Fix MKRUMP = no build

Move rump kernel man pages from various sources to sys/rump

namely:
* src/lib is used only when building for POSIX'y platforms, but
the man pages have their use for all platforms
* rumpuser.3 is a function of the rump kernel, not one of the of
the POSIX'y implementation hosted in src/lib/librumpuser

no functional change

eliminate use of bsd.sys.mk from Makefiles

build and install intro(3lua) and intro(9lua)

Import the new apropos/whatis.

This code has been developed by Abhinav Upadhyay as part of Google's Summer
of Code 2011. It uses libmandoc to parse man pages and builds a Full
Text Index in a SQLite database. The combination of indexing the full
manual page, filtering out stop words and ranking individual matches
based on the section gives a much improved user experience.

The old makewhatis and friends are kept under MKMAKEMANDB=no for now.

Modify "makedb" so that WHATISDBDIR be used to specify the directory
to operate in (defaults to /usr/share/man)

use uname=${BINOWN} gname=${BINGRP} instead of uname=root gname=wheel

Move siginfo(5) and ucontext(5) to siginfo(2) and ucontext(2) resp.,
and fix references.
Per a discussion on source-changes around Sep 14 2003.

Add MKUNPRIVED; if not no has the same semantics as if UNPRIVED was defined.
Replace defined(UNPRIVED) tests with ${MKUNPRIVED} != "no"

Add MKUPDATE; if not no has the same semantics as if UPDATE was defined.
Replace defined(UPDATE) tests with ${MKUPDATE} != "no"

Improve documentation for these and other make flags.

Rename a large chunk of the make(1) variables which refer to a
program/tool from "FOO" to "TOOL_FOO". The new variables are:
TOOL_ASN1_COMPILE TOOL_CAP_MKDB TOOL_CAT TOOL_CKSUM TOOL_COMPILE_ET
TOOL_CONFIG TOOL_CRUNCHGEN TOOL_CTAGS TOOL_DB TOOL_EQN TOOL_FGEN
TOOL_GENCAT TOOL_GROFF TOOL_HEXDUMP TOOL_INDXBIB TOOL_INSTALLBOOT
TOOL_INSTALL_INFO TOOL_M4 TOOL_MAKEFS TOOL_MAKEINFO TOOL_MAKEWHATIS
TOOL_MDSETIMAGE TOOL_MENUC TOOL_MKCSMAPPER TOOL_MKESDB
TOOL_MKLOCALE TOOL_MKMAGIC TOOL_MKTEMP TOOL_MSGC TOOL_MTREE
TOOL_PAX TOOL_PIC TOOL_PREPMKBOOTIMAGE TOOL_PWD_MKDB TOOL_REFER
TOOL_ROFF_ASCII TOOL_ROFF_DVI TOOL_ROFF_HTML TOOL_ROFF_PS
TOOL_ROFF_RAW TOOL_RPCGEN TOOL_SOELIM TOOL_SUNLABEL TOOL_TBL
TOOL_UUDECODE TOOL_VGRIND TOOL_ZIC

For each, provide default in <bsd.sys.mk> of the form:
TOOL_FOO?= foo
and for the ${USETOOLS}=="yes" case in <bsd.own.mk>, provide override:
TOOL_FOO= ${TOOLDIR}/bin/${_TOOL_PREFIX}foo

Document all of these in bsd.README.

This cleans up a chunk of potential (and actual) namespace collision
within our build infrastructure, as well as improves consistency in
the share/mk documentation and provision of appropriate defaults for
each of these variables.

Rework METALOG manipulation:
- add '-D ${DESTDIR}' to INSTPRIV, so install(8) removes the leading
${DESTDIR} from the metalogged path
- provide ${METADB.add} variable (for "${CAT} -l >> ${METALOG}"), to make
it easier to replace manual metalog manipulation in the future.
- with manual metalog additions, don't add the leading ${DESTDIR} in the path
- in maketars, use "mtree -C ..." instead of
"mtree -D ... | sed -e 's,\(.*\) \(\..*\),\2 \1,";

Benefits:
- maketars "Parsing METALOG" step speeds up from 29 seconds to 1.2 seconds
on a P3-600.
(This also benefits "make installworld" at the top level.)
- ${DESTDIR}/METALOG is easier to read without the leading "${DESTDIR}"
on all the pathnames, and it's smaller as well.

Include <bsd.sys.mk> so CAT is defined in the UNPRIVED= USETOOLS=no case.

Use the new cat(1) locking functionality - should solve PR toolchain/16963.
If all goes well, will submit a batch of pull-up requests for netbsd-1-6
presently to bring these additions and fixes into 1.6.

if UNPRIVED, generate (synthetically) a metadata log for whatis.db

Use new "makewhatis" program to create whatis.db database.

branches: 1.19.4;
Run makewhatis.sh out of the source tree, rather than the makewhatis
out of DESTDIR. Besides eliminating a ordering, this is needed because
the new all-singing-all-dancing domestic/Makefile runs makewhatis for
you .. but it might not be in DESTDIR if only domestic is being installed.

convert from NOxxx= to MKxxx=no.
include <bsd.own.mk> if testing a MKxxx variable.

don't install in /usr/share if NOSHARE is defined

Don't try to get at ${DESTDIR} inside /usr/libexec/makewhatis; instead,
supply ${DESTDIR} as part of the command line argument in
src/share/man/Makefile, and use that modified $MANPATH to find
makewhatis.sed.

Add David Brownlee's new intro pages, with editing. (PR #534[23])
Also, while here, expand apparently incorrectly .Dd month abbreviations.
(I thought about doing this in tmac/doc-common...heh...that would have
allowed a possible reverse map back to abbreviations.)

Let "makewhatis.sh" handle "${DESTDIR}", fixes PR misc/5037.

merge lite-2.

rcsid fascism

Move makewhatis.sed into man0, and split the Makefile.

Use bsd.prog.mk, to deal with FILES.

- Makefile cleanups

Use ${INSTALL}.

Added man9 to SUBDIRs

do makedb in DESTDIR/...

convert to use makewhatis; eventually will need to use 'catman'

Add RCS indentifiers.

actually do subdirs; they aren't missing!
