a6499c56ab jail(3lua): add jail.attach()/jail.remove() methods
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.

6a7647eccd jail(3lua): add a jail.list() method
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.

e175b519a6 lib/flua/libjail: Allow empty params table
The name or jid always gets added to the params, and that's enough to
avoid allocating a 0 length params array.

73577bf01d flua: Add a libjail module
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
