/* This little function is used by a couple of routers for expanding things. It
just saves repeating this code too many times. It does an expansion, and
chooses a suitable return code on error.
Arguments:
addr the address that's being routed
s the string to be expanded
prc pointer to where to put the return code on failure
Returns: the expanded string, or NULL (with prc set) on failure
