Generic types for FSNamesystem
------------------------------

                 Key: HADOOP-670
                 URL: http://issues.apache.org/jira/browse/HADOOP-670
             Project: Hadoop
          Issue Type: Improvement
    Affects Versions: 0.7.2
            Reporter: Konstantin Shvachko
         Assigned To: Konstantin Shvachko
             Fix For: 0.8.0
         Attachments: Generics.patch

I introduced generic types for FSNamesystem class.
I tried to keep interfaces in declarations of the member as general as possible
in order to have flexibility to change types of instances in the future.
I tried to contain changes within one java file.

I also replaced Vector types by ArrayList. Vectors are synchronized,
which we don't need since we already have top level synchronization in FSNamesystem.
