Merged fix for TRQ-2139 from 4.2-dev branch: epilogue.parallel tries to write a .OU and .ER file which will not be used. File creation fails.
TRQ-2098. Fix a port issue.
Fixed a problem in blcr_checkpoint_job where the function would
not return a failure when it failed to get a connection. The
negative value returned from connect was being used like a valid
handle and when it made it to pbs_disconnect it caused a seg-fault.
The code now returns with an error. TRQ-2132
Changed version to 4.1.8
TRQ-1528: valgrind errors.
