These functions are available in time.h (conditional on posix thread
safe functions) on mingw.
Previously, these functions weren't detected by configure, and
libavutil/time_internal.h provided replacements, even if time.h
actually contained definitions of them.
These mingw inline functions are currently defined as
"extern __inline __attribute__((__gnu_inline__))". In this case,
redefining a new static inline version of the same function with the
same name is tolerated.

- Improve block choices by counting 0-bytes in the entropy score
- Make histogram use uint16_t type, to allow byte counts from 16*16
(current block size) up to 255*255 (maximum allowed 8bpp block size)
- Make sure score table is big enough for a full block's worth of bytes
- Calculate *xored without using code in inner loop
This is the equivalent change for cuviddec after the previous change
for nvdec. I made similar changes to the copying routines to handle
pixel formats in a more generic way.
Note that unlike with nvdec, there is no confusion about the ability
of a codec to output 444 formats. This is because the cuvid parser is
used, meaning that 444 JPEG content is still indicated as using a 420
output format.
We need all the flags to be exposed to be able to pass them on to
HW decoders. I did not attempt to nuance any of the warnings about
flags being unsupported as there's no way, at the point we extract
flags, to say whether an HW decoder is being used.
Use av_ts2str() for AVFrame.pkt_dts/pts to avoid print the
pkt_dts/pts as negative number like:
"0, 3616613, -9223372036854775808, 1001, 3110400, 0x75e37a65"

SRT API Documentation:
This flag is superfluous if both parties are at least version 1.3.0
(this shall be enforced by setting this value to SRTO_MINVERSION if
you expect that it be true) and therefore support HSv5 handshake,
where the SRT extended handshake is done with the overall handshake
process.
This flag is however obligatory if at least one party may be using
SRT below version 1.3.0 and does not support HSv5.
This is in preparation for a patch for cbs_h2645. Now the packet's
rbsp_buffer can be owned by an AVBuffer.

Dav1dPictures contain more than one buffer reference, so we're forced to use the
API properly to free them all.

Use of this function can save unnecessary malloc operation
in bitstream filter.
