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.

e9acff8a01 lavu/fifo: fix a corner case in av_fifo_grow2() 
When the fifo is grown by exactly the current write offset, it would end
up with offset_w = nb_elems. If av_fifo_write_from_cb() is called in
such a state, the user callback would get callled with *nb_elems=0,
which will then cause the write to return without writing anything.
