Are there other callers that need custom free?

The libgit2 folks requested the ability to set memory allocation
routines, hence reftable_free().

Thanks.  Patrick or Han-Wen, can you say a little more about this use
case?  That would help with making sure we are making an API that
meets its needs.

For example, is a custom allocator something that would be set
globally or something attached to a handle?  If the former, would code
that uses xmalloc and free and gets #define-d away when used in
libgit2 work?  If the latter, what does the handle look like?

Thanks,
Jonathan
