Adds fixed up /usr/src/share

Adds fixed up /usr/src/share

	This patch adds many manual pages to /usr/src/share, including
the new manual pages for bpf, pcfs and spkr.  And most of the other parts of
/usr/src/share from the etcdist.  A lot of cleanup work went into fixing
the etcdist stuff when it was moved.

	A revised set of /usr/src/share/mk files is included that fixes
things like support for c++ files in make depend, make cleandir now removes
.depend, tags and the obj link/dir.  Added missing bsd.own.mk.  Added COPY
option to all install commands so you can turn one nob and get either
install -c or install.

	Fixed the manual page for tp.4, it had a \(*e (epsilon) character
request that mandoc did not grock, so I replaced it with the word epsilon.

Rodney Grimes about Andy Valencia's fix:
	This is a patch based upon Andy Valencia's patch to
/usr/othersrc/share/man/makewhatis.sed.  It REALLY fixes man -k.

NOTE:	This patch upgraded at patchkit 0.2.3 to fix usr.share vs share and
add much more of /usr/src/share.  Still did not move dict, doc and misc as
they are rather large.

NOTE:	Some of these man pages are seriously out of date and need to
be rewritten.  Also there are no device manual pages for the i386
architecture.  There are many man pages for the vax, tahoe and hp300
that could be edited into man pages for the i386, such as autoconf(8).
I did not include any of the other architectures in this patch, only
the i386 files.
