Rename site_rcfile to site_file, custom_rcfile to custom_file.
Remove append_tree and data fields.
(MU_PARSE_CONFIG_GLOBAL,MU_CFG_PARSE_PROGRAM): Remove.
(MU_PARSE_CONFIG_VERBOSE): Rename to MU_CF_VERBOSE.
(MU_PARSE_CONFIG_DUMP): Rename to MU_CF_DUMP.
(MU_CFG_FMT_LOCUS): Rename to MU_CF_FMT_LOCUS.

(MU_CFG_FMT_PARAM_PATH): Rename to MU_CF_FMT_PARAM_PATH.

(MU_CFG_COMPATIBILITY,MU_CFG_DEPRECATED): Remove.
(mu_parse_config, mu_get_config): Remove deprecated functions.

* libmailutils/cli/cli.c (mu_general_help_text): New global.
(app_data): New struct.
(init_options): Construct configuration option group depending on
which configuration files are in use.
(mu_cli_ext): Don't use per-user configuration files for servers.
Pass pointer to app_data structure as po.po_data
(mu_cli): Set MU_CFHINT_PER_USER_FILE flag by default.

* mail/testsuite/lib/mail.exp: Rewrite invocation of the mu_init command.
* include/mailutils/cli.h (mu_cli_setup) <server>: New field.

* comsat/comsat.c (cli): Mark as server.
(main): Bugfix: pass pointer to server to mu_cli.
* imap4d/imap4d.c (cli): Mark as server.
* pop3d/pop3d.c: Likewise.

* comsat/tests/testsuite.at: Use the --no-site-config
option.
* imap4d/tests/testsuite.at: Likewise.

* libmailutils/cfg/driver.c: Update.
* libmailutils/cfg/format.c: Update.
