alfred 4285179bde Remove an 'optimization' I hope to never see again. 
The pipe code could not handle running out of kva, it would panic
if that happened.  Instead return ENFILE to the application which
is an acceptable error return from pipe(2).

There was some slightly tricky things that needed to be worked on,
namely that the pipe code can 'realloc' the size of the buffer if
it detects that the pipe could use a bit more room.  However if it
failed the reallocation it could not cope and would panic.  Fix
this by attempting to grow the pipe while holding onto our old
resources.  If all goes well free the old resources and use the
new ones, otherwise continue to use the smaller buffer already
allocated.

While I'm here add a few blank lines for style(9) and remove
'register'.
