Import lpd, a re-implementation of the lpr daemon following the latest
OpenBSD coding practices (fork+exec/privsep/pledge/...). It is only
intended to replace the lpd(8) daemon for the moment, not the lpr(1),
lprm(1), lpq(1) and lpc(8) commands.

This is a work in progress. The server part should be fairly functionnal,
but the printer part is not complete: remote printers should work, for
local printers it depends on the setup. Anyway, at this point it's better
in the tree than rotting on my disk.
