Added new internal Slurm functions xmalloc_nz() and xrealloc_nz(), which do
not initialize the allocated memory to zero for improved performance.

super heavy systems to be able to only commit every once in a while instead
of after every transaction.  This is much faster, but can introduce a very
small window in which if something happens that makes the slurmdbd end
irregularly some data loss is possible.

it is much faster than doing a commit every time.

switch/nrt - Do not explicitly unload windows for a job on termination,
only unload its table (which automatically unloads its windows).

error...

error: '0' flag ignored with '-' flag in gnu_printf format [-Werror=format=]
    printf("%0-*llX ", abs_len, (long long unsigned) value);

There is probably be better way to fix it, I just wasn't sure how.

levels of accounts with fairshare=parent

fairshare=parent

in the association tree with fairshare=parent

is set or details ptr isn't on the job.

_apply_priority_weights() back to _get_priority_internal() and have that
function call _set_priority_factors instead of having that called outside
of the function.

This also makes it so _set_priority_factors isn't called on jobs with
direct_set_prio or jobs's without a details ptr.

lost should the slurmctld restart.

uses SelectType=select/cons_res otherwise don't send the
request to slurmctld and return an error.
