Minor fixes.

* include/mailutils/debug.h (mu_debug_log_nl): New proto.
* libmailutils/diag/debug.c (mu_debug_log_nl): New function.
* libmailutils/mailer/progmailer.c: Use mu_debug_log_nl.
* libmailutils/server/acl.c: Likewise.
Also, use MU_DEBUG_TRACE9 instead of the numeric value.

* libmailutils/filter/iconvflt.c (_iconv_filter): Register encoder
(same as decoder).
