04da20e58f dynarray: Change AV_ to FF_ for AV_DYNARRAY_ADD 
The header is not installed and the macro isn't used outside libavutil,
so it is obviously privat to libavutil. Make the name reflect that.

65b2feb890 avutil/mem: fix memleak 
The original code assumes av_realloc() will free ptr if size is zero.
The assumes is incorrect now.

d6ff68ad85 Factor duplicated ff_fast_malloc() out into mem_internal.h

6039248018 mem: fix pointer pointer aliasing violations 
This uses explicit memory copying to read and write pointer to pointers
of arbitrary object types. This works provided that the architecture
uses the same representation for all pointer types (the previous code
made that assumption already anyway).

d433e1aefa mem: Make av_strdup allocate using av_realloc 
This makes sure that pointers from av_strdup are reallocable,
which is used in av_dict_set if the AV_DICT_APPEND flag is set.

Nothing should rely on pointers from av_strdup being aligned.
