Modified Files:
	basesrc/sbin/ifconfig [netbsd-1-5]: ifconfig.8 ifconfig.c

Log Message:
- Add `tunnel' and `deletetunnel' commands, which issue the ioctls
  that gifconfig(8) would issue to configure tunnel endpoints.  This
  allows IP tunnel interfaces (`gif' right now, and `gre' later) to
  be configured with ifconfig(8), and via /etc/ifconfig.<interface>.
  Partially taken from similar changes in OpenBSD.
- Const poison the command functions a bit.  We really need to clean
  up the command function interface.

Rationale for pulling into netbsd-1-5 branch: While this looks like
a feature enhancement, it actually fixes a bug -- without this change
or a change in rc.d's network bring-up, it is not possible to configure
IP tunnels as a normal part of bringing up the network.
