Refactor net_getparams() to make it easier to get params from sources other
than bootp and rarp.
The code which splits a serverip:/rootpath string into rootip and a plain
pathname is now a separate net_parse_rootpath() function that can be
called by others. The code that sets the kernel env vars needed for
nfs_diskless is moved into net_open() so that the variables get set no
matter where the params came from.
There was already code in net_open() that allowed for the possibility that
some other entity has set up the network-related global variables. It uses
the rootip variable as the key, assuming that if it is set all the other
required variables are set too. These changes don't alter the existing
behavior, they just make it easier to actually write some new code to get
the params from another source (such as the U-Boot environment).

This is the new unified bootstrap, sometimes known previously as the
'three-stage' bootstrap.
There are a number of caveats with the code in its current state:
- The i386 bootstrap only supports booting from a floppy.
- The kernel and kld do not yet know how to deal with the extended
information and module summary passed in.
- PnP-based autodetection and demand loading of modules is not implemented.
- i386 ELF kernel loading is not ready yet.
- The i386 bootstrap is loaded via an ugly blockmap.
On the alpha, both net- and disk-booting (SRM console machines only) is
supported. No blockmaps are used by this code.
Obtained from: Parts from the NetBSD/i386 standalone bootstrap.
