0451ff295a oggparsevorbis: use av_realloc consistently 
Memory passed to av_realloc cannot be allocated using memalign.

From 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:

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.
