9cca7be11d Relax CCM tag check. 
In CCM mode don't require a tag before initialising decrypt: this allows
the tag length to be set without requiring the tag.

c826988109 Sanity check EVP_CTRL_AEAD_TLS_AAD 
The various implementations of EVP_CTRL_AEAD_TLS_AAD expect a buffer of at
least 13 bytes long. Add sanity checks to ensure that the length is at
least that. Also add a new constant (EVP_AEAD_TLS1_AAD_LEN) to evp.h to
represent this length. Thanks to Kevin Wojtysiak (Int3 Solutions) and
Paramjot Oberoi (Int3 Solutions) for reporting this issue.
