If the driver supports it (iHD, so far) and the parameter -d is set,
the direction of the video will be changed randomly.
In the code you can select, at compilation time, if the direction
change is done by element's property or by pipeline events.

Added helper function _update_passthrough() which will define and set
the pass-through mode of the filter, and it'll either reconfigure both
pads or it will just mark the src pad for renegotiation or nothing at
all.
There are cases where both pads have to be reconfigured (direction
changed, for example), other when just src pad has to (filters
updated) or none (changing to ready state).
The requirement of renegotiation depends on the need to enable/disable
its VA buffer pools.
This patch sets pass-through mode by default, so the buffer pools
aren't allocated if no filtering/direction operations are defined,
which is the correct behavior.

For the time being the GstPlayer library remains as a wrapper for GstPlay, in
order to keep existing applications working and give them time to port to
GstPlay. GstPlayer will remain in -bad for a couple cycles and the plan for
GstPlay is to move it to -base before 1.20.

This aims to be a replacement for the GstPlayer library. In GstPlay, notifications are
sent as application messages through a dedicated GstBus. The GMainContext-based
signal dispatcher was replaced by a GObject signal adapter, now relying on the
bus to emit its signals. The signal dispatcher is now optional and fully
decoupled from the GstPlay object.

It was possible to generate a SDP that had an RTX payload type
that matched one of the media payload types when providing caps via
codec_preferences without any sink pads.

Especially specify the field-order in the interleaved mode. Otherwise it
might cause the negotiation to fail, because
GST_PAD_SET_ACCEPT_INTERSECT is not set on the sinkpad, and the
field-order is missing in the sink template but can be present in the
outside caps.

... instead of the largest we ever seen.
Note that d3d11h264dec element holds previously configured DPB size
for later decoder object re-open decision.
This is to fix below case:
1) Initial SPS, required DPB size is 6
- decoder object is opened with DPB size 6
- max_dpb_size is now 6
2) SPS update with resolution change, required DPB size is 1
- decoder object is re-opened with DPB size 1
- max_dpb_size should be updated to 1, but it didn't happen (BUG)
3) SPS update without resolution change, only required DPB size is updated to 6
- decoder object should be re-opened but didn't happen
because we didn't update max_dpb_size at 2).

The new H.264 uAPI requires that all drivers support
scaling matrix only as an option, when a non-flat
scaling matrix is provided in the bitstream headers.
Take advantage of this and avoid passing the scaling
matrix if not needed.

Frame-based decoding mode doesn't require SLICE_PARAMS and
PRED_WEIGHTS controls.
Moreover, if the driver doesn't support these two controls, trying
to set them will fail. Fix this by only setting these on
slice-based decoding mode.

To convert decoded texture into other format, downstream would use
video processor instead of shader. In order for downstream to
be able to use video processor even if we copied decoded texture
into downstream pool, we should set this bind flag. Otherwise,
downstream would keep switching video processor and shader
to convert format which would result in inconsistent image quality.

default min port == 0, max port == 65535 -- if min port == 0, uses existing random port selection (range ignored)
add 'gathering_started' flag to avoid changing ports after gathering has started
validity checks: min port <= max port enforced, error thrown otherwise
include tests to ensure port range is being utilized (by @hhardy)

We can only have 1 single GstTranscoderSignalAdapter object for a
given GstTranscoder object, this enforces that by avoiding to expose
a constructor and instead add a method to GstTranscoder to get the
signal adapter (internally creating it when needed). We can still
cleanly ensure that the signal adapter is running for the requested
GMainContext and return NULL if it is not the case.
