cf39b461d3 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).

ba9ef8d04e 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
enabled did not set it since ff1efc524c.

This makes the AC3 encoder use the shared fixed-point MDCT rather
than its own implementation.  The checksum changes are due to
