  qsvdec: Pass field order information to libmfx
  
  The VC-1 decoder fails to initialise if this is not set.

  qsvdec: Pass the correct profile to libmfx
  
  This was correct for H.26[45], because libmfx uses the same values
  derived from profile_idc and the constraint_set flags, but it is
  wrong for other codecs.
  
  Also avoid passing FF_LEVEL_UNKNOWN (-99) as the level, as this is
  certainly invalid.

• decode : restructure the core decoding code

  decode: restructure the core decoding code
  
  Currently, the new decoding API is pretty much just a wrapper around the
  old deprecated one. This is problematic, since it interferes with making
  full use of the flexibility added by the new API. The old API should
  also be removed at some future point.
  
  Reorganize the code so that the new send_packet/receive_frame functions
  call the actual decoding directly and change the old deprecated
  avcodec_decode_* functions into wrappers around the new API.
  
  The new internal API for decoders is now changing as well. Before this
  commit, it mirrors the public API, so the decoders need to implement
  send_packet() and receive_frame() callbacks. This turns out to require
  awkward constructs in both the decoders and the generic code. After this
  commit, the decoders only implement the receive_frame() callback and
  call a new internal function, ff_decode_get_packet() to obtain input
  data, in the same manner to how the bitstream filters now work.
  
  avcodec will now always make a reference to the input packet, which means
  that non-refcounted input packets will be copied. Keeping the previous
  behaviour, where this copy could sometimes be avoided, would make the
  code significantly more complex and fragile for only dubious gains,
  since packets are typically small and everyone who cares about
  performance should use refcounted packets anyway.
