plan9: initial support for plan 9 from bell labs
This patch contains support for Plan 9 from Bell Labs. A README is
provided in contrib/plan9 which describes the port in greater detail.
A new extension is also provided named factotum which permits the
factotum(4) authentication agent to provide credentials for HTTP
repositories. This extension is also applicable to other POSIX
platforms which make use of Plan 9 from User Space (aka plan9ports).
