Implementation of AES-CTR CryptoCodec using JNI to OpenSSL

In HADOOP-10603, we have an implementation of AES-CTR CryptoCodec using Java JCE provider.
To get high performance, the configured JCE provider should utilize native code and AES-NI, but in JDK6,7 the Java embedded provider doesn't support it.

Considering not all hadoop user will use the provider like Diceros or able to get signed certificate from oracle to develop a custom provider, so this JIRA will have an implementation of AES-CTR CryptoCodec using JNI to OpenSSL directly.
