r1692: first commit :)

* add IA64 to the architecture table of printer-drivers

* add new "net"-subcommands:

  net rpc printer migrate {drivers|printers|forms|security|settings|all}
        [printer]
  net rpc share migrate {shares|files|all} [share]

  this is the first part of the migration suite. this will will (once
  feature-complete) allow to do 1:1 server-cloning in the best possible way by
  making heavy use of samba's rpc_client-functions. all migration-steps
  are implemented as rpc/smb-client-calls; net communicates via rpc/smb
  with two servers at the same time (a remote, source server and a
  destination server that currently defaults to the local smbd). this
  allows e. g. printer-driver migration including driverfiles, recursive
  mirroring of file-shares including file-acls, etc. almost any migration
  step can be called with a migrate-subcommand to provide more flexibility
  during a migration process (at the cost of quite some redundancy :) ).

  "net rpc printer migrate settings" is still in a bad condition (many
  open questions that hopefully can be adressed soon).

  "net rpc share migrate security" as an isolated call to just migrate
  share-ACLs will be added later.

  Before playing with it, make sure to use a test-server. Migration is a
  serious business and this tool-set can perfectly overwrite your
  existing file/print-shares.

* along with the migration functions had to make I the following
  changes:

        - implement setprinter level 3 client-side

        - implement net_add_share level 502 client-side

        - allow security descriptor to be set in setprinterdata level 2
          serverside
