b83affdc94 mxfdec: Merge last_partition and footer_partition 
FooterPartition offset specified in RIP takes precedence over any value written
in PartitionPacks. This fixes the same issue f06f6da tries to fix without
introducing an extra variable.

37c3686155 mxfdec: Parse PreviousPartition in mxf_seek_to_previous_partition() 
Without this patch the demuxer can get stuck in a loop if PreviousPartition
points somewhere where there's no PartitionPack, or if klv_read_packet() syncs
back up to the current partition.

This should fix Ticket3278 properly and unbreak Ticket4040.

842ea36c74 mxf: Override faulty PreviousPartition entries 
Some files set the PreviousPartition field to point to its own offset.

If we are parsing forward the Previous partition is immediately known
and its value could be used, otherwise we can safely point to the
header.

8cafeb8bca mxfdec: Validate parameters to strftime 
The MSVCRT version of strftime calls the invalid parameter handler
if the struct values in struct tm are invalid. In case no invalid
parameter handler is set for the process, the process is aborted.

This fixes fate failures on MSVC builds since 570af382.

Based on a patch by Hendrik Leppkes.
