History
Jamie Gritton 2b0d6f815e Remove a LOR, where the the sleepable allprison_lock was being obtained 
in prison_equal_ip4/6 while an inp mutex was held.  Locking allprison_lock
can be avoided by making a restriction on the IP addresses associated with
jails:

Don't allow the "ip4" and "ip6" parameters to be changed after a jail is
created.  Setting the "ip4.addr" and "ip6.addr" parameters is allowed,
but only if the jail was already created with either ip4/6=new or
ip4/6=disable.  With this restriction, the prison flags in question
(PR_IP4_USER and PR_IP6_USER) become read-only and can be checked
without locking.

This also allows the simplification of a messy code path that was needed
to handle an existing prison gaining an IP address list.
