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.

The AV1 codec needs to support the film grain feature. When the film
grain feature is enabled, we need two surfaces as the output of the
decoded picture, one without film grain effect and the other one with
it. The first one acts as the reference and is needed for later pictures'
reconstruction, and the second one is the real display output.
So we need to attach another aux surface to the gst buffer/mem and make
that aux surface as the target of vaBeginPicture.

In 6ae24948 the pipeline buffer destroy were removing assuming it
wasn't required. Nonetheless, debugging the code it looks like a
buffer leak in iHD driver since the ID of the buffer kept increasing.
The difference now is that first the filter buffers are destroy first
and later the pipeline buffer.

Just like the decoder, the vapostproc also needs to copy the output
buffer to raw buffer if downstream elements only supports raw caps
and does not support the video meta.
The pipeline like:
gst-launch-1.0 filesrc location=xxxx ! h264parse ! vah264dec ! \
vapostproc ! capsfilter caps=video/x-raw,width=55,height=128 ! \
filesink location=xxx
needs this logic to dump the data correctly.

Both wasapi2 and wasapi plugins use WASAPI API. So "device.api=wasapi"
would make sense for the wasapi2 plugin as well. But people would be
confused by the identical "device.api=wasapi" property if intended
plugin is wasapi, not wasapi2. This change will make them distinguishable
by using "device.api" device property.

The first time update_src_caps is called, there's no frame parsed yet,
therefore we don't know whether the file has alternate-field interlacing
mode. If we run it again after we have a frame, it might be that now we
have the SEI pic_struct parsed, and therefore we know that it's
field-based interlaced, and therefore the height must be multiplied by
two. Earlier on this was not detected as a change.

One problem that va dmabuf allocator had is when preparing a buffer from
dmabuf memories in the allocator pool, specially when a buffer is composed by
several memories. This memories have to be by certain number and in certain
order.
This patch stores the number of memories and their address in order when a
dmabuf-based buffer is created and when preparing a buffer, it is reconstructed
with this info.
Finally, instead of pushing the memories as soon as they are unrefed, they are
hold until GstVaBufferSurface's ref_mems_count reaches zero (all the memories
related with that buffer/surface are unrefed). Until that happen, all the
memories are pushed back into the queue, locked, assuring that all the memories
related with a single buffer (with the same surface) remain contiguous, so the
buffer reconstruction is assured.

Instead of removing memories from buffers at reset_buffer()/release_buffer() the
bufferpool operation is kept as originally designed, still the allocator pool is
used too. Thus, this patch restores the buffer size configuration while removing
release_buffer(), reset_buffer() and acquire_buffer() vmethods overloads.
Then, when the bufferpool base class decides to discard a buffer, the VA
surface-based memory is returned to the allocator pool when its last reference
is freed, and later reused if a new buffer is allocated again.

Add a new element d3d11deinterlace to support deinterlacing.
Similar to d3d11videosink and d3d11compositor, this element is
a wrapper bin of set of child elements including helpful
conversion elements (upload/download and color convert)
to make this element configurable between non-d3d11 elements.
