Improve the performance for pipe(2) again.  Also include some
fixes for previous version of new pipes from Bruce Evans.  This
new version:

Supports more properly the semantics of select (BDE).
Supports "OLD_PIPE" correctly (kern_descrip.c, BDE).
Eliminates incorrect EPIPE returns (bash 'pipe broken' messages.)
Much faster yet, currently tuned relatively conservatively -- but now
	gives approx 50% more perf than the new pipes code did originally.
	(That was about 50% more perf than the original BSD pipe code.)

Known bugs outstanding:
	No support for async io (SIGIO).  Will be included soon.

Next to do:
	Merge support for FIFOs.
