libavformat: fix incorrect handling of incomplete AVBPrint.
...
Change some internal APIs a bit to make it harder to make
such mistakes.
In particular, have the read chunk functions return an error
when the result is incomplete.
This might be less flexible, but since there has been no
use-case for that so far, avoiding coding mistakes seems better.
Add a function to queue a AVBPrint directly (ff_subtitles_queue_insert_bprint).
Also fixes a leak in lrcdec when ff_subtitles_queue_insert fails.

This commit also makes sure the extradata and subtitle_header are NUL

the size.
At the same time, it should fix 'warning: dereferencing type-punned

don't consider uint8_t** and char** compatibles.
