AV1 can put a frame into multiple reference slots;
up until now, this involved creating a new reference
to the underlying AVFrame; therefore av1_frame_ref()
could fail.
This commit changes this by using the ProgressFrame API
to share the underlying AVFrames.
(Hint: vaapi_av1_surface_id() checked whether the AV1Frames
contained in the AV1DecContext were NULL or not (of course
they were not); this has been changed to actually check for
whether said AV1Frame is blank or not.)

These defines are also used in other contexts than just AVCodecContext
ones, e.g. in libavformat. Furthermore, given that these defines are
public, the AV-prefix is the right one, so deprecate (and not just move)
the FF-macros.

This commit is the AVHWAccel analogue of commit
20f972701806be20a77f808db332d9489343bb78: It moves the private fields
of AVHWAccel to a new struct FFHWAccel extending AVHWAccel
in an internal header (namely hwaccel_internal.h).

libavcodec/hwconfig.h currently contains HWACCEL_CAP_* flags
as well as the definition of AVCodecHWConfigInternal and some
macros to create them.
The users of these two are nearly disjoint: The flags are used
by files providing AVHWAccels whereas AVCodecHWConfigInternal
is used by files providing codecs (for FFCodec.hw_configs).
This patch therefore moves these flags to a new file hwaccel_internal.h.

Support for VDPAU accelerated AV1 decoding was added with libvdpau-1.5.
Support for the same in ffmpeg is added with this patch. Profiles
related to VDPAU AV1 can be found in latest vdpau.h present in
libvdpau-1.5.
Add AV1 VDPAU to list of hwaccels and supported formats
Added file vdpau_av1.c and Modified configure to add VDPAU AV1 support.
Mapped AV1 profiles to VDPAU AV1 profiles. Populated the codec specific
params that need to be passed to VDPAU.
