...
This fixes a failing assert in ff_raw_read_header (in
fate-g722dec-1), where bits_per_coded_sample is set using this
function and is required to have a positive value.

pthread: validate_thread_parameters() ignored slice-threading being intentionally off
...
The thread_type API allows you to request only FF_THREAD_FRAME (instead of
FRAME | SLICE), but it was being ignored.
We don't implement both of them at the same time, so there isn't an effect
on current codecs, except that you can request no kinds of threading now
(a bit useless).

Remove unnecessary parameter from ff_thread_init() and fix behavior

thread_count passed to ff_thread_init() is only used to set AVCodecContext.
thread_count, and can be removed. Instead move it to the legacy implementation
of avcodec_thread_init().
This also fixes the problem that calling avcodec_thread_init() with pthreads
