r7391: - Added client-support for various lsa_query_trust_dom_info-calls and a

Browse Source 
rpcclient-tester for some info-levels.

  Jerry, I tried to adopt to prs_pointer() where possible and to not
  interfere with your work for usrmgr.

- Add "net rpc trustdom vampire"-tool.

  This allows to retrieve Interdomain Trust(ed)-Relationships from
  NT4-Servers including cleartext-passwords (still stored in the local
  secrets.tdb).

  The net-hook was done in cooperation with Lars Mueller
  <lmuelle@suse.de>.

  To vampire trusted domains simply call:

        net rpc trustdom vampire -S nt4dc -Uadmin%pass
