Finit v4.0-rc3

This is a pre-release, for internal testing at Westermo at the moment. Version 4.0 replaces the previously planned 3.2 because of major changes, for instance; removal of the built-in inetd, incompatible changes to kernel command options and configure script. See the changelog for more detailed information. A fully up-to-date list of changes is expected for the GA release.
