Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

(Hopefully) Last set of changes so all of lpr uses __FBSDID() for
setting rcsids, and uses a consistent format for 'sccsid' lines.

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.

Back out the previous change to the queue(3) interface.
It was not discussed and should probably not happen.

Requested by: msmith and others

Change the way that the queue(3) structures are declared; don't assume that
the type argument to *_HEAD and *_ENTRY is a struct.

Add missing argument to warn() call.

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...
