Garrett Wollman aaf08d94ca Make everything compile with -Wtraditional. Make it easier to distribute
a binary link-kit.  Make all non-optional options (pagers, procfs) standard,
and update LINT to reflect new symtab requirements.

NB: -Wtraditional will henceforth be forgotten.  This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax.  These were all
fixed, and the result of fixing some of them means that -Wall is now a
realistic possibility within a few weeks.
