r5407: - this patch makes samba's event loop code more generic and makes

  using other implementations possible. This will be mostly usefull
  for client apps which have there own event loop and want to
  use our client libs

- add a example plugin for liboop (see http://liboop.org)
  NOTE: this just compiles and is completly untested
        and is commited only as example
