This commit adds a reference to the buffer as an argument to
start_frame, and adapts all existing code.
This allows for asynchronous hardware accelerators to skip
copying packet data by referencing it.
This commit is the AVHWAccel analogue of commit
20f9727018: 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.
