Support the post-addhdr command.
(isparsed) Addresses are not parsed by DEFAULT lists.  This allows
  "$LIST" substitutions to be applicable to each list using the
   defaults individually.
(_defaults)  Removed.  _load_dfl is used to load
  all default values from configuration files.
(parse_address)  Retrieve the "whereami" value with get()
  instead of always using the installation settings.
(regen)  New routine.  Reconstruct the parsed configuration data from
  the raw configuration data, and save the result in the configuration file.
(deliver) Access address lists directly.
  Mj::SubscriberList and Mj::RegList, as well as a list of
  addresses can be used.  This routine is now used to deliver
  all mail that Majordomo sends.
(new)  Include the domain in the data stored by the List object.
  Adjust SubscriberList instantiation arguments
  to allow future backend enhancements.
(config_regen)  New routine.  Wrapper for Mj::Config::regen.
(update)  New routine.  Offer a generic way to replace the
  data for an existing subscriber database entry.
(mail_message, deliver, probe)  Call Mj::Deliver::deliver using a
  revised set of arguments.  This allows the Mj::Deliver and related
  modules to be detached from Mj::List, eventually to allow asynchronous delivery.
(post_start)  Add support for the addhdr command mode, which treats
  the here args as a (plain text) message body, and generates the
  necessary headers.
(_add_headers)  New routine.  Add From, To, Subject, Date,
  Message-Id, and Content-type headers.
Rename the "rewritefrom" field to "groups."  This is used by the
GLOBAL:owners sublist to track which owner maintains which mailing
lists.

(new)  Take a hash of arguments instead of just path and backend.
(add)  Probe using Bf::Sender::any_probe_sender, to allow other
messages than posts to be probed.
(setup_sendmail_domain)  Do not use the domain password on
the command line when regenerating aliases.  Instead, write
it into a temporary file and parse the commands in the file
with mj_shell.
(do_default_config)  Create DEFAULT:_install and GLOBAL:_install
  configuration files.  mj_cf_defs.pl and its derivates are  no longer
  used directly by Majordomo.
(install_config_templates)  Do not reveal the domain password
  on the command line during installation.
Copy fake installation default files into the temporary list
directories.
(install_config_templates)  Place all of the commands in one
temporary file.
Add notes on running "make clean" and recent default and delivery changes.
(generate_wrappers) Unlink the "dotted" version of each setuid script
before creating the link.  Running "make clean" is no longer necessary
to update the scripts during an upgrade.
(_announce)  Use a sequence number of "M0" to comply with the
recent changes to Mj::Deliver.
Version number is now 0.1200101270.
(any_probe_sender)  Trim any existing address extensions, and use
an equals sign between the type/seqnum and address abbreviation.
This makes any_probe_sender consistent with M_probe_sender.
(parse)  Parse addresses with digest volume and issue number,
which takes the form DVxxxNyyy.
(_setup)  Use a separate envelope sender for each destination object.
  This allows VERP probing for digest recipients, among other things.
(mail_message) Each delivery class now has a separate sequence number.

(deliver) Buckets for rationed bounce probes are now chosen randomly,
because the sequence number for each delivery class can be different.

(probe) The sequence number for each class must be set externally.
(do_digests)  Manufacture a sequence number from the volume
and issue number of each digest to allow VERP probing of digest
recipients.
