Add an mbuf pointer parameter to (*ext_free) to give the external
free function access to the mbuf the external memory was attached
to.
Mechanically adjust all users to include the mbuf parameter.
This fixes a long standing annoyance for external free functions.
Before one had to sacrifice one of the argument pointers for this.
