Sets the MemVTable to use for memory allocation.
You can use this to provide custom memory allocation routines.
The vtable only needs to provide malloc, realloc, and free functions; GLib can
provide default implementations of the others. The malloc and realloc implementations should return
null on failure, GLib will handle error-checking for you. vtable is copied, so
need not persist after this function has been called.
Note that this function must be called before using any other GLib functions.
