There is no longer any need for a list of them at runtime, because
decoders now carry the pointers to their associated hwaccels internally.
The file containing external declarations is now used to make the list
of hwaccels for configure.
This removes the dependency that hardware pixel formats previously had on
AVHWAccel instances, meaning only those which actually do something need
exist after this patch.
Also updates avcodec_default_get_format() to be able to choose hardware
formats if either a matching device has been supplied or no additional
external configuration is required, and avcodec_get_hw_frames_parameters()
to use the hardware config rather than searching the old hwaccel list.
ff_get_format() in the next patch will reject formats which aren't in the
offered list, so the hack in 7cb9296db8 is
no longer valid. Change the hack by adding a new field in the VP8 decoder
context to indicate that it's actually WebP and don't call ff_get_format()
at all in that case.
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.
Give a debug message when query attribute get VA_ATTRIB_NOT_SUPPORTED,
it's will help to trace and debug some issue.

This check is not needed for any supported version of libtls
