Thoughts? I *think* the flamewar over this change is finished but it might
be premature. But most of this probably should be done regardless IHMO.
Most of this de-emphasises "make world" in favor of the broken-down
"make buildworld; make buildkernel; etc" procedure we've been recommending
for a while now. There is one significant-ish procedural change, I moved
the "mergemaster -p" step to be first because there are cases that the
"make buildworld" step now checks to see if users/groups exist before it
will even begin compiling stuff...
