The container owner should have been SlurmdUser rather than job
owner for Prolog, Epilog and UnkillableProgram parameters

Make sure the UnkillableStepProgram runs in a job container owned
by the job's owner.

If a job preemption involves multiple preemption types (cancel +
requeue + suspend) and more than one job is preempted with one
of the preemption types being suspend and the other something else,
the preemptee initiation may be delayed longer than needed.

such that  1) specifying --without-rrdtool or --with-rrdtool=no works as
expected, disabling rrdtool build and  2) the link test also tests for
rrd_info_t which was not present in the old rrdtool-devel-1.2.27 which I
happen to have installed. It is present in the newer rrdtool I used from
rpmforge for centos5 rrdtool-devel-1.4.7-1.el5.rf.x86_64.
rrd_info_t was chosen because it was in the output of make when it failed.

That is I saw this error:

See commit b156ce54

Add uid to container_g_add_pid() and container_p_add_pid() functions
Resturcture calls to job container in multiple slurmd/stepd locations

Split container_g_add() into 2 functions, One to add a proctrack
container (PAGG) and a new one to add a PID (which creates the
PAGG and adds the PID to it first.
