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.

aef32ddf96 User and group identifiers the rctl(8) utility receives from the kernel 
are always in numeric form; don't try to resolve them by names.  This
speeds up rule listing with large rulesets by about 50%.

008d7c831f Add META_MODE support. 
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

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
