Allow jail names (not just IDs) to be specified for: cpuset(1), ipfw(8), sockstat(1), ugidfw(8)

Most system utilities that work with jails allow the jail to be specified by name or ID, but a few are still ID-only. Use jail_getid(3) to fix the laggards.

Event Timeline

I had a memory of some utilities supporting any or -1 for "in a jail" (i.e. jid != 0). Might be worth looking at doing this too

I'm not a fan of this, though I understand its a copy

suggestion: rephrase prison to jail, and use whose (change prison in surrounding lines, too)

Yes, it's kind of ugly (same ugliness in libjail). But it's a limitation of struct iovec, which is geared toward bi-directional traffic even though the parameter names are always read-only. I didn't want to make a new data type, or to copy every name that gets passed to jail_get(2) or jail_set(2).

Sounds good - "prison" is now "jail". Except I went with "jail whose ID or name is" instead of "jail whose jail ID or name is"
