crypto/libcrypto: add driver for OpenSSL library
This code provides the initial implementation of the libcrypto poll mode driver. All cryptography operations are using Openssl library crypto API. Each algorithm uses EVP_ interface from openssl API - which is recommended by Openssl maintainers. This patch adds libcrypto poll mode driver support to librte_cryptodev library.

+LibCrypto Crypto Poll Mode Driver
+
+This code provides the initial implementation of the libcrypto poll mode
+driver. All cryptography operations are using Openssl library crypto API.
+Each algorithm uses EVP interface from openssl API - which is recommended
+by Openssl maintainers.
+
+For more details about openssl library please visit openssl webpage:
+https://www.openssl.org/
+
+Features
+--------
+
+LibCrypto PMD has support for:
+
+Supported cipher algorithms:
+* ``RTE_CRYPTO_CIPHER_3DES_CBC``
+* ``RTE_CRYPTO_CIPHER_AES_CBC``
+* ``RTE_CRYPTO_CIPHER_AES_CTR``
+* ``RTE_CRYPTO_CIPHER_3DES_CTR``
+* ``RTE_CRYPTO_CIPHER_AES_GCM``
+
+Supported authentication algorithms:
+* ``RTE_CRYPTO_AUTH_AES_GMAC``
+* ``RTE_CRYPTO_AUTH_MD5``
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_MD5_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA1_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA224_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA256_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA384_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA512_HMAC``
+
+
+Installation
+------------
+
+To compile libcrypto PMD, it has to be enabled in the config/common_base file
+and appropriate openssl packages have to be installed in the build environment.
+
+The newest openssl library version is supported:
+* 1.0.2h-fips 3 May 2016.
+Older versions that were also verified:
+* 1.0.1f 6 Jan 2014
+* 1.0.1 14 Mar 2012
+
+For Ubuntu 14.04 LTS these packages have to be installed in the build system:
+sudo apt-get install openssl
+sudo apt-get install libc6-dev-i386 (for i686-native-linuxapp-gcc target)
+
+This code was also verified on Fedora 24.
+This code was NOT yet verified on FreeBSD.
+
+Initialization
+--------------
+
+User can use app/test application to check how to use this pmd and to verify
+crypto processing.
+
+Test name is cryptodev_libcrypto_autotest.
+For performance test cryptodev_libcrypto_perftest can be used.
+
+To verify real traffic l2fwd-crypto example can be used with this command:
+
+.. code-block:: console
+
+sudo ./build/l2fwd-crypto -c 0x3 -n 4 --vdev "cryptodev_libcrypto_pmd"
+--vdev "cryptodev_libcrypto_pmd"-- -p 0x3 --chain CIPHER_HASH
+--cipher_op ENCRYPT --cipher_algo AES_CBC
+--cipher_key 00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:0f
+--iv 00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:ff
+--auth_op GENERATE --auth_algo SHA1_HMAC
+--auth_key 11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11
+:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11
+:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11
+
+Limitations
+-----------
+
+* Maximum number of sessions is 2048.
+* Chained mbufs are not supported.
+* Hash only is not supported for GCM and GMAC.
+* Cipher only is not supported for GCM and GMAC.
