For example this allows the omx decoder to directly fill the
pixmaps coming from the video sink.
It only avoids a buffer copy when the decoder uses a pool provided
by a downstream element. So let's restrict this usage to situations
where the decoder decides to use a downstream buffer pool.
Tested with Tizonia/OMX.Aratelia.video_decoder.vp8
and with Bellagio/OMX.mesa.video_decoder.avc.
If it fails to setup buffers with OMX_UseBuffer the decoders
fallbacks to usual OMX_AllocateBuffer.
Also it allows to test on desktop the GstOMXBufferPool->other_pool
management which was previously only used in the OMX_UseEGLImage
case, i.e. on Rpi.

gst_omx_video_dec_open will only update GstOMXVideoDec->port->port_def.
Note that the component is reopen only if the flag
GST_OMX_HACK_NO_COMPONENT_RECONFIGURE is set.

Ensure that enough buffers are allocated by adding up component's own
minimal plus the number of buffers requested by downstream.
This should prevent buffers starvation problem if downstream elements
are holding some of the buffers they required.
Also simplify the check on the maximum on buffers. What we actually care
about is to make sure the pool can hold the minimum of required buffers.

GST_VIDEO_FRAME_PLANE_STRIDE() should be used to get the actual buffer stride,
as reported in the buffers's GstVideoMeta, when copying data to that buffer.

Modified to use gstglmemoryegl to avoid texture creation/copy operations
at the glupload.

Without this commit the decoder streaming thread stops without ever attending
the drain request, leaving the decoder input thread waiting forever.

Instead of the videodecoder one. The OMX video decoders have their
valid input in the template pad, so just check against that to
avoid doing a query downstream.
Interlaced stream could make the decoder use two input frames to produce
one output frame causing the gstvideodecoder frame list to grow.
Assuming the video decoder output frame in display order rather than in
decoding order, this commit add a way to release frames with PTS less
than current output frame.

Previously when using gst EGLImage allocator the caps was
video/x-raw, format=RGBA instead of
video/x-raw(memory:EGLImage), format=RGBA
Kepp previous behavior in case negotiation fails with caps feature.
It means it will still have a chance to use EGLImage even if the
feature is not in the caps.

Identical functionality spread of two different components.
We can't use a common base class because of different inheritance,
but let's try to share the code anyway.

No need to make it more complicated and error prone than
necessary. Also give the function a gst_omx_video_dec prefix
to distinct it from the encoder function.
