link2xt 1cd53aafff Add support for "Mixed Up" MIME format
This is an PGP/MIME format produced by Microsoft Exchange and ProtonMail IMAP/SMTP Bridge,
described in detail in https://tools.ietf.org/id/draft-dkg-openpgp-pgpmime-message-mangling-00.html

This patch adds seamless support for "Mixed Up" Encryption, repairing
mangled Autocrypt messages without notifying the user.
