avformat/imf: open resources only when first needed 
IMF CPLs can reference thousands of files, which can result in system limits
for the number of open files to be exceeded. The following patch opens and
closes files as needed.

0d34e21282 avformat/avisynth: fix frameprop version check 
Trying to be clever about determining between interface version 8
and 8.1 ended up with pre-8.1 versions of AviSynth+ segfaulting.

The amount of time between interface version 8.1 and 9 is small,
so just restrict the frameprop awareness to version 9 and call it
a day.

569a0d0012 avcodec/msmpeg4dec: Make initializing VLCs thread-safe 
This automatically makes the remaining mpegvideo-decoders
(namely msmpeg4v[1-3], mss2, VC-1, VC-1 Image, WMV-[1-3]
and WMV-3 Image) init-threadsafe.
These were the last native codecs that were not init-threadsafe;
only wrappers for external libraries and for hardware accelerations
are now not init-threadsafe.

656cb0450a avcodec/vp3: Add missing check for av_malloc 
Since the av_malloc() may fail and return NULL pointer,
it is needed that the 's->edge_emu_buffer' should be checked
whether the new allocation is success.
