These aren't a part of or use libjail(3), but rather are direct
syscalls. Still, they seem like good additions, allowing us to attach
to already-running jails.
(cherry picked from commit a6499c56ab)
This is implemented as an iterator, reusing parts of the earlier logic
to populate jailparams from a passed in table.
The user may request any number of parameters to pull in while we're
searching, but we'll force jid and name to appear at a minimum.
(cherry picked from commit 6a7647eccd)
The name or jid always gets added to the params, and that's enough to
avoid allocating a 0 length params array.

(cherry picked from commit e175b519a6)
libjail is pretty small, so it makes for a good proof of concept demonstrating
how a system library can be wrapped to create a loadable Lua module for flua.
* Introduce 3lua section for man pages
* Add libjail module
