Initialize the block field of the MpegEncContext pointer passed as parameter after making sure that the data is not corrupted.
In order to implement something like direct rendering instead of decoding coefficients in s->blocks and then copying them, copy them directly into the data_blocks array provided by xvmc.

Complete frame/field rendering by passing any remaining blocks.
Normally ff_draw_horiz_band() is called for each slice, however, some leftover blocks, for example from error_resilience(), may remain. It should be safe to call the function a few times for the same field.
