c0b34e6148 dvdec: drop unnecessary dv_tablegen.h #include 
dvdec.c uses nothing from dv_tablegen.h.  As a welcome side-effect, this
fixes compilation of that file with hardcoded tables enabled.

3c6607eb6f avcodec_encode_{audio,video}: only reallocate output packet when it has non-zero size. 
Otherwise realloc would free it, which would result in double free
later.

2ad405548b targa: convert to bytestream2. 
Also remove some write-only variables or write-only variable
assignments, remove internal colorspace conversion to native
endianness (that can be done by swscale much more efficiently),
and some cosmetics.

5484170ac7 rv34: set mb_num_left to 0 after finishing a frame 
Prevents running error resilience on a previous frame which will write
to the pic->mb_type[] array of the previous image. The array might
already be re-used for a new image in a subsequent thread, thus cause
two threads to write to the same pic->mb_type[] array, causing a race
condition which can crash in rv34_decode_cbp(), called by
rv34_decode_inter_mb_header() (which accesses mb_type[] twice,
assuming values are maintained, which the race condition breaks).
