Windows: Network Provider registration at service start

Windows: Network Provider registration at service start

Windows 8, 8.1 and pre-releases of 10 have a horrible bug as part
of the upgrade process.  All non-Microsoft network provider services
are removed from the NetworkProvider "Order" registry value.  For
OpenAFS this has the side effect of breaking integrated logon and
all drive letter mappings to \\AFS.

During service start add code to:

 1. Add "AFSRedirector" before "LanmanWorkstation" if not present
 2. Add "TransarcAFSDaemon" to the end of the list if not present

If the service is running in SMB mode

 3. Remove "AFSRedirector" if present
