Add autocrypt header parsing to mutt_parse_rfc822_line().

Convert parse_parameters() for autocrypt header usage:

  * change to use a BUFFER to accomodate large autocrypt keydata
    attribute values.

  * Autocrypt header parameters are not rfc2231 compliant.  Rather
    than rolling another very similar function, just change the
    existing one to allow space separation.
