This breaks API and ABI.

Should fix compile on systems missing yasm/nasm.

This should fix behavior introduced by commit
96573c0d. Av_rescale_rnd() is not
lossless so if two timestamps are equal after being rescaled they are
not always actually identical. This patch use av_compare_ts() to get
always a correct result.

Fixes issue 2679.

This patch completes the high bit depth h264 decoding support.

This patch lets e.g. dsputil_init chose dsp functions with respect to
the bit depth to decode. The naming scheme of bit depth dependent
functions is <base name>_<bit depth>[_<prefix>] (i.e. the old
clear_blocks_c is now named clear_blocks_8_c).

Note: Some of the functions for high bit depth is not dependent on the
bit depth, but only on the pixel size. This leaves some room for
optimizing binary size.

In high bit depth, the QP values may now be up to (51 + 6*(bit_depth-8)).

In high bit depth the pixels will not be stored in uint8_t like in the
normal case, but in uint16_t. The pixel size is thus 1 in normal bit
depth and 2 in high bit depth.

Earlier, AVIO_RDWR was handled as READ, and all the checks
for the AVIO_WRONLY flag explicitly meant the write-only case.
When changed from old AVIO/URL contants to AVIO_FLAG in
59d96941, these comparisons were updated incorrectly, by
mapping checks for AVIO_WRONLY to checks for AVIO_FLAG_WRITE.

When receiving RTP over UDP, the urlcontext is opened with
READ_WRITE flags.

This patch updates the flag comparisons to check for the same
conditions as the code did prior to 59d96941.
