Jerome Borsboom 89651c82b8 avcodec/vc1: support multi-slice field interlaced pictures with hwaccel 
When using hardware accelerated decoding for multi-slice field interlaced pictures,
only the first slice was decoded. This patch adds the neccesary looping over the
remaining slices that may exist in field interlaced pictures. Additionally, we align
the calculation of mby_start for the second field with the method given in VC-1 spec.

Mark Thompson 758fbc54fe lavc: Add hardware config metadata for decoders supporting hardware output 
This includes a pointer to the associated hwaccel for decoders using
hwaccels - these will be used later to implement the hwaccel setup
without needing a global list.

Also added is a new file listing all hwaccels as external declarations -
this will be used later to generate the hwaccel list at configure time.

wm4 70143a3954 dxva: add support for new dxva2 and d3d11 hwaccel APIs 
This also adds support to avconv (which is trivial due to the new
hwaccel API being generic enough).

The new decoder setup code in dxva2.c is significantly based on work by
Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites.

Merges Libav commit f9e7a2f95a.
Also adds untested VP9 support.
The check for DXVA2 COBJs is removed. Just update your MinGW to
something newer than a 5 year old release.

Philip Langdale 91f1115a0e avcodec/vc1dec: Re-order init to avoid initting hwaccel too early 
At least for vdpau, the hwaccel init code tries to check the video
profile and ensure that there is a matching vdpau profile available.

If it can't find a match, it will fail to initialise.

In the case of wmv3/vc1, I observed initialisation to fail all the
time. It turns out that this is due to the hwaccel being initialised
very early in the codec init, before the profile has been extracted
and set.

Conceptually, it's a simple fix to reorder the init code, but it gets
messy really fast because ff_get_format(), which is what implicitly
trigger hwaccel init, is called multiple times through various shared
init calls from h263, etc. It's incredibly hard to prove to my own
satisfaction that it's safe to move the vc1 specific init code
ahead of this generic code, but all the vc1 fate tests pass, and I've
visually inspected a couple of samples and things seem correct.

Gwenole Beauchesne 9f8e57efe4 vaapi: define a unique pixel format for VA-API (AV_PIX_FMT_VAAPI). 
Deprecate older VA pixel formats (MOCO, IDCT) as it is now very unlikely
to ever be useful in the future. Only keep plain AV_PIX_FMT_VAAPI format
that is aliased to the older VLD variant.

This is an API change.
