On a node with features that change with reboot and static features,
  preserve the static features on reboots

If a job requires features which don't exist on all allocated nodes,
then only reboot the nodes which lack the require features rather
than all allocated nodes.

Get node name prefix and field width directly from actual node names.

Only found would memory leak test configuration

When the acitve or available features for nodes change, alter the
  appropriate lists (with node bitmaps) accordingly

Move the functions from src/common/node_conf.c to src/slurmctld/read_config.c
  and modify the logic to better support active and available feature lists.

If a user specifies KNL features in the configuration, strip them
  out so that we use only the information from capmc

Move reading of knl.conf from src/common/read_config.c into
  src/plugins/node_features/knl_cray/node_features_knl_cray.c
  with minimal changes to logic

First phase of adding node_features plugin infrastructure (taken
  largely from knl plugin infrastructure).
Added node_features/knl_cray plugin.

bug 2408

qalter and qrerun have wrong end-of-line encoding: \r\n rather than \n.

To fix it, please run
sed -e 's/\r$//' -i contribs/torque/qalter.pl
sed -e 's/\r$//' -i contribs/torque/qrerun.pl

Note that these two files have different permission (644) compare to other .pl files (755).
bug 2409

Change some power capping message from debug3 to debug5 if powercapping
  has nothing to do.

Set a job's --test-only start time and resources functioning properly
  with node active/available feature information (i.e. use active
  features if possible and fall-back to whole nodes and available
  features, the whole node flag is needed to insure we can reboot
  the node and change its active features).

Use PRIu64 instead of %ld for uint64_t types (libsh5util_old),
%zu instead of PRIu64 for size_t.

Add macros to fix compatibility for IPv6, deal with
lack of POLLRDHUP on FreeBSD.

Handle difference in cpu affinity APIs in gres.c.
