This reduces the risk for overflow in pathlogical cases.

If the input file contains other tracks (non video/audio) that
aren't included in ismindex, the global file duration as returned
by libavformat might not be equal to the maximum of the duration
of the actual included tracks.

The stream duration is used for calculating the duration of the
last fragment easily without manually parsing anything else than
the mfra/tfra atoms. When the global file duration was used
previously, the duration of the last fragment could end up wrong
if the streams weren't equally long.

os_support.h contains more precise workarounds for non-POSIX mkdir().

We do not support using filters without AVFilterGraph in practice
anyway, so there is no point in pretending we do.

The tool nowadays supports more than one track per file,
this makes reading the code slightly less confusing.

PATH_MAX is not necessarily available on all systems, e.g. it's
normally not available on MSVC, and is not guaranteed to defined

This takes care of null-terminating the buffer if it is too small,
which wasn't handled properly before.

Signed-off-by: Martin Storsjö <martin@martin.st>

Also change the snprintf size to use the full buffer, since
snprintf always null-terminates the buffer.

The Windows SDK in MSVC doesn't have mkdir, only _mkdir, and
MSDN says one should include direct.h to use it.

tools/graph2dot.c:85: warning: format ‘%lld’ expects type ‘long long int’, but argument 4 has type ‘int’

In Smooth Streaming, the fragments are addressed by time, and
the manifest only stores one list of time offests for all streams,
so all streams need to have identical fragment offsets. Warn if
this isn't the case, so that the user can fix the files instead of
getting failures at runtime when the fragments can't be found.
