8fc9bd0d32 dict.c: Free non-strduped av_dict_set arguments on error.
Unfortunately this was not explicitly documented and thus
might be risky.
But all uses I could find in FFmpeg and one in VLC had a memleak
in these cases, and I could not find any that relied on the previous
behaviour.

1d81f7448c dict.c: use av_mallocz instead of av_realloc
Memory passed to av_realloc must come from malloc,
calloc or realloc, and not e.g. memalign. realloc(3):

The realloc() function changes the size of the memory block pointed to
by ptr to size bytes. (...) Unless ptr is NULL, it must have been
returned by an earlier call to malloc(), calloc() or realloc().

The issue has been found by debugallocation, a part of google-perftools:
http://code.google.com/p/gperftools/ .

This makes fate pass when using LD_PRELOAD-ed debugallocation.
