MFC r202468:
 
 Add security.jail.ip4_saddrsel/ip6_nosaddrsel sysctls to control
 whether to use source address selection (default) or the primary
 jail address for unbound outgoing connections.

 This is intended to be used by people upgrading from single-IP
 jails to multi-IP jails but not having to change firewall rules,
 application ACLs, ... but to force their connections (unless
 otherwise changed) to the primry jail IP they had been used for
 years, as well as for people prefering to implement similar policies.

 Note that for IPv6, if configured incorrectly, this might lead to
 scope violations, which single-IPv6 jails could as well, as by the
 design of jails. [1]

 Note that in contrast to FreeBSD 8.x and newer, where we have
 per-jail options, the sysctls are global for all jails.
