gets called from rc.local or rc.shutdown
- notify the user if a given operation was successfull or not by appending
the (ok) or (failed) strings to the end of the daemon name
- hide stdout and stdin unless RC_DEBUG=1 is set, otherwise all the function
names will be printed out and all output sent to stdin or stdout
- since from now on rc.subr is taking care of printing out the daemon names
on startup, we don't need to do this from rc.{local,shutdown} anymore

rc_cmd start/stop actions. This way when rc.d(8) scripts override these
functions, we don't loose rc_{pre,post}.
Add a max 5 secs loop after rc_stop in the rc_cmd top action. This seems
to be a good default for returning to command line only after the daemon
has really stopped. This fixes "restart" for some daemons and allows to
properly stop some others at shutdown time.
Note that this is just a best-effort default, some daemons may need a
lot more time to shutdown but this case is usually handled in the
rc.d(8) script itself and we obviously do not want to hang the shutdown
process.
Call rc_cmd start/stop in restart and _not_ rc_start/rc_stop which can
get overriden in a script.

As schwarze@ also stated, this will prevent anyone from calling it
(which would be an error) and makes it clearer that rc.subr is not just
a functions container.
No functionnal change, unless you were calling rc_conf from an rc script
which would have been wrong anyway.

script; instead, rc.subr can call rc_conf itself right after reading in
rc.conf.
from schwarze@ (committing on his behalf)
ok robert@

local_rcconf would get overwritten by flags from the rc script itself.
Based on an original idea and diff from robert@, create an rc_conf
function that we add in the rc_script after the defaults daemon*
variables.
This way we can use defaults variables names in other part of the script
(when defining a specific pexp for instance).
While here, simplify setting up the default daemon variables so that we
don't need to do any substitution in rc_start.
rc scripts must include daemon variables before calling rc_conf. All
other locally modified variables (pexp, rc_reload, local additions...)
must come after.
