* Put newfs-and-mount code into a separate function, in case
we want to support non-ffs filesystems.
* Check for the currently-mounted root, and don't newfs or mount it.
Assumes md code will also avoid changing that partition.
* renames of files from one pathname within the target to another
(e.g., mv_within_target_or_die("/etc", "/etc.old");
* check to see if a partition name like "sd0a" is the current root
* Duplicate a file from the current root into the target root
(for copying /netbsd from RAMdisk into the target).
A no-op if the root is the install target).
Start using these where appropriate.
Change net.c to avoid losing any information when updating network
config files: where possible, do appends to files that might have more
info than we got from the user (e.g., /etc/hosts.)
Where possible, add comment saying file was created/modified by sysinst.
destination register bit pattern with 1.0), which automatically provides
corner case handling.
Missing ftwotox emulation originally reported by Norman Mackenzie in PR 4237,
but he proposed a different implementation.
- Map in all physical memory first in system space. This reduces
pmap_copy_page() and pmap_zero_page to 3 resp. 2 instructions.
- Have fized position user page tables. Makes the pv_table smaller
and all reverse references faster (and simpler).
- Remove the wiring code. Nobody doesn't even know what a DR32 is anymore.
- Simulate page reference bit by setting page invalid, as suggested by
Rich Draves in a paper for 1991 Mach Usenix Symposium.
This reduced the time spent in the pmap module to between 70-75% of
the previous; and made process startup _much_ faster.

Add target.c to Makefiles.
* Minor fixes:
* Fix buglet in disks.c: make sure the target /etc exists before
touching the target's /etc/fstab. (Could be even cleaner.)
* If the target root is on /, don't copy our temporary /etc/resolv.conf
to the target /etc/resolv.conf. (Could be even cleaner.)
* Don't write the DNS hostname into /etc/defaultdomain.
DNS search paths are often not the same as YP group names.
