Michael Niedermayer d6af6b0350 10000l fix and use more mmx2/3dnow code for mpeg4 qpel which has been written and commited long time ago but appearently never used, qpel motion compensation is 5% faster
now

Roman Shaposhnik 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.
