Improve debugging in the category "auth".

* libmailutils/auth/mu_auth.c: Fix mu_debug calls. Use different levels.

Remove --debug-auth option.  Users should use --debug-level=auth instead.

* libmu_argp/auth.c: Remove.
* libmu_argp/Makefile.am (libmu_argp_a_SOURCES): Remove auth.c
* include/mailutils/libargp.h (mu_auth_cmdline): Remove.
* libmu_argp/cmdline.c (all_cmdline_capa): Remove mu_auth_cmdline.
