bug 403

For a system with hyperthreads and GRES bound to specific CPUs,
there was an error in assigning CPUs

Previous logic would allocate job resources on such a node
rather than reject the job allocation on that node.

Previous logic would pick CPUs then
reject jobs that can not match GRES to the allocated CPUs. New logic first
filters out CPUs that can not use the GRES, next picks CPUs for the job,
and finally picks the GRES that best match those CPUs.

No change in logic, just rename a variable for greater clarity

Eliminate extra variable and avoid changing the contents of a string
Minor refactoring of commit fa0af103

None of these have ever occurred, but these changes will harden Slurm

Report anything that is world writable.

Directories created for executables, libraries, etc. have permissions
based upon the umask, which may not be desired.

/* Current code (<= 2.1) has it so we start the new
 * job with the next step id.  This could be used
 * when restarting to figure out which step the
 * previous run of this job stopped on. */

due to multiple free calls caused by job arrays submitted to
multiple partitions. The root cause is the job priority array
of the original job being re-used by the subsequent job array
entries. A similar problem that could be induced by the user
specifying a job accounting frequency when submitting a job
array is also fixed.

sacctmgr.

Some uninitialized variables, possible NULL pointers, etc.
None of these have been seen in practice that we know of, but
these changes will bulletproof the code

Never observed, but "clang" tool reports these as possible failures

If reservation create request included a CoreCnt value and more
nodes are required than configured, the logic in select/cons_res
could go off the end of the core_cnt array. This patch adds a
check for a zero value in the core_cnt array, which terminates
the user-specified array.
