MFC r325717:

Remove __unused attributed on arguments that are actually used

MFC r290408:

Make rctl(8) use more reasonable buffer size for retrieving the rules.

MFC r290404:

Fix markup in rctl(8) - the 'rule' or 'filter' arguments are not optional.

MFC r287785:

Make it clear that 'swapuse' is swap reservation and not actual swap usage.

Remove spurious period.

MFC r282236:

Make rctl(8) more user-friendly when RACCT/RCTL is disabled for some reason.

Sponsored by: The FreeBSD Foundation

MFC r282213:

Add kern.racct.enable tunable and RACCT_DISABLED config option.
The point of this is to be able to add RACCT (with RACCT_DISABLED)
to GENERIC, to avoid having to rebuild the kernel to use rctl(8).

MFC r282901:

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.

Note those two are MFC-ed together, because the latter one changes the
name of RACCT_DISABLED option to RACCT_DEFAULT_TO_DISABLED. Should have
committed the renaming separately...

Add pcpu to the the rctl(8) manual page.

Remove references to userstat(1) and jailstat(1). Those tools were never
merged from the Perforce branch. They might be brought in when %CPU limits
go into the tree.

The .Fx macro needs the version number be in its own word separated by

Remove superfluous paragraph macro.

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.

Rename resource names to match these in login.conf.

Remove redundant assignments to WARNS.

For these directories, WARNS is already implied to be 6.

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.
