Due to current design the job limits are checked before the allocation is
made when one specifies a generic gres and a specific gres type is configured.
The workaround for now is to define a job submit plugin to control the user
request and succesfully apply limits.

Bug 5108

Turns out the partititon's billing tres was working off the sum of
the node_ptrs which contain the max of all partitions they are in.

This isn't correct since each partition's billing can be different.

Set it correctly here.

These functions are not async-cancel-safe, and cannot safely be cancelled.
This leads to potential deadlock, either between our own locks, or deep
inside glibc when the thread held a malloc arena lock when canceled.

Replace with pthread_signal to the appropriate cond to
wake threads up at the appropriate time instead.

This allows the suspend script to be triggered even if Slurm has the
node(s) in a power_save state.

Bug 5053

When any of these --exclusive modes couldn't be satisfied, Slurm was
returning an incorrect ESLURM_NODE_NOT_AVAIL, having as a consequence
scheduling problems as described in the bug. The fix makes it so the
error code is properly set to ESLURM_NODES_BUSY, fixing also the
scheduling problems and working over the correct share_node_bitmap.

Fix an issue in the bit manipulation log introduced in commit 892ffa89.

Bug 4997.

Replace select_p_select_jobinfo_sprint() with the same NO-OP
that the other plugins (except alps and bluegene) have implemented.

Bug 5077.

1. Identifies nodes which are unavailable to a specific job,
adding a call to filter_by_node_owner() in select_nodes()
 where the node list is generated.
2. Removes the "unavail_node_str" argument to select_nodes()
as it is no longer useful. This string originally was originally
generated once at the start of the job scheduling logic for all jobs,
but since each job can have a different set of
 unavailable nodes (dedicated to user, group, etc.)
so the same string for all jobs can be misleading.

If an update for a job that is being requeued[hold] happens, we don't want
to modify the start_time of the old record. Pending + Completing is

job_ptr was still being referenced after releasing the read locks. Also
prolog_running_decr() needs to have a job write lock and a fed read
lock.

Bug 4990.

While restarting slurmctld with -R flag, features were emptied.
This patch just does nothing when recover=2 (-R) which means active and
available features are preserved from the state files. Needed for
backup slurmctld controller.

If block_map_size is zero (as seen on FreeBSD when not using HWLOC),
xmalloc(0) will return NULL. Writing to str[0] then is invalid.
