Integrating http://code.google.com/p/gnupg-ecc/source/detail?r=15 .

The following works:
   gpg2 --gen-key (ECC)
   gpg2 --list-keys
   gpg2 --list-packets ~/.gnupg/pubring.gpg
   gpg2 --list-packets <private key from http://sites.google.com/site/brainhub/pgpecckeys>

ECDH doesn't work yet as the code must be re-written to adjust for gpg-agent refactoring.
