mrg d436dd6641 extend sysinst disk handling, some general clean ups, better /etc support
and some sparc64 fixes.  details:

- new scripting_{,v}fprintf() that also write to the script log (if open).
- support of creation of LFS filesystems
- standard installs now allow one to choose which file systems to create,
out of the list of /usr, /var, /home, MFS /tmp, and swap.  a / is always
created, but the rest all optional. [*]
- new disklabel method: use existing.  this requires one to fill in the
mount points (and having at least a "/" is enforced).
- preservation of existing filesystems (at install) is supported.
- rewrote most of make_fstab(): the entire thing is generated from the
bsdlabel now, rather than hard coding / to 'a' and swap to 'b'.  create
MFS /tmp if requested.
- if IPv6 support isn't present, don't display any ipv6 messages.
- better rc.conf support
- sparc & sparc64 default to "cylinders" now.
- choosing "standard" instead of "standard with X" de-selects the X pkgs
by default.
- sparc64: don't install bootblocks until we have a complete system, avoids
booting with no /dev/console.
- sparc64: bump STDNEEDMB, it is way low.


[*] i have added default values for DEFVARSIZE & DEFUSRSIZE (this is used
only if /usr and /home are selected) to each port, based on STDNEEDMB.  as
such, my guesses might be wrong so port maintainers should look at these.
