Adding the compatile profiles when we decide the final profile used for decoding.
The final profile candidates include:
1. The profile directly specified by SPS, which is the exact one.
2. The compatile profiles decided by the upstream element such as the h265parse.

This is a work-around to identify some main profile streams having
wrong profile_idc. There are some wrongly encoded main profile streams
which doesn't have any of the profile_idc values mentioned in Annex-A,
instead, general_profile_idc has been set as zero and the
general_profile_compatibility_flag[general_profile_idc] is TRUE.
Assuming them as MAIN profile for now.

The segmentation is stateful, its information may depend on the previous
segmentation setting. For example, if loop_filter_delta_enabled is TRUE,
the filter_level[GST_VP9_REF_FRAME_INTRA][1] should inherit the previous
frame's value and can not be calculated by the current frame's segmentation
data only. So we need to maintain the segmentation state inside the vp9
decoder and update it when the new frame header comes.
We also fix the CLAMP issue of lvl_seg and intra_lvl because of their wrong
uint type here.

The current way of DMA buffer mapping is simply forwarding the job
to parent's map function, which is a mmap(). That can not handle the
non-linear buffers, such as tiling, compressed, etc. The incorrect
mapping of such buffers causes broken images, which are recognized
as bugs. We should directly block this kind of mapping to avoid the
misunderstanding.

We can only convert from non-cdp to cdp within the confines of valid cdp
framerates. The existing caps negotiation code was allowing any
framerate to convert to a cdp output which is incorrect and would hit an
assertion later.

Implement 8-bit values of SMPTE RP 2019-1:2014. The bar widths and
heights are the result of fractions as integers. The remainders of
widths are distributed in a way that they match the values in Table
C.1 (a) in the specification.

We are dropping RASL (Random Access Skipped Leading picture) which
is associated with an IRAP (Intra Random Access Picture) that has
NoRaslOutputFlag equal to 1, since the RASL picture will not be
outputted and also it should not be used for reference picture.
So, corresponding GstVideoCodecFrame should be released immediately.
Otherwise GstVideoDecoder baseclass will hold the unused frame.

We call gst_vaapiencode_drain() in gst_vaapiencode_change_state(),
whose context does not hold the stream lock of the encoder. The
current gst_vaapiencode_drain inside unlock/lock pair adds a extra
lock count to the stream lock of encoder and causes hang later.
We just remove the gst_vaapiencode_drain() and expand its logic
correctly according to the lock/unlock context.

If they're not dropped, they can be blocked in the queue even if it is
leaky in the case where there is a buffer being pushed downstream. Since
in webrtc, it's unlikely that there will be a special allocator to
receive RTP packets, there is almost no downside to just ignoring the
queries.
Also drop queries if they get caught in the pad probe after the queue.

GstRTPHeaderExtension::write can map the RTP buffer for reading. If that
happens on a buffer that is already mapped WRITE-only by the payloader,
the payloader's mapping gets invalidated (GstRTPBuffer::map will point
to a different instance of GstMemory).
