Stop adding ${CWARNFLAGS} to CFLAGS. The standard makefile processing will
add them automatically, and there is no point in adding them twice.

Add another level of checking to 'chkprintcap', which is done by
"skimming thru" the printcap file looking for some common mistakes that
people make. These are the kinds of mistakes where the printcap file
probably looks correct to human eyes, but is wrong in some subtle way
which causes a problem in some queue definitions. The program treats
these as "warnings" not "errors".
Note that I'm flexible on the m.f.c. schedule, if people would rather
this waited until after 4.5-release.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for usr.sbin/ to 8.

Fix additional warnings. Remove -Werror, since some people have complained
about it.

PR: 7886
Submitted by: Stefan Eggers <seggers@semyam.dinoco.de> (partially)

Remove -Werror from CFLAGS on i386 because with -nostdinc gcc spits
warnings from unused static inline functions in headers if you happen
to set CFLAGS without -O.

Make -Werror i386 specific because -nostinc on alpha spits warnings
for unused static inline functions in header files.

Use `foo/bar.a' instead of `-Lfoo -lbar' for linking to static internal
libraries so that `ld -f' in can create correct dependencies for
yet-to-be-built libraries.

Get the default BINDIR correctly (by including ../Makefile.inc recursively.
Override the default it it is wrong.

Don't override defaults when the defaults are correct.

Fixed DPADD.

Mega lpd/lpd upgrade, part I:

- Get rid of a lot of the static variables which were shared by
many routines and programs in the suite.
- Create an abstract interface to the printcap database, so that
other retrieval and iteration mechanisms could be developed
(e.g., YP, Hesiod, or automatic retrieval from a trusted server).
- Give each capability a human-readable name in addition to the historic
two-character one.
- Otherwise generally clean up a lot of dark corners. Many still remain.
- When submitting jobs, use the official login name record (from getlogin())
if there is one, rather than reverse-mapping the uid.

More to come...
