TRQ-2035. Do not retry contacting the server if validate_active_server() gives you the same name as the server you just attempted to contact.
TRQ-2065. Fix a problem with recovering running jobs after a restart. The job_usage_info struct on the node wasn't being populated correctly, leading to errors in pbsnodes and errors in freeing the jobs.
Added code to return walltime remaining attribute for calls
to req_stat_svr and req_selectjobs. This makes it so all
applicable qstat options return the correct elapsed time
for display. TRQ-1133
Reverted the fix for commit d75c7a93e0212fe8c97cc02db96533d7c5b71c4b
which was a fix for TRQ-1976 where we were trying to alleviate
problems with the server hanging because of live locks. The real
problem for the TRQ-1976 issue is a need to be able to throttle
incoming connections to pbs_server so the change is not needed and
led to a regression reported in TRQ-2063. This change fixes TRQ-2063.
Modified cnt2server to make sure it still works correctly with
the qsub -b option. This was broken with the original fix for
TRQ-1478.
