Remove some redundant operations (convubw) and use the correct variable,
t2, in the orc_overlay_bgra function.

GCC 4.6.x spits warnings about variables that are set but unused. Such
variables have been removed in blend, collectpads2 and videomixer2.

for informational purposes in some cases.

gst_rtp_session_chain_recv_rtcp () was changed in commit 490113d4
to always return GST_FLOW_OK instead of the return value of

Also clean up advancing of the data pointer a bit.

Fixes bug #647659.

This is needed for automatic transcoding using encodebin. Our typefinder
does not always add a variant to the found caps, and encodebin needs
an *exact* match to the caps on the source pad template, so we need
to add the variant-less video/quicktime caps to the template as well
for encodebin to be able to find it. Add unit test for this as well.
