Finished the bulk of changes for gnupg 1.9. This included switching to libgcrypt functions, using shared error codes from libgpg-error, replacing the old functions we used to have in ../util by those in ../jnlib and ../common, renaming the malloc functions and a couple of types. Note, that not all changes are listed below becuause they are too similar and done at far too many places. As of today the code builds using the current libgcrypt from CVS but it is very unlikely that it actually works.

Editorial changes and allow building with old libgcrypts. Changed order of some conditional to make to put the special case into the true branch. Indentation changes. Minor other changes to make the ECC code more similar to the rest of our code. It builds but many sefltests still fail. Need to fix that before using it with an ECDH enabled libgcrypt.
