5fa3325335 rtpopuspay: set MARKER flag 
Set MARKER flag on first buffer after DTX.

According to RFC 3551 section 4.1 the marker bit needs to be set on
"the first packet after a silence period during which packets have
not been transmitted contiguously".

b9ed5c7fa0 rtpopuspay: support libwebrtc-compatible multichannel payload 
When the audio has more than 2 channels, add optional fields to output
caps from which webrtcbin can generate SDP in the syntax recognized by
"multiopus" codec present in libwebrtc [1].

e.g. for 5.1 audio:

a=rtpmap:96 multiopus/48000/6
a=fmtp:96 num_streams=4;coupled_streams=2;channel_mapping=0,4,1,2,3,5

d9aaa15a30 rtpopuspay: make depay ! pay work 
There is a use-case for a server to re-payload opus going through it.

Problem was that the payloader requires channels in the caps, but
this is not something the depayloader can parse out of the stream, meaning
caps-negotiation would fail.

Removing the requirement of channels in the template-caps fixes this.

2b11c62571 rtppayload: Fix VP8/VP9/OPUS dual encoding name handling 
All these were copy pasted and would lead to assertion when chained with
rtpmux. This commit rewrite the negotiation with downstream. This also
drop the fallback to ancient names if the pad is unlinked. This was
completly arbitrary decision that made no sense.

f9a740b319 rtp: opus: use existing utility funcs for copying/dropping metas 
We had our own copies of those while the code was in -bad, but now
we can use the existing utility functions instead of re-implementing
them.

0472d9f8b2 opus: Copy metadata in the (de)payloader, but only the relevant ones 
The payloader didn't copy anything so far, the depayloader copied every
possible meta. Let's make it consistent and just copy all metas without tags or
with only the audio tag.

8df374108a opusenc: add upstream negotiation for multistream ability 
This will help elements that cannot deal with multistream,
such as the RTP payloader.

The caps now do not include a "streams" field anymore, but
a "multistream" boolean, since we have no real use for knowing
the exact amount of streams.
