snow3g: add driver for SNOW 3G library

Browse Source 
Added new SW PMD which makes use of the libsso SW library,
which provides wireless algorithms SNOW 3G UEA2 and UIA2
in software.

This PMD supports cipher-only, hash-only and chained operations
("cipher then hash" and "hash then cipher") of the following
algorithms:
- RTE_CRYPTO_SYM_CIPHER_SNOW3G_UEA2
- RTE_CRYPTO_SYM_AUTH_SNOW3G_UIA2

The SNOW 3G hash and cipher algorithms, which are enabled
by this crypto PMD are implemented by Intel's libsso software
library. For library download and build instructions,
see the documentation included (doc/guides/cryptodevs/snow3g.rst)

The patch also contains the related unit tests function to test the PMD
supported operations.

SNOW 3G Crypto Poll Mode Driver
===============================
The SNOW 3G PMD (**librte_pmd_snow3g**) provides poll mode crypto driver
support for utilizing Intel Libsso library, which implements F8 and F9 functions
for SNOW 3G UEA2 cipher and UIA2 hash algorithms.
Features
--------
SNOW 3G PMD has support for:
Cipher algorithm:
* RTE_CRYPTO_SYM_CIPHER_SNOW3G_UEA2
Authentication algorithm:
* RTE_CRYPTO_SYM_AUTH_SNOW3G_UIA2
Limitations
-----------
* Chained mbufs are not supported.
Installation
------------
To build DPDK with the SNOW3G_PMD the user is required to get
the export controlled libsso library, sending a request to
`DPDKUser_software_access@intel.com`, and compile it
on their user system before building DPDK:
.. code-block:: console
make -f Makefile_snow3g
The environmental variable LIBSSO_PATH must be exported with the path
where you extracted and built the libsso library and finally set
CONFIG_RTE_LIBRTE_PMD_SNOW3G=y in config/common_base.
