10b77fbf0d avcodec/mips: Split uni mc optimizations to new file
This patch moves HEVC code of uni mc cases to new file hevc_mc_uni_msa.c.
(There are total 5 sub-modules of HEVC mc functions, if we add all these modules in one single file, its size would be huge (~750k) & difficult to maintain, so splitting it in multiple files)
This patch also adds new HEVC header file libavcodec/mips/hevc_macros_msa.h

9ae766d1c6 avcodec/vdpau: Re-factor pre-hwaccel helper functions into separate header
h264.h and hevc.h are mutually exclusive due to defining some of the same
names. As such, we need to avoid forcing h264.h to be included if we want
hevc decode acceleration to be possible.

However, some of the pre-hwaccel helper functions need h264.h. To avoid
messy collisions, let's move the declaration of all those helpers to
a separate header which we will exclude for the hevc support (which will
be hwaccel-only).

e48a9ac9af libshine: fix support for shine 3.0
shine_encode_buffer expects written to be an int pointer, while the
previous shine_encode_frame expected it to be a long pointer.

Thus encoding with libshine currently always fails with
"internal buffer too small", because a negative return value of
shine_encode_buffer is interpreted as a very large long value.

02cf59f3a6 WebP encoder: use WebPAnimEncoder API when available.
WebPAnimEncoder API is a combination of encoder (WebPEncoder) and muxer
(WebPMux). It performs several optimizations to make it more efficient
than the combination of WebPEncode() and native ffmpeg muxer.

When WebPAnimEncoder API is used:
- In the encoder layer: we use WebPAnimEncoderAdd() instead of
  WebPEncode().
- The muxer layer: works like a raw muxer.

On the other hand, when WebPAnimEncoder API isn't available, the old code is
used as it is:
- In the codec layer: WebPEncode is used to encode each frame
- In the muxer layer:  ffmpeg muxer is used

3efe0393e4 hevc: make avcodec_decode_video2() fail if get_format() fails
Personally, I need the decoder to back out if get_format() returns no
usable pixel format. This didn't work because the error code was not
propagated down the call chain. This in turn happened because the
variable declaration removed in this patch shadowed the variable, whose
value is returned at the end of the function. Consequently, failures of
decode_nal_unit() were ignored in this place.

eafbc6716c vmnc: Delay pixel size check
Some clients incorrectly set 24 as bits_per_coded_sample, while
the actual value is preserved in one of the codec headers.
In order to work around this, delay the check until decode_frame().

b012bd5068 libavcodec/x265: detect csps in libx265_encode_init_csp()
Without this change, if you link with an 8bit libx265 and try to specify
a 10bit input color space via:

  ffmpeg -i in.mov -c:v libx265 -pix_fmt yuv420p10le out.mp4

It will error with:

  Incompatible pixel format 'yuv420p10le' for codec 'libx265',
  auto-selecting format 'yuv420p'

With this fix, it will learn if a 10bit libx265 is available at startup,
and thus allow 10bit input color spaces.

If we find a second non-sub8x8 motion vector for a non-first sub8x8
block, and the clamped value is identical to the first non-sub8x8

zero.

libvpx (probably accidentally) clears the bits if error_res is set,
along with keyframe/intraonly. This probably wasn't the intention
(since it's local data), but it's behaviour we have to copy...
