ff_mpv_common_init sets s->context_initialized.
This fixes decoding of h261 in the cases where the demuxer
hasn't already set the frame size.

This avoids trying to do sliced encoding, even if a slice/packet
size is requested (via the -ps option or the rtp_payload_size
field), since the encoder currently doesn't support it (or at least
our decoder can't decode it, even if the h261_encode_gob_header
function is hooked up to be called from the slicing part in
mpegvideo_enc.c).

Should improve cache usage and reduces stack usage.
Also reduces number of copies in case many levels
have the same number of bits.

If allocation fails earlier on, and the next frame is processed,
the slice buffer could be left in a state where line and data_stack
have already been freed, or are otherwise null pointers.

Not merged, conditions which are impossible should be checked by assert*()

The input packets are always assumed to be padded and
the av_fast_ family of function takes a pointer to a pointer.
