thorpej 65412a2710 Implement expansion of special "magic" strings in symlinks into 
system-specific values.  Submitted by Chris Demetriou in Nov 1995 (!)
in PR kern/1781, modified only slighly by me.

This is enabled on a per-mount basis with the MNT_MAGICLINKS mount
flag.  It can be enabled at mountroot() time by building the kernel
with the ROOTFS_MAGICLINKS option.

The following magic strings are supported by the implementation:

	@machine	value of MACHINE for the system
	@machine_arch	value of MACHINE_ARCH for the system
	@hostname	the system host name, as set with sethostname()
	@domainname	the system domain name, as set with setdomainname()
	@kernel_ident	the kernel config file name
	@osrelease	the releaes number of the OS
	@ostype		the name of the OS (always "NetBSD" for NetBSD)

Example usage:

	mkdir /arch/i386/bin
	mkdir /arch/sparc/bin
	ln -s /arch/@machine_arch/bin /bin
