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

Have this use 'static const char rcsid' instead of __RCSID()

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.
