05b9a89ed7 threads: fix old frames returned after avcodec_flush_buffers()
Calling avcodec_flush_buffers() and then avcodec_decode_video2() with
a 0-sized packet (to get remaining buffered frames) could incorrectly
return an old frame from before the avcodec_flush_buffers() call. Add
a loop in ff_thread_flush() to zero the got_frame field of each thread
to ensure the old frames will not be returned.

b12d217339 threads: limit the number of automatic threads to MAX_AUTO_THREADS
The extra thread added in {frame_}*thread_init was not taken into
account. Explicitly sets thread_count to 1 if only one CPU core was
detected. Also fixes two typos in comments.

b4d44a45f9 threads: introduce CODEC_CAP_AUTO_THREADS and add it to libx264
Some external codecs have their own code to determine the best number
of threads. This number is not necessary the number of cpu cores.
Thread_count will be only 0 if the codec has CODEC_CAP_AUTO_THREADS.

Can act as fallback and should work on a couple of Unix systems.

937ff3a18a threads: always include necessary headers for number of CPUs detection
Since the conditions for the actual usage are more specific a less
preferred method can be used. This would cause compilation errors
because necessary headers are not included.
