Ports related rc.d cleanups:

o Separate out local (ports) scripts that use rc.d, and the old style
  startup/shutdown scripts and execute them separately. On startup the
  rc.d style scripts are executed first and then the old-style scripts.
  On shutdown, exactly the reverse happens.
o The rc.d ports scripts should now behave more like base system scripts.
  Scripts ending in .sh will be sourced into the current shell, while the
  rest will be executed in a subshell. Previously, all ports scripts,
  regardless of the .sh suffix, were executed in a subshell.
o The parent script, /etc/rc.d/localpkg, passes its command line arguments
  straight to the rc.d ports scripts. This means they should now honor
  faststop and faststart commands as well. Old style scripts, should not see
  any differences. They will still get either a start or stop command.
o The initial phrase shown during shutdown has been changed to use
  "local packages" instead of "daemon processes" to be more inline with the
  phrase used during local package startup. The phrases are also used only for
  old-style ports script startup/shutdown, whereas previously they were being
  used for both rc.d and old-style scripts. This should make startup/shutdown
  output a bit less ugly.
