Jordan K. Hubbard 40ae4689df Lots of fixes:
1. Revamp package installer to use new dependency lists and also
   pkg_add's new `read from stdin' mode to prevent a copy of the package
   from hitting the disk unnecessarily.

2. More fixes for running "not as init" - don't get upset if CDROM already
   mounted, do the right thing instead.

3. If running as init, assume first-time install and _don't show the
   (W)rite option in the fdisk screen.

4. Many other little tweaks, some of which will have to wait for fuller testing
   until I can create a boot floppy (testing certain system-destroying
   features of sysinstall can be a royal pain).  Expect some more commits.
