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).
