- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

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.

beforeinstall -> SCRIPTS.

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

$Id$ -> $FreeBSD$

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...

Change `install' to `${INSTALL}' so that default install flags can be
specified in the top level Makefiles.

Add missing ${.CURDIR}

Implementing the "lp" command.

This command is required to exist in terms of compatibility with the
Posix 1003.2 specification. It actually invokes the lpr service with
the proper options.
