This only adds a subset of the frame rates that can be stored, a full list
would be more than 500 entries. Such full list could (and should) be added
if it has a usecase but the number of users of even the now added rates
seem rather small.

Discontinuous transmission is an addition to VAD/VBR operation, that
allows to greatly reduce bitrate for silent chunks or stationary
noises.

The value used in allocation is based on a estimate of the
maximum size of the spectral coefficients multiplied with 2
and rounded up. The exact or a tighter limit should be
found and used instead. But this issue shouldnt be left
open until someone works on that.

Right now it incorrectly assumes that the frames are sent in the proper
order, which worked with old ffmpeg and avconv versions by accident.

Output frames correspond 1:1 to input frames on the main input.
So use the main input timebase for output.

Right now the buffer is zeroed, which does not represent silence for U8(P).

AVFrame.extended_data has to reset to the AVFrame.data of the current
thread context after copying the frame contents.
Fixes crashes with frame-threading after 2bc0de38.

When initialized as stereo, libspeex can decode either mono or stereo packets
and will output stereo.

If there is no extradata and the sample rate given by the user is not valid,
decode as ultra-wideband.

otherwise a unexpected timebase could be choosen
that is one that is thousand times more precisse than requested
which can have sideeffects.
