Update slurm.spec as well.

Use of this in the RPC handling code can lead to buffer overflows, as the
size of the destination buffer is not considered when moving data from the
buffer.

Bug 10000.

The calling path into here has already validated the size of the buffer
to unpack from, so (unlike the PMIx usage) this was not overflowable.

But still switch it so we can remove the offending functions.

Update slurm.spec as well.

Update slurm.spec and slurm.spec-legacy as well.

Magic cookie can leak through /proc this way. There is a race here between
this usually short-lived xauth command running and an attacker scraping
the value from /proc. This can be exacerbated through use of
X11Parameters=home_xauthority on a cluster with a shared home directory
under heavy load.

Bug 10056.

This is a breaking RPC change for scrontab.

Ensure flag is always set on scrontab-submitted jobs in job_submit.

Which will make it simpler to add in cli_filter support.

Use libslurmfull since it avoids the slurm_conf_init() call forced as
part of the library init, and nss_slurm specifically does not require
the slurm conf to load.

Without this change, a system without a slurm.conf file will fall back to
hunting for it through the DNS SRV records, and if not found there all
calls into this library will fatal().
