svc - Initial commit, preliminary service manager

* This is a preliminary service manager frontend and demon.
  It is not yet ready for prime-time (lots of support bits
  are missing).

* The main premise of this program is to be able to create
  and manage services in a more robust fashion, obtain status,
  log recent output or all output, and so forth.

  Among the many features, this program uses the new REAPER support
  to ensure that all processes related to the service can be accounted
  for.

* Includes a comprehensive manual page that lists all target features
  (many of which are not yet implemented as of this commit).
