mh,maildir: speed up scanning.
* include/mailutils/sys/amd.h (_amd_message_append, amd_sort): New protos.
* libmailutils/base/amd.c (amd_array_expand): Call memmove only if there is
actually something to move.
(_amd_message_append, amd_sort): New functions.
* libproto/maildir/mbox.c (maildir_scan_dir): Append new messages to the
end of the array, and sort it afterwards. This avoids unnecessary memory
moves, which improves performance considerably, especially on large
mailboxes.
* libproto/mh/mbox.c (mh_scan0): Likewise.
