It does not make anymore sense to allow building with older Libgcrypt

Given that the default for the keyid format is none, the subkey
fingerprints are important to do anything with a subkey.  Thus we make
the old option the default and provide a new option to revert it.

We used to pass PK as well as information which could be taken

--

Having always the single byte in the packet data than to store and
retrieve it from an MPI is much easier.  Thus this patch changes the
original internal format.  With this chnages decryption of the slighly
modified test data works now. See the bug tracker for test data.
