Merged without changing the strict_std_compliance check, as it breaks FATE
and changes decoding behavior.

This adds a computation of the progress speed versus realtime ("Nx")
to the status line and to the report log. It uses the progress time
as already calculated for total output time as a base.

Due to this typo max_center can be too large, causing nlsf to be set to
too large values, which in turn can cause nlsf[i - 1] + min_delta[i] to
overflow to a negative value, which is not allowed for nlsf and can
cause an out of bounds read in silk_lsf2lpc.

These postfixes can be computed statically, and there is no need to
waste runtime resources.

A negative codec_id cannot be handled by the found_decoder API of
AVStream->info: if the codec_id is not recognized, found_decoder is set
to -codec_id, which has to be '<0' according to the API documentation.

This can cause NULL pointer dereferencing in try_decode_frame.

Also make sure the codec_type matches the expected one for codec_id.
