libthread: make pthreadperthread the default


libthread: add threadmaybackground Programs that want to background themselves now need to define threadmaybackground returning 1. This avoids a confusing (to people and debuggers) extra parent process for all the threaded programs that will never want to background themselves.


tmac: rename IM (italic manual) to MR (manual reference) Suggested by G. Brandon Robinson.


tmac: introduce real manual reference macro instead of overloading IR The overloading of IR emits magic \X'...' sequences that turn into HTML manual links. But not all such IR invocations should be manual links; those had to be written to avoid the IR macro before. Worse, the \X'...' ending the IR causes troff to emit only a single space after a period. Defining a new IM macro for manual references fixes both problems. Fixes #441.


libthread: run first thread in proc on system stack For pthread systems that are fussy about which stack is used, this makes sure that threadmain runs on a system stack. If you only use proccreate (never threadcreate), all threads run on system stacks.
