I have just committed support for network interface cloning similar
to that in NetBSD.  Specific interfaces may be created with a command
of the form:

# ifconfig gif0 create

arbitrary interfaces may be created with a command like:

# ifconfig gif create
gif1

The name of the created device is printed to stdout in this case.

A list of currently loaded devices supporting cloning may be obtained
as follows:

# ifconfig -C
gif

This commit includes converting the gif(4) device to use cloning
to create device instances at runtime rather then specifying a
static number of them in the kernel config.  If you use gif and
configure them by a method other then gifconfig_gif# and ifconfig_gif#
entries in /etc/rc.conf you may have to change your configuration
to create each device before configuring it.  /etc/rc.network has
been updated to do this automatically.
