Internal pointers in CCM, GCM and XTS contexts should either be
NULL or set to point to the appropriate key schedule. This needs
to be adjusted when copying contexts.

We can't unfortunately print the CMAC cipher used without extending the API.

PR#2579
(cherry picked from commit 79e31a2842e10271581cbfdaae0145dd4bd35107)

Add patch originally accidentally omitted to allow CMAC to work with
EVP_PKEY APIs.

IN parameter.

Under the old docs, the only thing stated was "at most
EVP_PKEY_size(pkey) bytes will be written". It was kind of misleading
since it appears EVP_PKEY_size(pkey) WILL be written regardless of the
signature's buffer size.
