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.

mdoc: add missing .El

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.

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

mdoc: fix markup

Remove definitions for RACCT_FSIZE and RACCT_SBSIZE - these two are rather
performance-sensitive and not that useful, so I won't be merging them
before 9.0.

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.

Add manual page for rctl.conf(5).

Fix grammar and bump date.
