      Modified TaskTracker and related classes so that per-job local data on the TaskTracker node has right access-control. Important changes:
       - All files/directories of the job on the TaskTracker are now user-owned by the job-owner and group-owner by a special TaskTracker's group.
       - The permissions of the file/directories are set to the most restrictive permissions possible.
       - Files/dirs shareable by all tasks of the job on this TT are set proper access control as soon as possible, i.e immediately after job-localization and those that are private to a single task are set access control after the corresponding task's localization.
       - Also fixes MAPREDUCE-131 which is related to a bug because of which tasks hang when the taskcontroller.cfg has multiple entries for mapred.local.dir
       - A new configuration entry hadoop.log.dir corresponding to the hadoop.log.dir in TT's configuration is now needed in task-controller.cfg so as to support restricted access control for userlogs of the tasks on the TaskTracker.
