This is only to quite coverity.  I don't think this is a real problem.

Brian approved.

Fix coverity 187747

(i.e. gres=gpu/tesla) it would get a count of 0.

Bug 5570

Note that pipe2() is Linux-specific, but this whole cgroup plugin is
already Linux-specific in design, and the eventfd() call itself is
Linux-specific as well.

Didn't realize centos 6 was so far behind.

Bug5503

"IN" tres_usage is reads
"OUT" tres_usage is writes

page faults are only "ins"

In 18.08 the jobacct_info stats were changed to tres_usage arrays which
are init'ed to INFINITE64 but < 18.08 it was init'ed to 0's.

Bug 5554

In 18.08, usage values are stored as bytes but in <18.08 values were
stored in KB, MB, etc.

Also handle cputime adjustments. Related commit: efc161ef.

In 18.08, VMSIZE is stored as bytes and not kilos anymore.

Related commit: c9448c80

Since cputime isn't stored a double anymore, but as a uin64_t, the
cputime is adjusted so that precision isn't lost.

In 18.08, the stats are stored in TRES arrays and uses the
slurmdb_find_tres_count_in_string() function to return the TRES value.
If a value doesn't exist, the function returns INFINITE64. But < 18.08
is expecting NO_VAL values.

e.g.
A TRES position of INFINTE caused a lappy0 node to be shown -- I don't
have a lappy0.
brian@lappy:~/slurm/master/lappy$ sacct -j 232809 -o MaxVMSizeNode
 MaxVMSizeNode

        lappy0

In 18.08, the usage is stored in a TRES arrays and uses the
slurmdb_find_tres_count_in_string() function to return the TRES value.
If a value doesn't exist, the function returns INFINITE64. But < 18.08
is expecting NO_VAL values.

Turns out if you don't close up everything you open the hdf5 lib doesn't
like that.

Fixs regression in 011b2f23.

avoid copying strings that may be overwritten.

Bug 5547

This has been the default for slurm.conf since 2008, make it the
default for slurmdbd.conf now.

It turns out it is fairly easy with het jobs to hit this and seg fault srun.
