This allows subclasses to override it, as is necessary for e.g. the
video-crop meta. It is now necessary that after decide_allocation()
there is always a allocator and a configured buffer pool inside the
query.
Video base classes and theora plugin still needs to be ported again

Some container formats (like AVI) set DTS on the buffers instead of
PTS.
We detect this by:
* detecting if input timestamps are non-increasing
* detecting if the order the frames come out is the same as the order
they were inputted (meaning the implementation is reordering frames).
If the decoder reorders frames, but input buffer timestamps were not
reordered, that means the buffers has DTS and not PTS as their timestamp.
If this is the case, we use set the PTS of the outgoing frames in the
same order as they were given to the decoder.
This fixes the issue for any decoder using this base class (yay).
Rename the frame_flags to flags. Because they are flags on the frame object it
does not need the redundant frame_ prefix.
Change the order of the metadata constructor so that the flags come before the
format and dimension arguments.
There's a new GstVideoFrameFlags enum now that contains the frame
specific flags only. GstVideoFlags does not contain the TFF/TFF/ONEFIELD
flags anymore because these are strictly frame specific.
Also add fallback to parse these fields from the GstBufferFlags in
gst_video_frame_map() if there's no GstVideoMeta attached to the buffer.
When setting its config, the pool increase the ref count of the allocator, but
at finalize the ref count is also increased rather than decreased.
This one-liner patch changes the gst_allocator_ref() for gst_allocator_unref()

gst_buffer_set_qdata() will leak the structure passed to it
when called incorrectly (e.g. on a non-metadata-writable buffer).
This is expected, but we must avoid doing that in valgrind.
Try to avoid floating point maths for each pixel to be blended in
inner loop, and try to avoid the multiplication entirely for the
most common case of the global alpha being 1. Could probably be
refactored a bit more.
extract_alpha and apply_global alpha always return TRUE really,
so just do away with the return value. Convert a g_return_if_fail()
into a g_assert(), since this is only to check internal consistency
and not a guard for public API. Add some locking.
