825d80e01c 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.

3cc1a9ed5a Rewrite the rctl(8) utility to make it possible to add multiple rules
in a single run.  This speeds up operation with large rulesets.

82bbee8b66 Build GENERIC with RACCT/RCTL support by default. Note that it still
needs to be enabled by adding "kern.racct.enable=1" to /boot/loader.conf.

b38a0800aa Rework rctl(8) manpage
- Note that kernel options are required
- Shift parameters around in SYNOPSIS to make it more clear that there are
  different modes
- For all literal symbols such as 'process' or 'loginclass' or 'wallclock',
  etc, make them into bold symbols with .Sy
- For each subject:subject-id:etc: use .Em to underline to make it more clear
  they relate to the rule syntax
- Document how devd(8) support works
- Move RSS warning to BUGS and replace RSS with 'memoryuse' since 'RSS' is not
  defined in the manpage
- Add more examples around listing existing rules
- Make rule syntax into a list to improve readability
- Add a list of subjects and their corresponding subject-id same as
  RESOURCES/ACTIONS have lists
- Note that rctl(8) takes affect on all current and future processes
- Note that amount can take human numbers
- Add reference to login.conf(5) in few places login class is mentioned

f1a6c7f032 mandoc complains loudly when <TAB>s are misused in columnated lists. Fix
this syntax violation and while I'm here also convert <TAB> to Ta and adjust
quotation marks in order to prevent this problem in the future.

752ffacc69 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.
