      jrev/xvid: hardcode use of C put/add_pixels_clamped. · 32baeafe
      Ronald S. Bultje authored 
      This removes the last use of the ff_put/add_pixels_clamped global
function pointers, and as such they are removed.

This patch has a negative effect on performance on MIPS, since there's
a SIMD-optimized put/add_pixels_clamped, but no xvid or jrev. From a
code maintenance point of view, that is probably acceptable.

Because the global function pointers are removed, this fixes the following
tsan warnings when running e.g. fate-dnxhr-parse:

      x86/simple_idct: add explicit sse2 simple_idct_put/add versions. · e0c20567
      Ronald S. Bultje authored 
      These use the mmx IDCT, but sse2 put/add_pixels_clamped implementations.
This way we don't need to use the ff_put/add_pixels_clamped function
pointers.

      cavs: add a sse2 idct implementation. · 2f0591cf
      Ronald S. Bultje authored 
      This makes using the function pointer ff_add_pixels_clamped() unnecessary,
since we always know what the best implementation is at compile-time.

      x86/xvididct: remove use of ff_put/add_pixels_clamped function pointer. · b51d7d89
      Ronald S. Bultje authored 
      Since there's separate SSE2 implementations of xvid_idct_put/add, this
patch has no practical impact on performance.

      idct_arm: remove use of ff_put/add_pixels_clamped function pointer. · 40cbd686
      Ronald S. Bultje authored 
      Instead, hardcode the use of the _arm implementation of add_pixels,
and use the C version for put_pixels (as no arm-optimized version
exists). Since there's separate implementations of idct{,_put,_add}
for neon, this has no practical impact on performance.

      pthread_frame: allow per-field ThreadFrame owners. · 083300be
      Ronald S. Bultje authored 
      This tries to handle cases where separate invocations of decode_frame()
(each running in separate threads) write to respective fields in the
same AVFrame->data[]. Having per-field owners makes interaction between
readers (the referencing thread) and writers (the decoding thread)
slightly more optimal if both accesses are field-based, since they will
use the respective producer's thread objects (mutex/cond) instead of
sharing the thread objects of the first field's producer.

In practice, this fixes the following tsan-warning in fate-h264:
