ee723996db opusenc: bound the bitrate to more sensible values 
Go from the bounds mentioned in the spec, and allow some more
variation.
In particular, don't allow silly low bitrates, and allow reaching
the maximum useful bitrate.

bb39c86fdf opusenc: fix crash on pathological parameters 
Asking for 1 bit/s would select a 0 byte buffer, leading
to a crash. Buffer size is now controlled by a max-payload-size
property, which can't be less than 2.

95ae14f8b4 opusenc: do not push header buffers 
Opus headers appear only when muxed in Ogg, so only place them
on the caps, where oggmux will find them, but other elements will
be blithely unaware of them.

7030b04f5e opus: make opusparse set headers on caps 
Header-on-caps code moved to a new shared location to avoid
duplicating the code.

ccc04a1529 opusenc: do not include variable fields in caps 
Those can vary from one packet to the next, so have no reason
to be in the caps.

8bb91f923f opusparse: add opusparse element 
A very simple element that parses Opus streams from the ad hoc
framing used by the Opus test vectors.

310daa5096 opusdec: allow negotiation of rate/channels with downstream 
Since an opus stream may be decoded to any (sensible) rate,
and either stereo or mono, we try to accomodate downstream.

ffc4408d53 opusdec: rewrite logic 
Parameters such as frame size, etc, are variable. Pretty much
everything can change within a stream, so be prepared about it,
and do not cache parameters in the decoder.
