r3633: - moved module init functions to after smb.conf and command line

  parsing, so that module init can take account of lp_ parms (thats
  why gensec:krb5=no wasn't working)

- added a BASE-DISCONNECT torture test that tests server response to
  clients disconnecting with open lock and open requests pending
(This used to be commit 5205f598b8c0be6985e61cc842cc5da109ba5b7e)
