[svn r37909] a much much much larger refactoring than i originally

intended at this point:

* HostManager and HostRSync are now acting
  more locally, also easier to test.

* HostInfo deals with setting up gateways now

* HostManager, HostRSync and HostInfo are
  all tested now in test_hostmanage.py
  (and do not involve a full startup of RSessions)

* for rsyncing, the original directory structure
  (relative to config.topdir) is preserved on the
  other side, this makes "dist_rsync_roots" relatively
  clean now (but it doesn't pick up things on the fly,
  only initialises at the beginning)

* added lots of tests

* removed more occurences of pkgdir

* streamlined and simplified some tests

* removed lots of tests that do not appear to test
  specifically enough (and caused trouble for
  the refactoring)

* removed lots of (but not all, i guess) test-specific
  functionality in hostmanage.py and a bit in rsession.py

* removed HostOptions() in favour of rather directly
  accessing config values
