Added support for AES128-CCM based record encryption. AES128-CCM is similar to AES128-GCM. Both of them have same salt/iv/mac size. The notable difference between the two is that while invoking AES128-CCM operation, the salt||nonce (which is passed as IV) has to be prefixed with a hardcoded value '2'. Further, CCM implementation in kernel requires IV passed in crypto_aead_request() to be full '16' bytes. Therefore, the record structure 'struct tls_rec' has been modified to reserve '16' bytes for IV. This works for both GCM and CCM based cipher.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
