[PATCH 1/2] dmd: Use ~/.dmd.d/ by default when not run as root.

[Alex Sassmannshausen]

* modules/dmd/support.scm: Add copyright.
  (user-dmddir): New variable.
  (default-logfile): Use it instead of user-homedir.
  (default-persistency-state-file): Use it instead of user-homedir.
  (default-configfile): Use it instead of user-homedir, use init.scm
  as default name for configfile, ensure .dmd.d exists.
  (default-socket-dir): Add check for root, if #f, use user-dmddir as
  base for socket.
