  Remove support for building for mingw32ce (Windows CE)
Merged-by: James Almer <jamrial@gmail.com>

synth_superframe can be called twice per call to decode_packet.
It is not fully clear if calling ff_get_buffer on the same frame twice
is supported, so unref the frame first to be save.

There is no reason to keep this intact when decoding failed, specially
as private_ref is supposed to always be NULL when a frame is returned to
the user.

With there being two hwaccels that use the CUDA pix_fmt now, just
relying on the pix_fmt to identify the selected hwaccel is not enough
anymore.

So this checks if the user explicitly selected a hwaccel, and only
accepts that one.

Partially fixes t/6699.
