28096e0a80 h264: wait for initial complete frame before outputing frames 
This can be optionally disabled whith the "output_corrupt" flags
option.  When in "output_corrupt" mode, incomplete frames are
signalled through AVFrame.flags FRAME_FLAG_INCOMPLETE_FRAME.

62844c3fd6 h264: Integrate clear_blocks calls with IDCT 
The non-intra-pcm branch in hl_decode_mb (simple, 8bpp) goes from 700
to 672 cycles, and the complete loop of decode_mb_cabac and hl_decode_mb
(in the decode_slice loop) goes from 1759 to 1733 cycles on the clip
tested (cathedral), i.e. almost 30 cycles per mb faster.

05fa79b844 hwaccel: fix use with frame based multithreading 
Allows use of AVHWAccel based decoders with frame based multithreading.
The decoders will be forced into an non-concurrent mode by delaying
ff_thread_finish_setup() calls after decoding of the current frame
is finished.

This wastes memory by unnecessarily using multiple threads and thus
copies of the decoder context but allows seamless switching between
hardware accelerated and frame threaded software decoding when the
hardware decoder does not support the stream.

0b499c9b06 h264: Make it possible to compile without error_resilience 
Error resilience is enabled by the h264 decoder, unless explicitly
disabled. --disable-everything --enable-decoder=h264 will produce
a h264 decoder with error resilience enabled, while
--disable-everything --enable-decoder=h264 --disable-error-resilience
will produce a h264 decoder with error resilience disabled.

a157c7f2b8 h264: fix bit depth changes with frame threading 
AVCodecContext.bits_per_raw_sample is updated from the previous thread
in the generic update function before the codec specific update_thread
function is called. The check for reinitialization of dsp functions uses
bits_per_raw_sample. When called from update_thread_context it will be
already at the current value and the dsp functions aren't updated if
only the bit depth changes.

9c9ede44f3 h264: allocate hwaccel privdata after the frame buffer 
This ensures the hwaccel privdata does not leak when a frame buffer could
not be allocated (and toggle the assert when the frame is re-used).
Having no frame buffer available is quite common when using the DXVA2
hwaccel in situations where the DXVA2 renderer is being re-allocated, for
example when moving between displays.
