Bug 5402

Record which GPUs are connected to which via nvlinks.
Determine if each nvlink is single, double, no connect, or self.
Create device index to PCI bus id lookup table.
Fix test 39.18 by reverting parsable prints to always use info().
Add better valgrind support for test 39.18.
Update comments and remove whitespace.

We want the print statements meant for the regression tests to print
out everytime, even if user does not specify debug level.

Auto-detect system GPUs, so no need to specify in gres.conf.
Add ignore syntax to gres.conf.
Test for NVML library existence.
Create tests for GRES GPU code.
Update docs.

Bug 5402

when trying to register.

If slurmd never connects to slurmctld and then slurmd is shutdown,
there is a small memory leak.
This is not an important memory leak; however, this will fix things
for valgrind when testing a slurmd by itself.

Bug 5989

Finish NVLink optimization for all of the new GPU options:
--gpus (per job),--gpus-per-node (or --gres), --gres-per-socket,
and --gres-per-task

without this change, the GRES allocate count on a node will be wrong
if multiple attempts are made to schedule the job

flesh out gpu selection optimization based upon nvlink connectivity whe
the --gpu (per node) specification is used

Set errno to return value of pthread_* functions during error.
All pthread macros now handle errors in the same way.

Do not set errno immediately, because in threaded programs errno is a
macro that expands into a function call. We don't want to incur that
performance cost unless it's actually an error.
See The Linux Programming Interface, 3.5.2 (pg.53) and 29.2 (pg 621).

Bug 5917

Keep the same enum value since this will be the same functional error.

Rename slurm_crypto_type() to slurm_cred_type().

And rename related variables as well.

Rename _slurm_crypto_{init,fini} to _slurm_cred_{init,fini} as well.

All these lengths will need to be packed/unpacked through packmem/unpackmem,
which will needs to handle them as uint32_t anyways.

Start of process to rename CryptoType to CredType.

Bug 5916.

crypto/openssl is removed in the next release. Remove documentation in
the 18.08 release to discourage further use.
