reading it failed, ${pexp} ended up as the empty string and the script
would send SIGTERM to init(1), which was really inconvenient.
Fix that by never allowing pexp to become empty.
My patch considerably simplified by and ok  ajacoutot@.

its _flags in rc.conf(8).
When the rc.d(8) system starts a daemon, it will record its pexp under
/var/run/rc.d/rcscriptname and use that to interact with it (errors in
creating /var/run/rc.d or missing pexp file are non fatal, the framework
will just fallback to what it currently does).
deraadt@ doesn't mind a long as it doesn't come in the way of people
manually managing their daemons.

/var/yp/binding does not exist, do _not_ try to start ypbind.
Make it possible to start ypbind the same way as the other daemons
(using ypbind_flags) while preserving the historical startup behavior.

debug mode.
This commit also adds a force mode for the script to allow one to force
operations even if daemon_flags is set to NO.
In this case the sane default values will be used for each script.
e.g.: "/etc/rc.d/foo -f start" will start sshd even if it's disabled

specifically, rewrite them to permit some markup in the column headers,
and use "Ta" instead of literal tabs; mandoc does not currently match groff
100%, but a mandoc fix may be some time off, and we've gone enough releases
with poorly formatting column lists.
in some cases i have rewritten the lists as -tag, where -column made
little sense.

.Bl -column header1 header2 ... <Bl flags>
mixing things up confuses mandoc, and adding flags in can screw up the list.
this hopefully just makes things a bit safer (and more consistent).
(one more bit of work left and all column lists should format how we want)

which is used by (amongst other things) initgroups(3) to set the supplemantary
