sweep of my licenses for consistency. (no functional changes) These
files have copyright held by people in addition to myself. (I did the
original work, they copied it, enhanced it, and added their copyright
to the derivative work.) Their approval has been given re: the license
change.

fix up NetBSD RCS Ids to match the standard, and the leading comment as
to match as well. No functional changes.

Updagte the VAX bits so they actually work. Use the common method of building
miniroots. Fix the ramdisk bits. Use the INSTALL kernel. This stuff has
really suffered from bitrot.

Sync with HEAD.
