rtpqcelpdepay: Remove uneeded variable
y4mencode: Remove dead code

set/get property isn't used
rtpsession: allow setting internal-ssrc again
gstrtpsession: suggest upstream to use the new "internal-ssrc" after a collision

When a collision is found on the internal ssrc, we have to change it.
Ideally, we want also the payloader upstream to follow this change and use
the new internal ssrc. Ideally we want this condition to be always met:
if there is one payloader sending on this session, its ssrc should match the
internal ssrc.
wavparse: emit midi-base-note tag from data in 'smpl' chunk

Add parsing of the 'smpl' chunk. Right now we only grab the midi-base-note and
emit it as a tag.
rtpbin: request-rtp-encoder are no action signals

The request-rtp-encoder signals are not action signals so mark them
correctly and use an accumulator to collect the result value.
rtpbin: expect the pads on the encoders

Don't use request pads for the encoder elements, the signal handler
should request the pads and make sure they are available with the right
name.
tests: fix leak
rtpbin: fix memory leaks
tests: add unit test for encoder element
rtpbin: handle multiple encoder instances

Keep track of elements that are added to multiple sessions and make sure
we only add them to the rtpbin once and that we clean them when no
session refers to them anymore.
rtpbin: add signal for new jitterbuffer

Emit a signal when a new jitterbuffer is created so that the app can
have a chance to configure it.
rtpbin: add Since tags
rtpsession: internal-ssrc is no longer deprecated
rtpvrawpay: Add missing break

COVERITY CID 1139762
avimux: Add missing break

I guess no-one noticed we no longer could mux WMV3 ...

osxvideosink: Fix build on updated OS X Leopard

osx: Make OSX version checks more consistent

And especially also consider update versions, e.g. 10.5 with updates
will be 1051 or similar and thus bigger than MAC_OS_X_VERSION_10_5 but
still won't have the API we want to use.
wavparse: Skip id3 tag

Skip id3 tag during wav parse.

rtpbin: make request_element method internally

We can use the same method to create encoder and decoder elements, they
are just internal elements that we create.
