lavc/ass_split: check for NULL pointer in ff_ass_split_override_codes().
...
This is consistent with the other ff_ass_split_* functions.
It also fixes a crash when trying to split a dialog with text=NULL
(which seems to happen when the text of the dialog is empty); basically,
this commit fixes crashes when trying to encode an empty text subtitle
dialog (see subrip and mov_text encoders).
Fixes Ticket2048.

ass subtitles: Fix valgrind warnings.
...
We're now running some of this code through valgrind for the first
time, and a few warnings showed up stemming from two problems.
1) The ASS code assumes the subtitle header is null terminated, but
it wasn't, and passing the size down doesn't look like fun, so I
added a terminator
2) The code wasn't freeing all of its state.

ass_split: accept files with only \n and no \r.

The +1 is there to skip the ','.
With \r\n, the +1 skips the \r but that is ok.
With only \n, the +1 skips it and all hell breaks loose.
