The driver being used is detected inside av_hwdevice_ctx_init() and
the quirks field then set from a table of known device. If this
behaviour is unwanted, the user can also set the quirks field
manually.
Also adds the Intel i965 driver quirk (it does not destroy parameter
buffers used in a call to vaRenderPicture()) and detects that driver
to set it.
P010 is the 10-bit variant of NV12 (planar luma, packed chroma), using two
bytes per component to store 10-bit data plus 6-bit zeroes in the LSBs.

This fixes part of Ticket5676
This fixes kodi, mpv, chromium and ffplay build against 3.0 and linked to 3.1
This is a similar ABI fix to 1eb43af1a0

Currently it's exported as AVFrame.pkt_pts, which is also the only use
for that field. The reason it is done like this is that lavc used to
export various codec-specific "timing" information in AVFrame.pts, which
is not done anymore.
Since it is confusing to the callers to have a separate field which is
used only for decoder timestamps and nothing else, deprecate pkt_pts and
use just AVFrame.pts everywhere.
The new function behaves the same as av_log_format_line, but also forwards
the return value from the underlying snprintf call. This will allow
callers to accurately determine the size requirements for the line buffer.

This was suggested by wm4 and stefano.
After this patch using align=1 the size used by various functions would not
contain padding, while the palette would be aligned at align>1
This patch makes it required to use align>=4 if the palette is to be accessed
as uint32
As a side-effect It fixes storing pal8 in nut with odd with&height

This allows disabling the alignment by using a compact buffer

This will extend the whitelist features to allow blacklisting individual protocols and to
explicitly force everything to be enabled.

Libav, for some reason, merged this as a public API function. This will
aid in future merges.
A define is left for backwards compat, just in case some person
used it, since it is in a public header.

Adding mastering display metadata struct to avutil. The mastering display metadata contains information
about the mastering display color volume (SMPTE 2086:2014).
This info comes from HEVC in the SEI_TYPE_MASTERING_DISPLAY_INFO and is soon to be included in MKV:
https://mailarchive.ietf.org/arch/search/?email_list=cellar&gbt=1&index=sZyfPTM-QY69P-0omfOIiTN622o
so it is similar to SEI FPA / stereo_mode in MKV and as such this patch follows how AVStereo3D is implemented.
I'll add support to HEVC in a follow-up (and MKV when spec is approved).

The vector mode was deprecated in ARMv7-A/VFPv3 and various cpu
implementations do not support it in hardware. Vector mode code will
depending the OS either be emulated in software or result in an illegal
instruction on cpus which does not support it. This was not really
problem in practice since NEON implementations of the same functions are
preferred. It will however become a problem for checkasm which tests
every cpu flag separately.
Since this is a cpu feature newer cpu do not support anymore the
behaviour of this flag differs from the other flags. It can be only
activated by runtime cpu feature selection.
Pretty standard macros, these should help libav*
users avoid repeating ver.si.on parsing code,
which aids in compatibility-checking tasks like
identifying FFmpeg from Libav (_MICRO >= 100 check).
Something many are doing since we are not
intercompatible anymore.

There was no reason AFAIK for making AV_CRC_24_IEEE 12. This simply
resulted in wasted space under --enable-hardcoded-tables:
dynamic: 1318672 libavutil/libavutil.so.55
old : 1330680 libavutil/libavutil.so.55
new : 1326488 libavutil/libavutil.so.55
Minor version number is bumped, with ifdefry due to API breakage.
