rc.d/sendmail: remove a obsolete upgrade seatbelt

This check was in place to aid the transition from sendmail pre-8.10.
8.10 was released in 2000. It's not possible to upgrade directly from
such as system (Freebsd 3?) to FreeBSD 15 so we can drop this.

rc.d/sendmail: Fix error with some configurations

The sendmail startup script can run 4 daemons: sendmail, sendmail_submit,
sendmail_outbound, and sendmail_msp_queue. Of the first 3 at most one
can be enabled. There's a run_rc_command call for each and the ones for
sendmail and sendmail_msp_queue run unconditionally. For some rc
commands this triggers warnings or errors when sendmail_enable="NO" or
sendmail_msp_queue_enable="NO". Since d2e7bb630b83 these errors are
propagated and the whole script fails.

Fix this by first determining which daemons are enabled, setting ${name}
and ${rcvar} accordingly, and then always calling run_rc_command
conditionally.

Also replace ${name}.cf with sendmail.cf because ${name} isn't always
sendmail.

rc.d/sendmail: Return non-zero if the daemon fails to start or is not running

If you have a mail server that is running sendmail daemon
(sendmail_enable=YES) and sendmail queue runner (sendmail_msp_queue=YES)
and the sendmail daemon dies, /etc/rc.d/sendmail status does see the
daemon is not running but returns 0 as the exit code. This prevents
other programs (like puppet) from restarting sendmail to fix the issue.

Make sure that the exit code is propagated towards the end of the script
if any of the sendmail services fail.

This patch does not call exit directly but instead just sets the exit
status code by calling exit in a subshell. This way we do not exit the
current shell in case the service script is sourced (e.g., when
rc_fast_and_loose is active).

rc.d/sendmail: Fix stopping service during shutdown

The sendmail service script needs to be stopped during shutdown
to ensure a clean shutdown of active SMTP connections (and writing
any in memory queue files).

rcorder(8) requires the rcorder block to be an uninterrupted sequence of
REQUIRE, PROVIDE, BEFORE, and KEYWORD lines. Having a comment in between
REQUIRE and KEYWORD makes rcorder stop parsing the block when it reaches
the comment.

Fix that by moving the comment out from the rcorder block.

rc.d: add a service jails config to all base system services

This gives more permissions to services (e.g. network access to
services which require this) when they are started as an automatic
service jail.

The sshd patch is important for the sshd-related functionality as
described in the man-page in the service jails part.

The location of the added env vars is supposed to allow overriding them
in rc.conf, and to hard-disable the use of svcj for some parts where it
doesn't make sense or will not work.

Only a subset of all of the services are fully tested (I'm running this
since more than a year with various services started as service jails).
The untested parts should be most of the time ok, in some edge-cases
more permissions are needed inside the service jail.

Move the rc framework out of sbin/init into libexec/rc.

The reasons for this are forward looking to pkgbase:
* /sbin/init is a special binary; try not to replace it with
every package update because an rc script was touched.
(a follow-up commit will make init its own package)
* having rc in its own place will allow more easy replacement
of the rc framework with alternatives, such as openrc.
