    fix bug 2961, 'Partial retrieval not available with PGP/Inline encrypted messages'
    do a more thorough check before deciding to go ahead with a (ultimately
    failed) decryption attempt: check for the end of the encrypted block,
    don't just assume, (never assume, it makes an ...), that it must be
    there if the beginning of the block is found.
    Move some stuff, which is now used in both -mime and -inline,  into a
    new file, pgpcore/pgp_utils.[ch]
