gpg: Remove options --pgp2 and --rfc1991.

Browse Source 
* g10/gpg.c (oRFC1991, oPGP2): Remove
(opts): Remove --pgp2 and --rfc1991.
* g10/options.h (CO_PGP2, CO_RFC1991): Remove.  Remove all users.
(RFC2440, PGP2): Remove.  Remove all code only enabled by these
conditions.
* tests/openpgp/clearsig.test: Remove --rfc1991 test.
--

The use of PGP 2.c is considered insecure for quite some time
now (e.g. due to the use of MD5).  Thus we remove all support for
_creating_ PGP 2 compatible messages.
