dict.c: Add dict_allocate_and_serialize
- this procedure atomically allocates a buffer and serializes dict into it.
- this procedure helps avoid memory corruptions due to race conditions where
in new members are added into dict between allocating a buffer for
serializing and actually serializing buffer into it.
