Free everything on exit
        The server should now exit with zero allocated strings and
        zero allocated blocks.

Test cases
        Added a few test cases for improved coverage and recently
        fixed bugs.

(initialize): Lock the database before opening it.
(main): Unlock the database.

	with TRACED_ALLOCATIONS.

        set-pers-flags

Modified RPC calls
        create-person (new parameter pers-flags)

Removed several hard-coded constants and paths.
        Max texts
        Max conferences
        Nologin file

Support for aux-item validation functions (not just regexps.)
Support for aux-items that can only be created by the server
Support for linking pairs of aux items

Added test cases to improve code coverage

Renamed log to kom_log to avoid conflicts with math function log.

Several bug fixes (code and documentation)

(server_init): Remved the "mux_port" argument.  Don't listen for muxes.
(initialize): Don't pass the "mux_port" argument to server_init.

(initialize): Pass param.ip_client_host to server_init.

of possible open files.

	configuration 1002.  Fill in fd_relocate with PROTECTED_FDS.

(sighandler_hup): Use 1 instead of TRUE as value of go_and_die.
(sighandler_usr1): Use 1 instead of TRUE as value of
	do_statistics.  Use do_statistics instead of do_sync_db.

	running under DejaGnu.

	Get the file of the aux_def_file from the config file.
(main): Removed the -c and -a options.  This reverts the change in rev
	0.64.  It is more consistent to get the file name of the
	aux-def file from the config file.  The -c option was buggy anyhow.

(init_data_base): Removed unused argument dir_base.  All callers updated.
(sighandler_hup): Flag unused argument.
(sighandler_quit): Likewise.
(sighandler_usr1): Likewise.
(sighandler_usr2): Likewise.
(go_daemon): Make it a function prototype.
(initialize): New static.

               Documented the aux-item definition file format.
               Updated the database format documentation.

Server:        Implemented aux-items.
               Checked error returns and set error-status to something
                   useful in most cases.
               New RPC calls:
                   create-text
                   create-anonymous-text
                   create-conf
                   create-person
                   get-text-stat
                   get-conf-stat
                   modify-text-info
                   modify-conf-info
                   get-info
                   modify-server-info
                   get-collate-table
                   set-expire
                   query-unread-texts
               New asynchronous messages:
                   new-text
                   deleted-text

(go_daemon): Likewise.
(main): Likewise.
(sighandler_hup): Don't reinstall the signal if sigaction is available.
(sighandler_usr1): Likewise.
(sighandler_usr2): Likewise.

(sighandler_usr2): Reinstall the SIGHUSR2 handler.

	calculate it from supplied parameters.  All callers updated.

(initialize): Fixed a printf statement.
(main): chdir to param.core_dir before the action starts.
(datafilename): Removed.  All users modified
	to use param.datafile_name instead.
(backupfilename): Removed.  All users modified to use
	param.backupfile_name instead.
(textfilename): Removed.  All users modified to use
	param.textfile_name instead.
(statisticfile, pidfile, memusefile): Removed.  All callers modified
	to use param.statistic_name, param.pid_name and
	param.memuse_name instead.

(initialize): Fixed typo.

	file descriptors, if the config file says to do so.
	Moved code to calculate number of open connections here from main().
(main): Some code moved to initialize().
