ralloc: Delete autofree handling.

There was exactly one user of this, and I just removed it.

It also accessed an implicit global context, with no locking.  This
meant that it was only safe if all callers of ralloc_autofree_context()
held the same lock...which is a pretty terrible thing for a utility
library to impose.
