- Significantly reduce overhead associated with bsd.port.mk by replacing .USE

  macro, which was invoking separate make(1) process for each of the main
  targets, with explicit make(1) targets and specifying the dependencies on
  those targets in normal Makefile way. This gives up to 4x speedup. For the
  ports relying on the old functionality (i.e. each main target in a separate
  make(1) process) provide a USE_SUBMAKE knob, which provides old behaviour;

- speed-up dependency registration process by the factor of two, which
  could be a great win especially for things like GNOME and KDE with very long
  dependency chains;

- clean-up internal structure of the file, so that it is easier to understand
  and extend it when necessary.
