r2792: got rid of talloc_ldb_alloc() and instead created talloc_realloc_fn(),

so talloc now doesn't contain any ldb specific functions.

allow NULL to be passed to a couple more talloc() functions

+This is a non-macro version of talloc_realloc(), which is useful

+implementation encapsulates the functionality of malloc(), free() and
+realloc() in one call, which is why it is useful to be able to pass
+around a single function pointer.
