Further optimize byte comparison methods
----------------------------------------

                 Key: HBASE-4012
                 URL: https://issues.apache.org/jira/browse/HBASE-4012
             Project: HBase
          Issue Type: Improvement
          Components: util
    Affects Versions: 0.92.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Minor
             Fix For: 0.92.0


Guava uses some clever tricks with sun.misc.Unsafe to compare byte arrays about 100% faster
than the naive byte-by-byte implementation: http://guava-libraries.googlecode.com/svn/trunk/guava/src/com/google/common/primitives/UnsignedBytes.java

We should borrow this [Apache 2 licensed] code.
