a new java implementation of base64 for android-common

A new Base64 encoder/decoder class.  Some benchmarks comparing the
decoder it to those from android.os.Base64Utils (a decode-only native
implementation not accessible to apps) and
org.apache.commons.codec.binary.Base64, all with the JIT enabled:
