avcodec/snow: Split ff_snow_get_buffer()

The part of said function that is common to both encoder and decoder
is negligible since c954cf1e1b766a0d1992d5be0a8be0055a8e1a6a
and more than offset by the costs of "Am I an encoder?" checks.

So move allocating the frames to the encoder and decoder directly.
Also rename ff_snow_frame_start() to ff_snow_frames_prepare(),
because a frame without a buffer has not been properly started.
