before checking it with scontrol show job. The test was failing for me
because the job hadn't started yet.

Add BootTime configuration parameter to knl.conf file to optimize resource
    allocations with respect to required node reboots.
Add node_features_p_boot_time() to node_features plugin to optimize
    scheduling with respect to node reboots.

When a buffer packed failed due to invalid message version, a NULL
  pointer was returned, which later resulted in an assert failure.
  This adds a check for a NULL pointer and avoids the assert.

Make it easier to see the 17.02 changes as they are added in.

RPCs will switch to using bit_str_hex for serialization from bit_fmt,
but receivers still need to access this as a inx formatted array for now.
Collapse this into one macro rather than repeating a bunch of times.

Note that this would be better performing if consolidated into a single
function rather than using unpack_bit_str_hex then bitstr2inx to convert;
although this is a client-side function and less important than avoiding
performance and throughput issues within slurmctld.

pack_bit_fmt can exceed 0xfffe characters on large systems and thus
truncate leading to:
"error: Credential signature check: Credential data size mismatch"

Add warning to the pack_bit_fmt macro to highlight issue.

scancel modified to note that no jobs satisfy the filter options when the
    --verbose option is used along with one or more job filters (e.g. "--qos=").
bug 3072

scancel would treat a non-numeric argument as the name of jobs to be
    cancelled (a non-documented feature). Cancelling jobs by name now require
    the "--jobname=" command line argument.

Bug 3395

Replace version borrowed from Linux 2.4.9 with newer version in 4.9.

burst_buffer/cray - Avoid "pre_run" operation if not using buffer (i.e.
    just creating or deleting a persistent burst buffer).
bug 3391

Previous job state information was "PENDING" rather than "REQUEUED"
  for each job requeued due to a burst buffer error.

of before where we could return before we actually used it.

xfree is probably fine in this instance.
