The sizes in the Algorithms chapter for aes_gcm was wrong or incomplete.

This directory contains all aes_ccm vectors.  However, effort is needed
to include them in the test suite so they are left for later.

The aes_ccm cipher is already covered by the vectors in crypt_SUITE_data

Will be increase interoperability of future SSL application versions.

The EVP_CIPHER_CTX interface aims at enabling using the same code for many
ciphers.  Since we are going to add aes_ccm which is similar to aes_gcm,
this commit is a preparation.

It creates the aead_(de|en)crypt nifs and removes the old ones.

MAY prevent compilation errors if the symbol is configured to not be defined in an OpenSSL version where it exists by default.

Trubble on a couple of cross-building machines

The final appearence of the rs_opts entry is still not completly decided.
