... as sender should keep track of segment base accumulation.
Rather, it may have some adverse effects as a spurious segment event,
e.g. in collectpads.
Try to avoid using the request-pt-map to get caps but set them directly
on the udpsrc element. That way, the caps get nicely transformed as they
pass through the different elements in the rtpbin, including the AUX and
decoder/encoder elements.
Protect caps with the lock.
Don't push the caps event from the set_property function but mark the
pad for reconfiguration so that it will renegotiate and push the new
caps event in the streaming thread.
We should open the socket when going to NULL<->READY and not in the
start/stop vemthod, which is called in READY<->PAUSED. This makes it
possible to allocate a socket without going to PAUSED (and starting the
negotiation).
Adds type compatiblity with other OS like BSD. This uses types mapping macro to
avoid conflict with existing defined types. We resuse glib types as these are
already available on supported platforms. This is GCC only because of the
le32 type that uses bitwise attribute.

The checks were removed inadvertedly in previous patch and not replaced.
Re-introduce the configure checks and some of the checks in order to enable
this plugin again. We only check if videodev2.h exist on the platform to
avoid building on Windows or OSX, though we build against our own copy. This
was breaking the build on built-bot.
With years the amount of ifdef have grown up and we are not even sure if the
old code path compiles. Each time we need to update the v4l2 framework to add
the new feature, we break compilation on older kernel. With exception of two
controls in the video orientation control, this patch get rid of all ifdef by
including the latest version of videodev2.h inside GStreamer.

Instead the queued buffer might have an old caps while the pad
is already storing the information for a new caps. Mixing those
while handling buffers will often lead to issues

V4L2 kernel drivers allow configuration of the hardware settings via a
mechanism called controls. These can be referred to by name such as
"Brightness" and "White Balance Temperature". The user-space command line
client for setting these controls (v4l2-ctl) normalises these names such
that they only contain lower case alphanumeric characters and the
underscore '_'. e.g:
Kernel v4l2-ctl
----------------------------------------------------
Brightness brightness
White Balance Temperature white_balance_temperature
Focus (absolute) focus_absolute
GStreamer seems to want to follow this pattern but failed for controls with
more than one consecutive non-alphanum character. e.g. GStreamer would
produce "focus__absolute_" rather than "focus_absolute".
This commit fixes that issue. Backwards compatibility is preserved by
normalising all control names before comparison.

Only return EOS the next time create() is called, if at all. basesrc
should already take care of not calling it again.
Also always return immediately if the previous flow return was
not OK. This indicates an error somewhere.
Remove caps restrictions that correspond to the default and are not
required in SDP. With the new usage of having pads require a subset
of the caps, they will make the negotiation fail.
The "encoding-params" is optional in the SDP, because we now require
a subset of the caps, it would fail caps negotiatioin if it wasn't present.
So removed it from the template caps.
Keep track of what streams we did the SETUP for. We only need to
configure caps, wait for pads and push events on setup streams. We can
remove the disabled state of the stream and simplify some checks.
After we setup a stream, skip the other streams that have the same
control url. Use a skipped flag to mark streams that should be skipped.
