API for formatting message sets on output
* libmailutils/msgset/print.c (mu_msgset_formats): New global. (mu_stream_msgset_format): New function. * include/mailutils/msgset.h (mu_msgset_format): New struct. (mu_msgset_fmt_imap, mu_msgset_fmt_mh): New defines. (MU_MSGSET_IGNORE_TRANSERR): New flag (mu_msgset_copy, mu_msgset_translate): New protos. (mu_stream_msgset_format, mu_msgset_imap_print): New protos. (mu_msgset_print): Deprecate. * libmailutils/imapio/sendmsgset.c: Use mu_msgset_imap_print instead of mu_msgset_print. * mu/libexec/imap.c: Likewise. * libmailutils/msgset/Makefile.am: Add copy.c * libmailutils/msgset/add.c (mu_msgset_add_range): Translate if message set mode doesn't match the requested one. * libmailutils/msgset/sub.c (mu_msgset_sub_range): Likewise. * libmailutils/msgset/trans.c (_mu_msgset_translate_pair): Act according to the mode argument. (mu_msgset_translate): New function. * libmailutils/tests/msgset.c: New option -mh * mh/mh_sequence.c (write_sequence): Rewrite. * testsuite/msgset.c: Optionally translate uids to msgnums and vice-versa.
