0c9fc6e187 * replacing calls to not-always-available gmtime_r with our own code. 
The new helper function actually differs in semantics from gmtime_r,
     so if that seems to be a problem I can actually move it to dv.c
     completely, since only DV muxer uses the code anyway.

8f9298f801 * simplifying OpenDML AVI handling. 
* adding code to skip over JUNK. It turns out that video editing
     software uses junk to resize ix## chunks without actually
     scrubbing the data. That trips up our packet extraction
     code since it recognizes ix## entries as "packets". Basically
     we have to skip over JUNK chunks for exactly the same reason
     we have to skip over ix## entries.
