Automatic update of common submodule

From bcb1518 to 211fa5f
shapewipe: Send initial events after setting the elements to PLAYING

Otherwise we send them too early, and setting the elements to PLAYING
afterwards will drop all the events again.
po: Update translations
Update .po files
Release 1.3.1
Back to development
rtpsession: Keep local conflicting addresses in the session

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.
v4l2: Cleanup plugin registration

There is no plan to introduce special sources for jpeg, te v4l2src works fine
for this.

v4l2videodec: Simplify sub-instanciation mechanism

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.

v4l2: Add a common device enumerator

This will allow removing code duplication (hence bugs duplication).

v4l2: Use single pass iterator for M2M probe

Instead of having each M2M class do their own probing, use the
GstV4l2Iterator and probe all devices in a single pass.

v4l2devicemonitor: Port to use GstV4l2Iterator

pulsedevicemonitor: pa_subscription_event_t are enums, not flags

Coverity 1195132
pulsedevicemonitor: Index are per facility, not global

So need to keep the type of device in the device object
rtpjitterbuffer: avoid stall by corrupted seqnum accounting
rtpmux: Always let upstream chose the ssrc if it wishes
rtprtxreceive: Wait until timeout to clear association requests

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.
rtpaux/rtprtx: Make tests non-racy

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

v4l2: minor fix for closing the fd

The fd returned by open() could theoretically be 0 as well.

Coverity CID 1211823.
matroskamux: ensure we don't dereference a NULL pointer

while working out the codec ID.
