. We need to do this or else we might end up
with wrong buffers in the pool.
Add return value to set_active.
Small cleanups. Fix finalize.
