DEVOPS-297. Make the current_hash file get updated every time you run configure if you are running it in a git repository.
TRQ-2369. Fix a problem with recovering what cpus are in use by running jobs at restart time for the pbs_mom.
Merge branch '4.2-dev' of https://github.com/adaptivecomputing/torque into 4.2-dev
Backport a fix supplied by WestGrid to 4.2. It had been only in master for some reason.
TRQ-2377. Make svr_evaljobstate() not change the job state for jobs in an exiting or a completed state. Also make job_wait_over() not alter states for jobs that are running, exited, or completed. This fixes a race condition scenario for jobs with future execution times.
don't have current_hash file in repo.
Added current_hash to files removed by distclean.
Fix a unit test issue when check forks.
TRQ-2347. Make a deep copy of the batch request instead of a shallow one to fix a segfault.

trq-2378 Check ptask for NULL before dereferencing it.
Fixed a problem where the stack size was not getting set
when allocating new threads resulting in very large amounts of
memory allocated for pbs_mom and pbs_server with the ulimit -s
size got large. (i.e. 300000). TRQ-2283
TRQ-2270. Remove the attempt to ping nodes that haven't reported a status update for too long. These nodes should simply be considered down as you can open connections to nodes that are down, even when using TCP. This technique is only reliable for nodes that are functioning but have no process listening on that port.
Fix a warning with the pinging removal check-in.
