Small changes in mount_critical_filesystems_zfs

avoid unnecessary eval, switch to $() and -ne.

from kre@, thanks!

Compare $_mount_es with 0

Add mount_critical_filesystems_zfs

The new function is similar to mount_critical_filesystems
but it walks through ZFS datasets and mounts matching entries.

Set the path unconditionally to what rc sets it to, so that when running
individual scripts like 'env - /etc/rc.d/syslogd restart' programs like
rcorder are found.

run_rc_command - don't prefix the rcvar variable name with the dollar sign.

The output without the dollar sign is less confusing as it's actual
valid shell syntax:

$ /etc/rc.d/foo rcvar
# food

The output without the dollar sign is less confusing as it's actual

food=YES

Brought up on tech-userlevel@ by Rocky Hotas with some LGTMs from
other people and no objections.

We still refer to '$food' in warnings/errors though.

Fix waiting for PIDs on stop.

Fix expansion of positional parameters. Also move the local
variable declaration to more apropriate place.

Prevent waiting for processes to exit forever by introducing _rc_kill_ntries,
which if set, will SIGKILL the processes that did not die yet.

Hide ps error about processes not found (we could be more specific...)
It is superfluous, since we print:
foo not running? (check /var/run/foo/foo.pid).

Use ps -A instead of ps -ax (-A means -ax, but -A is posix, -x is not)

Use ps -o args instead of ps -o command (same reason).

This makes no difference when the ps used is /bin/ps on NetBSD, but
can make a difference when some other ps command gets invoked instead.

Remove the expensive tests in _have_rc_postprocessor(), as proposed by apb@.
It more than halves the multiuser boot time on slow machines and brings
it back near to the previous level.

sleep for 0.05 seconds instead of 2 seconds when checking if the pids
are still alive for a much faster exit.

In rc.subr, add _have_rc_postprocessor function and use it instead of
inline tests like [ -n "${_rc_postprocessor_fd}" ]. The new function
performs a few new tests, including verifying that /etc/rc is still
running (using a new _rc_pid variable set by /etc/rc).

This is intended to deal with the case that a script run from /etc/rc
spawns a background process, then /etc/rc exits, but the background
process still has environment variables inherited from /etc/rc.

Fixes PR 46546.

'file system' for consistency with documentation (instead of 'filesystem').

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
"\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.
