introduced when Local_to_global was introduced.
(copy_person): Likewise.
(copy_text_stat): Added a const qualifier.  Rewritten to decrease
	the probability that the same kind of bug is introduced here, that
	is, assign each field separately instead of assigning the entire
	struct at once.
(copy_aux_item_list): Now static.  Rewritten as above.
(coy_aux_item): Added const qualifier.  Rewritten as above.

(copy_text_stat): Likewise.
(copy_aux_item): Likewise.
(copy_aux_item_list): Removed (now static).

(sync-kom): Fixed bugs in the example.

specification of async-leave-conf.  More test cases.

Local_to_global was introduced.

(get-conf-stat-older): Document the mask argument.
(mark-text-old): Document that mark-type 0 is used to remove the mark.
(async-leave-conf): This message is always sent to a person when
 	that person ceases to be a member of a conference, whatever the
 	reason is.  The protocol specification used to say that it was
	only sent when a person was forced to leave a conference.  The
	current wording makes more sense, and it was also the implemented
	behavior, so update the specification rather than the program.

checking when copying file contents.  Allow compaction of the text
file even if there are errors in the data base.

(read_configuration): Handle backupfile_name_2.

(copy_file): Abort if we cannot seek or read the file we copy
	from.  Abort if the value we read didn't end in a newline, start
	with "T ", "C " or "P ", if the identity number in the data isn't
	what we expected, or if it isn't followed by a space.  This
	change attempts to detect file damage as early as possible.

and exporter of email to lyskom.

	invalid-password is returned.

(create-person-old): Document that the new person will be a member of
	his letterbox.
(create-person): Likewise.

implementation conform to the documentation.  More test cases.
Makefile improvements.  Remove some unused code.

	asynchronous messages, since the example is valid for lyskomd
	1.9 but not lyskomd 2.0.
(Asynchronous Messages): Encourage clients to use accept-async instead
	of trusting the defaults.  State that the obsolete calls may
	be non-existing.
