Regression test improvements:

Move the stop for LFCNWRAPSTOP to the point at which writing at segment 0
is really about to commence, since this is what the test expects (and
incidentally what a snapshotting utility wants as well).

More correctly reconstruct the on-disk state at every checkpoint, rather
than relying on the entire state at the point of wrapping to be accurate
(that is only true the first time we wrap).  Add a "make abort" target to
make rerunning the test more convenient when it has failed and we're done
analyzing the failure.
Fix a fencepost error in the bitmap handling in extend_ifile(), and another
in lfs_freelist_prev().
Build GENERIC kernel as part of make release.
Install notes into ${RELEASEDIR}/${RELEASEMACHINEDIR}, not
${RELEASEDIR}/${MACHINE}.  The former is the blessed way as it's
defined as a "subdirectory used below ${RELEASEDIR} when building a
release" and defaults to MACHINE in bsd.own.mk.

Make sure that ${RELEASEDIR}/${RELEASEMACHINEDIR} exists before
installing notes in to it.  It only ever worked because ~all ports
build at least one kernel as part of make release, and so the release
directory was created when kernel sets are installed.

XXX: Why don't we create ${RELEASEDIR}/${RELEASEMACHINEDIR} from the
top-level makefile before running make release?
One __KERNEL_RCSID() should be enough for this file.
Add several entries for minor (but maybe user visible) changes
I committed recently.
