ae34b6ff96 Add four new RCTL resources - readbps, readiops, writebps and writeiops,
for limiting disk (actually filesystem) IO.

Note that in some cases these limits are not quite precise. It's ok,
as long as it's within some reasonable bounds.

Testing - and review of the code, in particular the VFS and VM parts - is
very welcome.

a7ad07bff3 Change the way rctl interfaces with jails by introducing prison_racct
structure, which acts as a proxy between them.  This makes jail rules
persistent, i.e. they can be added before jail gets created, and they
don't disappear when the jail gets destroyed.

ec125fbbc5 Add rctl. It's used by racct to take user-configurable actions based
on the set of rules it maintains and the current resource usage.  It also
privides userland API to manage that ruleset.
