Removed Files:
	basesrc/etc: changelist

Log Message:
Major overhaul, with help from Andrew Brown <atatat@netbsd.org>.

Features:
- Add a bunch of stuff to /etc/mtree/special to enable removal of
  /etc/changelist:
	- files which we want to monitor for changes but don't want to
	  see the diffs of (master.passwd, ssh_host_key, ...) are
	  tagged with "nomail"
	- files which we don't want to monitor are tagged with "exclude"
	  (such as netgroup.db, kvm.db, ...)
	- monitor /etc/mtree/special.local, /root/.ssh/*
	- remove /etc/changelist, and a bunch of XXX comments
	- use mtree(8)'s -D, -I, and -E to generate lists of files to
	  actually do the changelist stuff on.
	- support /etc/mtree/special.local as an optional user-provided
	  version of /etc/mtree/special (effectively, an enhanced
	  /etc/changelist)
- Add code to monitor: /etc/ifconfig.* /etc/raid*.conf /etc/rc.conf.d/*
  including support for these files being added and removed at will.
- If /sbin/fdisk exists, backup the output of "fdisk $disk" for all
  the active disk drives as part of $check_disklabels
- Check permissions on: ~/.ssh/* ~/.shosts

Details:
- Reorder initialisation of defaults
- Remove special case for /etc/master.passwd "monitor but don't email diffs"
  with general case for other similar files.
- Keep all `autogenerated' files (such as disklabel.*, setuid.current, ...)
  in "$backup_dir/work", to minimise name clashes.
- Add migrate_file(old, new) to do the hard work of migrating files
  from the old `top level' /var/backups mechanism to the `full path'
  mechanism recently added. Use this appropriately.
- Add backup_and_diff(file, printdiffs), to the hard work of backing-up
  and diff-ing files.
- Cleanup use of shell redirects
- /bin/sh supports ~root globbing, so use it.
- Improve umask checking; use awk regex rather than awk math
