Andreas Rheinhardt	fe63b3eedc	avcodec/ffv1: Simplify cleanup after allocation failure Now that ff_ffv1_close() is called upon failure for both the FFV1 encoder and decoder, the code contained therein can be used to free the partially allocated slice contexts if allocating the slice contexts failed. One just has to set the correct number of slice contexts on error. This allows to remove the code for freeing partially allocated slice contexts in ff_ffv1_init_slice_contexts().

Andreas Rheinhardt	a0750f412a	avcodec/ffv1: Fix segfaults on allocation error When allocating FFV1 slice contexts fails, ff_ffv1_init_slice_contexts() frees everything that it has allocated, yet it does not reset the counter for the number of allocated slice contexts. This inconsistent state leads to segfaults lateron in ff_ffv1_close(), because said function presumes that the slice contexts have been allocated. Fix this by making sure that the number of slice contexts on error is consistent (namely zero). (This issue only affected the FFV1 decoder, because the encoder does not clean up after itself on init failure.)

Vittorio Giovara	4bb1070c15	ffv1: Explicitly name the coder type FFv1 uses two types of coders, golomb and range with two different tables. This is exposed this in a rather convoluted way, for example mentioning to set coder type 1 while initializing the variable 'ac' to 2, because encoder does not use range coder with default table. Appropriate internal coder type values have been added and used in any check rather than using raw numbers. Initialization of avctx.coder_type in ffv1dec is removed because this field is encoder only. An unneeded validation check in the encoder is dropped too.
