MFC r314831:

Don't rely on dependency in Makefile.inc1 for strfile; make datfiles depend on strfile

In most cases strfile is built as part of build-tools, but in the event that someone
cd'ed to the directory, tried to build from scratch, and had MK_GAMES=no previously,
the build would fail in .../datfiles , trying to find strfile .

Mark this directory tree "SUBDIR_PARALLEL" safe to help facilitate this, instead of
shuffling around the SUBDIR entries (all of the other Makefiles will build standalone).

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Final step of eliminating the "games" distribution: Merge src/games
(or what's left of it, at least) into src/usr.bin.

This change will not be MFCed.

Add datfiles to SUBDIR for obj target too. "make install" wrote to the
source directory and failed when the source directory was nfs mounted.
This was fixed in 1.1.5. Sigh.

This commit was generated by cvs2svn to compensate for changes in r2490,
which included commits to RCS files with non-trunk default branches.

Bring in the 4.4 Lite games directory, modulo man page changes and segregation
of the x11 based games. I'm not going to tag the originals with bsd_44_lite
and do this in two stages since it's just not worth it for this collection,
and I've got directory renames to deal with that way. Bleah.
