More tweaks to bounce parsing.
Add new bounce parsing test suite, plus a few tests.
Remove help files for obsolete commands.
Describe the uses of delays and sublists.
Document "full" mode, which displays subscriber count, digests, and so on.
Suggest mj2-dev instead of majordomo-workers.
Synch with latest changes (config templates, variable substitution
widths, eliminated aux* commands, lists-full, report-fail, etc.)
Remove configset-append from the list.
Adjust list_config_get parameters to include sublist.
Separate "lock" (lock expiration) trigger code.
Note the existence of the delay trigger.
Use lists-full instead of lists-aux to obtain supplementary info.
Use format width substitution extension to pad the address
to 48 characters.
Make it clear that the address need not be included in the command.
Remove aux* commands and add new auxiliary_list and delay topics.
(connect)  Do not validate addresses for requests from the resend
  and owner interfaces.
(dispatch) Simplify processing requests with multiple victims.
(substitute_vars_string) Allow formatting widths.  For example,
  $OWNER:48  would pad the list owner address out to 48 characters.
(list_config_get, list_config_set, list_config_set_to_default)
  Support the storage of configuration templates on a per-list
  basis.  All variables in a configuration template are visible
  without the use of a password.
(list_config_set)  Support "append" mode, which combines arrays
  of configuration settings.
(list_set_config)  Change the configuration file ('MAIN' by default)
  which is used by a mailing list.  This allows configuration
  templates to be accessed without changing the call arguments.
(lists) Use "full" mode to display supplemental data such
  as digest names, subscriber count, and list addresses.
  Add "config" mode to list configuration templates.  The
  descriptions for templates are taken from the comments setting.
(report) Add "succeed," "stall," and "fail" modes to
  differentiate log entries according to the result.
List who_access as a GLOBAL setting, closed by default.
(list_access_check) Make the name of the interface available
to the access rules.
Document the interface and invalid_from settings.
(is_array) Differentiate arrays that require blank lines between
  blocks from those that do not.
(parse_table)  Treat lines beginning with (optional white
  space and) "#" as comments, and discard them during parsing.
(load)  Do not automatically create a configuration file for a template.
(report)  Display dates on a separate line to conserve space.
The date will appear on a line, followed by a line for
each log entry on that day.
(_fill_config, _make_config, valid_config, set_config)
New routines to find, load, and validate configuration templates.
