This implements Moe's suggestion for NodeAddr/NodeHostname semantics,

   NodeName     "nid#####"    (this is what SLURM will refer to the node as)
   NodeHostName "c0-0c0s0n1"  (Cray's component ID, visible only with scontrol
		                                and sview's node display)
   NodeAddr     "###"         (hexadecimal X, Y and Z coordinates, visible only
		                                with scontrol and sview's node display)

For example,
palu> scontrol show node nid00189
NodeName=nid00189 Arch=XE CoresPerSocket=6
   CPUAlloc=0 CPUErr=0 CPUTot=24 Features=(null)
   Gres=(null)
   NodeAddr=01E NodeHostName=c1-0c0s1n1
   RealMemory=32000 Sockets=4
   ...

Please note:
~~~~~~~~~~~~
on XE systems each two nodes (0/1 and 2/3) on a node share the same network
interface and hence are located at identical Y coordinates in the torus. To
make tools such as smap work with these coordinates, we use "virtual" Y
coordinates, computed as

  y_coord = 4 * cage + cpu;

This scheme mirrors the one currently used to derive node coordinates on a
SeaStar/XT system.

09_Cray-hostlist.diff

This is a global compatibility test to ensure that any (remote) host trying to talk
to a cluster using select/cray meets the minimum requirements of supporting the
required Cray data structures and hooks.

As per previous patches, it may be possible to factor this out, but at this stage
is working code.

06_read_config--test-for-select-cray.diff

If this test is performed on a non-Cray system which tries to talk to 
a remote Cray system, it fails -- which it should not.

This fixes a copy&paste bug where the wrong memory area was dereferenced,
found by these error messages in the logs:

While at it, added tests for the return values of these functions (resv_id

It needs to allocate CPUs, Cores or Sockets too

Updated configure option "--enable-cray-emulation" (still under development) to emulate a cray XT/XE system, and auto-detect a real Cray XT/XE systems (removed no longer needed --enable-cray configure option).  Building on native Cray systems requires the cray-MySQL-devel-enterprise rpm and expat XML parser library/headers.

This disables srun support:
 * on native Cray systems (having 'apbasil' available) it is currently
   not possible, since it would require to have a slurmd on each compute
   node -- which at least at the moment is still done by the ALPS daemons;
 * if running srun from a remote host and trying to launch a job on a remote
   Cray host, the same consideration applies;
 * trying to use Cray-enabled srun (HAVE_CRAY) to launch a job on a non-Cray
   system is allowed to proceed.srun: disable srun on local/remote Cray systems

14_srun.diff

On Cray, wait_job means to confirm the already existing ALPS reservation. This
is handled already:
 * for salloc by select_g_job_ready() - hence no need to call again;
 * for batch jobs it is done in the stepdmanager.
Hence just print a warning to the user.

13_scontrol-no-wait_job.diff

This adds support for execution of salloc on a local Cray system,
disabling node sharing (still not supported on XT/XE).

It further disables running salloc within salloc, as it leads to errors: since
Cray uses process group / PAGG IDs for tracking its reservations, running
salloc from within salloc invariably leads to a ALPS resource allocation error.

Thirdly, it disable Cray node allocation on non-Cray systems, since this
requires that the host on which salloc spawns the shell process is capable
of Cray task launch.

If it is not, then the remote slurmctld will reserve the requested nodes, but
the local host runninc salloc will neither be able to confirm the ALPS 
reservation (due to the absence of a local apbasil command), nor would it be
able to run jobs on the compute nodes.

To distinguish this case from general task launch (we use a frontend host where
salloc could end up running jobs on different clusters, depending on the value
exported via $SLURM_CONF), the following condition is tested:

 * Cray build support has been enabled (HAVE_CRAY);
 * the loaded slurm.conf uses select/cray (required on Cray hosts);
 * the local host does not have support for apbasil (HAVE_NATIVE_CRAY undefined).

Since the 'apbasil' command is only available on native Cray systems, this
combination of conditions seems sufficient to prevent accidentally using
salloc on a host which does not support it.

(For sbatch the case is different, since the job script runs on the remote host.)

11_salloc.diff
done with minor change for Cray emulation

This puts the Basil inventory immediately before each (backfill) schedule. 

Having considered multiple alternatives, this is the most robust and least
wasteful solution. The reason is that ALPS keeps internal node state, which
can be changed
 * by the administrator (xtprocadmin),
 * by the node health checker programs (setting some nodes into 'suspect'),
 * by ALPS itself.

Tracking this periodically, e.g. every HealthCheckInterval, may mean to miss
some state changes. The result would not be a crash, but a subsequently
failed ALPS reservation, which would require to undo some of the slurm state.

Also added inventory to plugin/sched/wiki and wiki2 at get_node time
