First crack at real virtual domain support, i.e. mailing lists with the same

name in more than one domain.

- Totally eradicate MAILMAN_SITE_LIST, and in fact the entire need for a site
  list.  The functions that the site list previously performed are either
  removed or supported in other ways.  For example, instead of forwarding
  owner bounces to the site list, we now have a SITE_OWNER_ADDRESS which
  should point to a human, and such bounces are sent there instead.  There's
  also a "no reply" email address that should be set up to go to devnull.  For
  any message that never expects a reply, the sender is set to this address.

- Remove the Site.py module.  It was an experimental approach to trying to
  support virtual domains, and we're going to do it so much better now that
  this module is no longer necessary.  Site._makedirs() -> Utils.makedir().

- VIRTUAL_HOST_OVERVIEW is completely removed, since now virtual hosts are
  always enabled.  Virtual domains should be added to mailman.cfg by using the
  new add_domain() function.  add_virtualhost() is gone.  If no virtual
  domains are added explicitly, we add the default one that configure guessed
  (but we never add that if domains are added explicitly).

- Utils.get_domain() -> Utils.get_request_domain()

- withlist code cleanup and make sure that we load etc/mailman.cfg

- A new base exception called MailmanException is added, from which all
  exceptions defined in Errors.py ultimately derive.  MailmanError is retained
  and derives from MailmanException.

- BadDomainSpecificationError is added.

- Remove the -V/--virtual-host-overview option from list_lists and add instead
  -d/--domain and -f/--full.

- bin/update probably works but needs more testing.

- bin/newlist and bin/rmlist take fqdn list names, but default to the default
  domain if @whatever isn't given.  newlist's -u/--urlhost and -e/--emailhost
  options are removed.  The domain that the list is being added to must
  already exist.

- Minor code cleanup in Message.py

- Bump version to 2.2.0a1

- The Configuration object grows a .domain dictionary which maps email hosts
  to url hosts.  The reverse mapping is supported, but not directly; use
  Configuration.get_email_host() instead.

- Mailman/Cgi/create is converted from mm_cfg to config, and some minor code
  cleanup is performed.  Also, convert to __i18n_templates__ = True.

- New MailList APIs:
  + property .fqdn_listname
  + GetNoReplyEmail()
  + Create() API changes and refactoring.
