Due to this bug in VC++ 2015 Update 1:
https://connect.microsoft.com/VisualStudio/feedback/details/2291638

the 'key' array in ff_read_riff_info() ends up being not null
terminated which led to failures in a Chromium unit tests. Update 2
should have a fix, but until then it is important to avoid problems.

This fixes retrieving a valid profile for many of the FATE conformance samples,
allowing them to be properly decoded by the HWAccel after adding a profile check.

The configure detection is bumped to X265_BUILD >= 68,
since API version 68 corresponds with the x265 1.8
release tarball. The warnings inside x265 about
12-bit being experimental were removed prior to API
version 72 a short time later.  At this time of
writing, X265_BUILD is at version 80.

12-bit support in the HEVC standard was approved in
October 2014 as part of HEVC Version 2 and published
in January 2015:

The index creation is O(N^2) with number of entries (typically thousands).
On a Pi this can take more than 60 seconds to execute for a recording of a few hours.

By replacing with an O(N) loop, this takes virtually zero time

Remove all files and functions which are not going to be reused,
and disable all functions and FATE tests temporarily which will be.

Since timecode_frame)start is a private option now, it stays at the default,
and is no longer written to the file.

Decodes YUV 4:2:2 10-bit and RGB 12-bit files.
Older files with more subbands, skips, Bayer, alpha not supported.
Alpha requires addition of GBRAP12 pixel format.

Fixes a theoretical issue if the resolution attribute is written
behind the aspect attribute.

The rightmost column is not decoded correctly.

Fixes a part of ticket #5195.
