Since commit 676a395a aac->frame->data is not necessarily allocated at
the end of aac_decode_frame_int if avctx->channels is 0.
In this case a bogus frame without any data, but non-zero nb_samples is
returned.

The previous version checked for 14-bit streams and did not properly
work across buffer boundaries.
Use the 64-bit parser state to make extended sync word detection work
across buffer boundary and check the extended sync word for 16-bit LE
and BE core streams to reduce probability of alias sync detection.

ffmpeg can now use the x265 multi-library interface to make a runtime
selection between a number of libx265 libraries (perhaps 8bpp and 16bpp).
ffmpeg will link to one build of libx265 (statically or
dynamically) and this linked version of libx265 will support one
bit-depth (8 or 10 bits). At runtime, ffmpeg now has the option to request the
encoder to use a different bit depth(8 or 10). If the requested bitdepth
is zero, or if it matches the bitdepth of the system default libx265 (the
currently linked library), then this library will be used for encode.
If ffmpeg requests a different bit-depth, the linked libx265 will attempt
to dynamically bind a shared library with the requested bit-depth from the install
location (default or user-specified).
new x265 API:
const x265_api* api = x265_api_get(int bitDepth);
x265_api - holds the libx265 public API functions
bitDepth - requested API for 8bpp or 16bpp
note: Use 0 to indicate native bit depth of the linked libx265 and
x265_api_get(0) is guaranteed to return a non-null pointer

No real difference in quality, its a bit slower for the same dia_size as more
vectors are searched for the same dia_size

If in compression mode rice_limit = 0 leads to call
`show_bits(gb, k)` in `decode_scalar` with k = 0.
Request a sample in case it is valid and it should be accepted.

AV_PIX_FMT_GRAY8/16 are considered YUV formats, and the color_range is
not set - so the API user will have to assume limitted range. (Unless
the API user adds a special-case for the PNG decoder.)
Just export the correct range - full range.
