* mail-crypto.c: New code to spawn off GPG/PGP to do stuff. Currently only deals with decryption. From Nathan Thompson-Amato <ndt@jps.net>, with bunches of changes from me. * session.c (mail_request_dialog): Expose the password dialog to the rest of the app (for use by the GPG/PGP code). * mail-format.c (handle_text_plain): Handle special inline data types. (Currently uuencoding, BinHex, and PGP encryption.) This is not the best way to deal with it, but it works for now. (try_inline_pgp): Convert an inline PGP-encrypted message into a multipart/encrypted part. (try_inline_binhex): Convert an inline BinHex attachment into an application/mac-binhex40 part (which we currently don't deal with...) (try_uudecoding): Convert a uuencoded attachment to an application/octet-stream part. (handle_multipart_encrypted): Deal with RFC2015 MIME-encoded PGP encrypted messages. (From ndt.) * mail-display.c (mail_text_write, mail_error_write): New utility functions. * Makefile.am (evolution_mail_SOURCES): add mail-crypto.c svn path=/trunk/; revision=4466
