ad6ea8fbe9 mpegpsmux: put stream headers into output caps 
Basic version with only the system header and the program
stream map. An advanced version could include codec-specific
bits like SPS/PPS too. This is useful in connection with
e.g. multifilesink to make sure new files always start with
the stream headers.

eaeba16a56 mpegpsmux: add "aggregate-gops" property to aggregate GOPs into buffer lists 
Useful in connection with multifilesink, for example, to make sure
the new file always starts with a keyframe.

f40ccb3811 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.

b48b3c2c86 opus: properly create channel mapping tables 
There are two of them, unintuitively enough; the one passed
to the encoder should not be the one that gets written to the
file. The former maps the input to an ordering which puts
paired channels first, while the latter moves the channels
to Vorbis order. So add code to calculate both, and we now
have properly paired channels where appropriate.

09f0860a10 mpegtsdemux: only offset timestamps when live 
This code is to sync to a live source when there is a delay
between start and when we receive the first buffer, so it does
not make sense in a non live case.

This fixes playback of streams where the input timestamps are
based off some arbitrary offset.

780d774a5d rsndec: Don't use the initial-identity property on autoconvert

dcf04269e1 autoconvert: Remove the initial-identity property from autoconvert 
Initially creating an identity element to forward serialized
events downstream before any caps are known is broken behaviour.

Serialized events should only be forwarded downstream if the
caps are already known, otherwise autopluggers and other elements
using pad-blocks will fail.

This behaviour also doesn't work anymore after basetransform
was fixed to queue serialized events until the caps are known
as a result of fixing bug #659571.

See bug #599469, #665205.

c4d987b6d3 codecparsers: Variant of _identify_nalu without checks 
This is useful for cases where the caller *knows* that the provided
input contains a whole NALU and can therefore avoid:
* the expensive checks for the next start code (which won't be present)
* delaying the input parsing (since we would need the next incoming NALU
  in order for the parsing code to detect the next start code)
