If job involved in dependency completes and is purged the logic
used to test for circular dependencies can use the invalid pointer
and generate an invalid memory reference before the pointer is
cleared from the dependency list data structure.

Without this change, allocations less than a whole node can result
in an incorrect task binding for power7 processors

Without this change, the testing only happens with task/affinity

This bug was introduced in 2.5.2 for the case where a GPU count was
configured, but without device files. Unfortunately it left the
CUDA_VISIBLE_DEVICES environment variable unset if GPUs were configured,
but the job did not request any of them.

This eliminates the need for libnrt.so on the head node.

block, destroy it correctly.

at least 3.5.0.  This avoids a stack overflow when running jobs on
more than 120k nodes.

The new callbacks are not fleshed out, but eliminates a build error

function.
