Removed more secret key related code.

It builds fine and passes some of the tests but there are quite some
features which don't work yet.

/****************
* Note about the pkey/skey elements: We assume that the secret keys
* has the same elements as the public key at the begin of the array, so
* that npkey < nskey and it is possible to compare the secret and
* public keys by comparing the first npkey elements of pkey againts skey.
* We assume that secret keys have the same number of parameters as
* the public key and that the public parameters are the first items
* in the PKEY array. Thus NPKEY is always less than NSKEY and it is
* possible to compare the secret and public keys by comparing the
* first NPKEY elements of the PKEY array. Note that since GnuPG 2.1
* we don't use secret keys anymore directly because they are managed
* by gpg-agent. However for parsing OpenPGP key files we need a way
* to temporary store those secret keys. We do this by putting them
* into the public key structure and extending the PKEY field to NSKEY
* elements; the extra secret key information are stored in the
* SECKEY_INFO field.
