Add code to support GCM an CCM modes in evp_test. On encrypt this
will compare the expected ciphertext and tag. On decrypt it will
compare the expected plaintext: tag comparison is done internally.

Add a simple CCM test case and convert all tests from crypto/modes/gcm128.c

Thanks to Shay Gueron & Vlad Krasnov for report.

Simple example of CCM code use: translated from the FIPS self tests.

Make assembly language handling conditional on the "copy" platform

Add CMS_RecipientInfo_encrypt: this function encrypts an existing content
encryption key to match the key in the RecipientInfo structure: this is
useful if a new recpient is added to and existing enveloped data structure.

Add documentation.

Two example programs one for command line argument processing and
one for configuration file processing.

Fix some typos and update version number first added: it has now been
backported to OpenSSL 1.0.2.

Not sure why I am getting these now and not before.
