Always initially use try_format(), delaying set_format() to when the
allocation is being negotiated. This avoid having two code paths, and
will be help adding support for properly importing buffers of specific
strides and offsets.

This is an enum not a boolean, and a value of 2 signals
that the video is progressive, but we would mistakenly set
interlace-mode=mixed on the output caps.

The desired colorimetry is logged with all parameters (colorpsace,
range, matrix, and transfer function), but of the values actually
set by the driver, only colorspace is logged. Complete the debug
log message to display all colorimetry parameters:
Desired colorspace is 8:1:1:1
Got format of 640x480, format YU12, nb planes 1, colorspace 8
->
Desired colorspace is 8:1:1:1
Got format of 640x480, format YU12, nb planes 1, colorspace 8:0:0:0

gstjpegdec sets 1:4:0:0 colorimetry (full range BT.601 YCbCr encoding
with unknown primaries and unknown transfer function). This currently
gets translated to bt601 or bt709 depending on resolution.
Both cases result in a negotiation failure:
ERROR: from element /GstPipeline:pipeline0/v4l2video0convert:v4l2video0convert0: Device '/dev/video0' does not support 1:4:0:0 colorimetry
Improve the guessing game by selecting JPEG colorimetry (JPEG colorspace
with sRGB transfer function) under these specific conditions, and loosen
the matching so that 1:4:0:0 input gets accepted if the device is
actually configured to 1:4:7:1 (V4L2_PIX_FMT_JPEG default).

Setting the priv field to a magic value stops V4L2 core from zeroing
the extended colorimetry fields quantization, ycbcr_enc, and xfer_func
for non-mplane queues.

This effectively (but optionally) requires libjpeg-turbo which
ships with a .pc file and is what pretty much everyone these days
uses anyway for libjpeg, so shouldn't be a problem hopefully.

On Linux, the kernel returns twice the size as it will allocate extra
space for accouting. We devides this value by two in order to ensure
that get/set value now match. This fixes the set buffer size validation
and allow having a nice warning when the size if surpassed and the
process does not have CAP_NET_ADMIN capabilities.

The udp buffer size is limited to a maximum of around 100K.
Some apps need to set the force bufsize for their own operation.
Use the SO_RCVBUFFORCE option in order to override the rmem_max limit
of linux kernel. Require user to have the CAP_NET_ADMIN privilege to
work.

rtph264pay and rtph265pay skip updating the parameter set timestamp if
the units they see contain no new configuration. This can result in
them injecting duplicate parameters.

The stream context was holding a reference to the
internal queue and pads, with pad probes that were
in turn holding references to the stream context.
This lead to a leak if the request pads weren't explicitly
released.

The input from an v4l2 device that was used the first time was
remembered for next times, and set again always the pipeline is
set to READY state. This was making that users wasn't able to
select a different input without having to create a new pipeline.
This patch makes that v4l2src element forget previous used input
when going to NULL state, so it will check again for the current
selected input when going again to READY state. Users can change
to NULL state, select a new input with a VIDIOC_S_INPUT ioctl
and change to PLAYING again.

All these were copy pasted and would lead to assertion when chained with
rtpmux. This commit rewrite the negotiation with downstream. This also
drop the fallback to ancient names if the pad is unlinked. This was
completly arbitrary decision that made no sense.

Pass through closed caption data when deinterlacing. When two
deinterlaced frames are created for the same interlaced frame (e.g.
fields=all), the second of the two frames will have no closed caption
data.
Also fixed memory leaks related to timecode meta pass-through.

This causes rtspsrc to send a teardown and wait on
PAUSED->READY transition, with a configurable delay.
Otherwise, typically teardown never gets sent in
playbin / uridecodebin where the transition back to NULL
happens too quickly.
The timeout is set to 100ms default.
