Use a global ps_context

* proclist.c, proclist.h (proclist_create_node): Use a
  ps_context passed by the caller; errors are no longer possible, rename
  to proclist_make_node and change the signature accordingly.
* rootdir.c, rootdir.h (rootdir_create_node): Likewise.
* main.c (main): Create the ps_context here and pass it to
  root_make_node.  (root_make_node): Pass it to proclist_make_node and
  rootdir_make_node.
