bce8e2f374 avcodec/on2avc: Use least max_depth for get_vlc2()

tables itself use 9 bits; therefore it is sufficient to read twice from
the table, yet this has been done thrice.

26cc9db744 avcodec/on2avc: Unify initializing quad and pair VLCs 
Up until now, quad VLCs are initialized with codes of type uint32_t,
pair VLCs with codes of type uint16_t. There were two separate loops in
the decoder's init function for each type of VLC. This commit unifies
this: The type of the codes are now passed in as void * and the actual
size of the codes is obtained from a table. This approach also allows to
use the smallest type for each VLC code table: some quad tables actually
fitted in uint16_t. This allows to remove about 7KB from the binary.

a01ca21bbb avcodec/vp3: Fix memleak upon init failure 
Up until now, there was no cleanup in case initializing the Theora VLC
tables failed, leading to memleaks. This commit gets rid of them by
setting the FF_CODEC_CAP_INIT_CLEANUP flag for all decoders in vp3.c;
this also allows to remove some (now redundant) cleanup code.
