4df2ffaad6 opusenc: Encode exactly the amount of samples we got as input and put correct timestamps on it
The first frame has lookahead less samples, the last frame might have some
padding or we might have to encode another frame of silence to get all our
input into the encoded data.

This is because of a) the lookahead at the beginning of the encoding, which
shifts all data by that amount of samples and b) the padding needed to fill
the very last frame completely.

Ideally we would use LPC to calculate something better than silence for the
padding to make the encoding as smooth as possible.

With this we get exactly the same amount of samples again in an
opusenc ! opusdec pipeline.

fe6a1d5b88 opusenc: update output segment stop time to match clipped samples
This will let oggmux generate a granpos on the last page that properly
represents the clipped samples at the end of the stream.

ad4da8dd0e opus: set author to myself, and update copyright notices
because as slomo noted, in fact pretty much all the code in there is mine.

f807905786 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.

670c365400 opus: switch to multistream API
It's very similar to the basic API, and is a superset ot it,
which will allow encoding and decoding more than 2 channels.

b226e8a085 opusenc: allow setting most properties at PLAYING time
Opus allows these to be changed during encoding, transparently
to the decoder.

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.

Copy the celt plugin and convert it to Opus.  Mostly works.
