Commit 18590880 18590880814ffb1941ba9a67b49a246323e36d37 by Sergey Poznyakoff

Implement normal UNIX-style configuration files:

* mailbox/cfg_lexer.c: New file.
* mailbox/cfg_parser.c: New file.
* mailbox/cfg_parser.h: New file.
* mailbox/Makefile.am: Add cfg_ sources and socket_stream.c.

* include/mailutils/cfg.h: New file.
* include/mailutils/Makefile.am (pkginclude_HEADERS): Add cfg.h.
* include/mailutils/argp.h: Include cfg.h.
(mu_create_argcv): Remove prototype.
* include/mailutils/mu_auth.h (struct mu_auth_module): New member
`cfg'.
(MU_AUTH_REGISTER_ALL_MODULES): Call mu_auth_init first.

* mailbox/mu_argp.c: Rewrite. Implement normal configuration
(resource) file support. Overloaded command line options begin to
phase out.
* mailbox/mu_auth.c, auth/gsasl.c, auth/pam.c, auth/radius.c,
auth/sql.c, auth/tls.c, auth/virtual.c, libsieve/argp.c,
mailbox/system.c: Implement configuration statements.

* imap4d/imap4d.c: Begin switching to the new configuration scheme.
