Log message:
Beginning of overhaul of middle layers:
Process list is now gathered first and knitted into a tree later.  This
saves generating fake entries for processes, as we know about all the
processes when we start knitting.
There's now a "virtual root process" pointed to by vroot, whose purpose is
to act as a parent for processes with no other parents.  This will allow
me to remove the remaining hardcoded references to PID 1 (except that
pstree with no arguments is defined to be equivalent to "pstree 1").
