rc.subr(8): Fix markup -- use .It to set off a new item.

Bump date for previous and remove trailing whitespace.

Add shell implementations of basename and dirname to rc.subr. They
are supposed to mimic basename(1) and dirname(1), except that they
are usable before /usr/bin is mounted.

Allow "echo -n" to work as expected in rc.d scripts that are executed
by /etc/rc. Similarly for printf with a format that does not end with

Allow "echo -n" to work as expected in rc.d scripts that are executed
by /etc/rc. Similarly for printf with a format that does not end with
"\n". Previously, the partial line would not be visible on the console
until a newline was printed, possibly after an annoying delay.

This is done by adding echo() and printf() shell functions to rc.subr,
so that naive use of the echo and printf commands in rc.d scripts will
call these functions instead of the underlying commands. These shell
functions send a new "nop" metadata message after the partial line, and
the rc_postprocess function in /etc/rc disentangles the partial line of
plain output from the metadata "nop".

Also add a "-n" option to the print_rc_normal function in rc.subr,
and make some cosmetic changes.

Add a postprocessor to /etc/rc, which logs messages to /var/run/rc.log,
and which can suppress output in silent mode. Silent mode is enabled
via the new rc_silent variable, which defaults to a value that depends
on the kern.boothowto sysctl.

Part of the /etc/rc silent changes requested in PR 41946
and proposed in tech-userlevel.

Introduce and use the rcvar_manpage variable, which contains the manual page
name where the user should look at for documentation about rcvar. It defaults
to 'rc.subr(5)', as rc.subr is mainly used by rc.d scripts.

This variable is useful to let the daily, weekly, monthly and security scripts
tune the warning message shown when any of the variables they handle is not
properly set.

Closes PR misc/23908.

Implement ``one'' prefix to allow a "one shot" operation as if
${rcvar}=yes yet all the other prerequisite tests are still performed.
The existing ``force'' prefix is a sledgehammer that ignores all the
prerequisite checks and always returns a zero exit status; this is a
more gentle approach to the problem of "manipulate this disabled
service without editing rc.conf(5)".
