Revert "TRQ-2342: Merge fix from TRQ-2317/TRQ-1714: spool files left alone when MS is the same as pbs_server and there's an epilogue running."

This reverts commit c08cd62a56759d26740993947bf9d1c4129c555e.
TRQ-2342
Fixed all unit tests with cpuset enabled (--enable-cpuset)
TRQ-2351. moms that haven't been upgraded can't interpret the nppcu attribute for jobs. Make it so that this attribute is only set if you are running a cray enabled pbs_server.
Merge branch '4.2-dev' of https://github.com/adaptivecomputing/torque into 4.2-dev
TRQ-2319 - Use hwloc library calls instead of Torque ones
Fix for TRQ-2305: BLCR job not being cleaned up on MOM after qhold.
Merge from trunk fix for TRQ-2208: qhold hangs when the attribute on the pbs_server display_job_server_suffix = False.
Made it so two trqauthd daemons could not run at the same time.
TRQ-2118
TRQ-2319 - update configure.ac to require hwloc >=1.2 when building with
           --enable-cpuset.
updated CHANGELOG

Updated CHANGELOG

Conflicts:
	CHANGELOG
Updated exit(0) to exit(EXIT_SUCCESS) in req_rerunjob for continuity.
Made it so trquathd can be pinged. This was done so we
can make sure that only one trqauthd is running at a time.
TRQ-2118
Fix for TRQ-2199: Torque enforcing resources_min.nodes incorrectly.
Fixed a problem in issue_to_svr on a retry condition where
the batch reqeust gets freed before the associated task can
be freed.

Also modified reissue_to_svr to fix a segault where the batch_request
was null but we dereferenced it before checking.

TRQ-2368
TRQ-2118 - fix make failure when --enable-munge-auth set
Modified patch for TRQ-2118 to make it so TORQUE will compile
with --enable-munge-auth. Removed #ifndef MUNGE_AUTH conditionals
to simplify code.
Added alloc_br to scaffolding for issue_request unit tests.
TRQ-2373. Make it so that login nodes correctly restrict the number of jobs they can run to np=X.
