s3-param: Move the options needed for running smbd in the AD DC to loadparm

s3-param: Move the options needed for running smbd in the AD DC to loadparm

This avoids the whole fileserver.conf thing, and simply handles everything in C.

The main challenge is that if s3fs is enabled in a member server
configuration (unlikely) then these options will not be set, and it
overrides any other attempt to set these as globals.  (The previous
approach essentially just changed defaults, because the include =
of smb.conf was after the values were set in fileserver.conf).
