Fix sscanf calls that can't work at the end of a line unless it ends
with \r\n or \n: the markup line may/should/must not end with these
characters.

This is a temporary workaround until all filters have been
upgraded to filter_frame and the framework can forget completely
about start_frame/draw_slice/end_frame.

Wrong code was commited in 64f4fb75.

This breaks the sed in configure:find_things(). Fixes regression from
c73c87b4. Fixes Ticket2079.

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.

Some wav files report a data size that is bigger than the actual file size.
Fall back to estimation from bitrate in such cases.

Fixes ticket #2065.

It was left over from the initial conversion.

It will overflow if somebody keeps streaming for a time long enough.

start_time is in stream timebase units while end_time is
in AV_TIME_BASE ones.

Consider the corner case with a list size larger than the wrap
number.

recording_time is in AV_TIME_BASE units.

Avoid calling av_get_frame_filename twice, once to generate the
segment filename and once to generate the playlist.

The segment path is desumed from the playlist path, recording a
relative path in the playlist while serving the file could lead
to misleading results.

Thread safe version of the common basename and dirname.
