          Issue Type: Improvement
          Components: build

(This JIRA builds on HBASE-3691)

I'm working on simplifying how to use Hadoop Snappy from other based maven 
projects. The idea is that hadoop-snappy JAR and the SOs (snappy and 
hadoop-snappy) would be picked up from a Maven repository (like any other 
dependencies). SO files will be picked up based on the architecture where the 
build is running (32 or 64 bits).

For Hbase this would remove the need to manually copy snappy JAR and SOs 
(snappy and hadoop-snappy) into HADOOP_HOME/lib or HBASE_HOME/lib and 
hadoop-snappy would be handled as a regular maven dependency (with a trick for 
the SOs file).

The changes would affect only the pom.xml and the would be in a 'snappy' 
profile, thus requiring '-Dsnappy' option in Maven invocations to trigger the 
including of snappy JAR and SOs.

Because hadoop-snappy (JAR and SOs) are not currently avail in public Maven 
repos, until that happens, Hbase developer would have to checkout and 'mvn 
install' hadoop-snappy. Which is (IMO) simpler than what will have to be done 
in once HBASE-3691 is committed.
