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...
