Now that we might be copying out buffer (e.g. downstream don't support video
meta bug we need it) we need to move the EOS handling inside the process
method.
As soon a the alpha component can be set, we can expose the RGB32 and BGR32
format as ARGB and BGRA as long we can deterministically set the alpha padding
value.
In certain cases we cannot live without video meta and/or crop meta
being enabled in our internal buffer pool. Ensure this is always the case,
regardless of having support for allocation query.
Upon error, the pools might not have been allocated yet, hence we should not
try and flush them (even though we still want to make sure the processing thread
is fully stopped).
Buffer pool was guessing wrongly the number of planes rather
then reading the value from obj->n_v4l2_planes. This was causing
format YU12 (I420) to fail upon check.
The complex mechanic to try and choose the right thing did not work. Instead,
simply probe the non-contiguous format first and then the contiguous one.
This is in fact very low overhead, as there is a relatively small number of
pixel format supported by each devices.
Certain decoder has been found to not choose a format automatically. Running
v4l2videodec on these would assert. This patch will make it fail cleanly
instead.
If caps are set again, we have a risk od returning from set_format with a
input_state pointing to dead memory. Clearing the pointer after unref fix
this issue.
Uppon certain downstream error, stop() is called without a flush(). This mean that
the streaming thread may still be running even though unlock has been called.
Now calling flush to reset the decoder state if we are processing.
When we cancel connection attempts and similar things, there are still
some operations pending on our main context from the GCancellables. We
should let them all run before unreffing our context, otherwise we leak
file descriptors.
Unfortunately this requires libsoup 2.47.0 or newer as earlier versions
steal our main context from us and we can't use it for cleanup later
without assertions and funny crashes.

Fix the raciness by iterating on a condition instead of using the gmainloop.
Don't use the EOS as the target, otherwise the retransmission of the last
packets are lost. Also count the retranmissions requests that are dropped.
Check the condition before blocking on the GCond
https://bugzilla.gnome.org/show_bug.cgi?id=728501
If two streams request a retranmission for the same SSRC, ignore the second
one if the first oen is less than one second old, otherwise time out the first
one and ignore the second.
Simplify sub-instanciation by defining an absract type and using subtype
class and instance init callback. This also fixes a bug where the template
pads get initialized too late.

As we now replace the local RTPSource on a conflict, it's no longer possible
to keep local conflicts in the RTPSource, so they instead need to be kept
in the RTPSession.
Also fix the rtpcollision test to generate multiple collisions instead of
one by change the address, as otherwise we detected that it was a single one.
