Replace ${SYSCTL_W} with ${SYSCTL} in rc.d scripts, as they are identical.
This is a further clean up after r202988.

SYSCTL_W is still initialized in rc.subr as some ports may still use it.

Remove $NetBSD$ CVS tags. We no longer attempt to synch our rc.d files
with theirs, so this information doesn't need to be in the live file.
Having it in our CVS history is enough.

Remove the requirement for the FreeBSD keyword as it no longer
makes any sense.

Simplify setting of securelevel.

Luke Mewburn has indicated that they (NetBSD) are not interested
in keeping the scripts under rc.d in sync with us. So, remove
NetBSD specific stuff (which made our scripts more complicated
than necessary).

The NetBSD ident string will be left intact, both for history and
also incase we wish to pull in future versions.

Luke Mewburn has indicated that they (NetBSD) are not interested
in keeping the scripts under rc.d in sync with us. So, begin removal
of NetBSD specific stuff (which made our scripts more complicated
than necessary), starting with the NetBSD KEYWORD.

Move securelevel further back in the boot order.

o Add support for running /etc/rc.early
o Re-run through /etc/sysctl.conf a second time just before we set
the securelevel.

Convert from `${CMD_OSTYPE}` to ${OSTYPE}. This saves a shell invocation on
OS-dependent case switches.

Merge in all the changes that Mike Makonnen has been maintaining for a
while. This is only the script pieces, the glue for the build comes next.

Import the NetBSD 1.5 RC system.

Note that `rc' and `rc.shutdown' could not be imported because we already
have files with those names.
