Bugfixes.

* mailbox/mimehdr.c (_header_get_param): If buf is NULL
on entry, make sure it alwaus points to allocated memory
afterwards.

* examples/mimetest.c (charset): New variable.
(main): New command line option -c.
(message_display_parts): Use mu_message_aget_decoded_attachment_name.
Pass fname to mu_message_save_attachment.
