pthread_create is not a async-signal-safe function, since it can't be
used in a fork (according to POSIX). Calling it may end-up with deadlock
in glibc.

Fix memory leaks from the patch

Bug 7144

If a slurm.conf only has gpu but the gres.conf has gpu:gtx or any other
type we want to remove the type from the gres.conf and use that instead
of forcing the admin to remove the type from the gres.conf.

Quiet NVML init and fini print statements.
Remove two development-only print statements.
Quiet stepd node_config_load print statement.

There is no reason why these should be so loud.

"NVML Library" is redundant.
Add missing env var styling.
Remove awkwardly-placed, duplicated paragraph on MPS in gres.conf man
page. That information is already in gres.html. Also, saying that MPS
is required to be specified in gres.conf is wrong.
Add a reference to gres.html for a more in-depth explanation of GPU
device IDs with NVML.

Add some slurm.conf validation to make sure that typed GRES and
untyped GRES don't mix (e.g. do not allow gres=gpu:1,gpu:tesla:1).

If a configured GPU matches a GPU on the system, match them together.
If a configured GPU has mismatched Cores or Links with the system GPU,
then omit that configured GPU from the final list.

Bug 7517

Move gres_plugin_init_node_config() before
gres_plugin_node_config_load(), so it initializes node_gres_list.
Pass node_gres_list into gres_plugin_node_config_load(), so it gets
the GRES defined in slurm.conf and merges with gres.conf properly.

Bug 7515

Before, data from slurm.conf was only partially merged if there was
no corresponding entry in gres.conf.
Now, Slurm tries to match up gres.conf records to what is defined in
slurm.conf.

Bug 7517

Because the output is alphabetically sorted, "error:" always comes
before "GRES_PARSABLE." Thus, when looking for "WARNING:" instead,
that comes *after* GRES_PARSABLE and can royally mess things up.

The fix is to insulate the output and error regexes from each other by
running them in separate expect loops. This is way more robust and
will guarantee that they never again interfere with each other.

Bug 7517

Create a consistent place for the argument to be specified in tests.

Bug 7517

Add an option to manually disable output sorting and allow extra
logging output.

The problem is that the output is sorted, and is no longer in the
order it printed out. This is confusing when trying to debug the
the test program with an elevated log level.

This is needed to get rid of some "possibly lost" blocks in Valgrind.

Bug 7842.

Increase the maximum array len large to be packed/unpacked with one order of
magnitude, since the current value demonstrated it is not enough when an MPI
program spawns a considerable amount of tasks over a big set of nodes.

This limit was introduced in 627928f4.

Bug 7495

Previous version relayed in the command "time".
It sent STOP and CONT signals and counted time elapsed.
The problem is that defuct childern of stopped parents are not fully
killed, and "time" keep counting time until the actual parent
continue. So, the values were wrong.

The new version uses signal handlers in a .prog and trap in the
shell to print and check if a signal is received.

NOTE: cgroups has different signaling than linuxproc and pgid.

Bug 7282

In previous commit we have double signaling for normal steps
when using --full.
