The OMX stack of the zynqultrascaleplus (the only one supporting
NV12_10LE32 and NV16_10LE32) will now pick the proper profile if none
has been requested. Best to rely on its default than hardcoding a
specific one in gst-omx.

0xffffffff is the magic number in gst-omx meaning 'the default value
defined in OMX'. This works fine with OMX parameters which are only set
once when starting the component but not with configs which can be
changed while PLAYING.
Save the actual OMX default bitrate so we can restore it later if user
sets back 0xffffffff on the property.
Added GST_OMX_PROP_OMX_DEFAULT so we stop hardcoding magic numbers
everywhere.
https://bugzilla.gnome.org/show_bug.cgi?id=794998
We weren't using the usual pattern when re-setting the bitrate:
- get parameters from OMX
- update only the fields different from 0xffffffff (OMX defaults)
- set parameters
Also added a comment explaining why we re-set this param.

- Report the error from OMX if any (OMX_EventError)
- If not report the failing to the application (GST_ELEMENT_ERROR)
- return GST_FLOW_ERROR rather than FALSE
- don't leak @frame

We already have the exact same message at the beginning of
gst_omx_video_enc_handle_frame(). Having it twice is confusing when
reading/grepping logs.
I kept the earlier one to keep the symetry with
gst_omx_video_dec_handle_frame().

Check input buffers for ROI meta and pass them to the encoder by using
zynqultrascaleplus's custom OMX extension. Also add a new
"default-roi-quality" in order to tell the encoder what quality level
should be applied to ROI by default.

The 'target-bitrate' property can be changed while PLAYING
(GST_PARAM_MUTABLE_PLAYING). Make it thread-safe to prevent concurrent
accesses between the application and streaming thread.

I spent quiet some time figuring out why performance of my pipeline were
terrible. Turned out it was because of output frames being copied
because of stride/offset mismatch.
Add a PERFORMANCE DEBUG message to make it easier to spot and debug from logs.

The OMX specs defines 8 headers that implementations can use to define
their custom extensions. We were checking and including 3 and ignoring
the other ones.
https://bugzilla.gnome.org/show_bug.cgi?id=792043
We are now always checking which files are present or not, even when using our
internal copy of OMX, rather than hardcoding the ones present in it.

It seems cleaner to use the proper meson tools to include this path
rather than manually tweak the build flags.
This also allows us to simplify the OMX extensions detection code. We
are now always checking which files are present, even when using our
internal copy of OMX, rather than hardcoding the ones present in it.

This hack tries to pass as much information as possible from caps to the
decoder before it receives any buffer. These information can be used by
the OMX decoder to, for example, pre-allocate its internal buffers
before starting to decode and so reduce its initial latency.
This mechanism is currently supported by the zynqultrascaleplus decoder.
https://bugzilla.gnome.org/show_bug.cgi?id=792040
I find it confusing when debugging that OMX calls returning an error
where not logged as GST_LEVEL_ERROR making them harder to spot.
Fix this by introducing simple log macros checking the return value of
the OMX call and logging failures as errors.

The Zynq UltraScale+ encoder implements a custom OMX extension to
directly import dmabuf saving the need of mapping input buffers.
This can be use with either 'v4l2src io-mode=dmabuf' or an OMX video
decoder upstream.

Make use of the new GstVideoEncoder QoS API to drop late input frames. This may
help a live pipeline to catch up if it's being late and all frames end up
being dropped at the sink.

If something goes wrong while trying to manually copy the input buffer,
the 'break' was moving us out of the 'for' loop but not out of the switch block.
So we ended up calling gst_video_frame_unmap() a second time (raising
assertions) and returning TRUE rather than FALSE.
Reproduced with a WIP zynqultrascaleplus OMX branch reporting wrong
buffer sizes and so triggering this bug.

If less than 1%.
The dynamic format change should not happen when the
resolution does not change and when only the framerate
changes but very slightly, i.e. from 50000/1677=29.81
to 89/3=29.66 so a "percentage change" of less than 1%
(i.e. 100*(29.81-29.66)/29.66 = 0.50 < 1 ). In that case
just ignore it to avoid unnecessary renegotiation.
https://bugzilla.gnome.org/show_bug.cgi?id=759043
If the OMX component supports dynamic buffer mode and the input buffers
are properly aligned avoid copying each input frame between OMX and
GStreamer.
Tested on zynqultrascaleplus and rpi (without dynamic buffers).
