Convert bitmap functions to use int32_t instead of int in data structures
and function arguments. This is to reliably enable use of bitmaps containing
up to 4 billion elements. Several data structures containing index values
were also changed from data type int to int32_t:
- Struct job_info / slurm_job_info_t: Changed exc_node_inx, node_inx, and
  req_node_inx from type int to type int32_t
- job_step_info_t: Changed node_inx from type int to type int32_t
- Struct partition_info / partition_info_t: Changed node_inx from type int
  to type int32_t
- block_job_info_t: Changed cnode_inx from type int to type int32_t
- block_info_t: Changed ionode_inx and mp_inx from type int to type int32_t
- Struct reserve_info / reserve_info_t: Changed node_inx from type int to
  type int32_t

sched/backfill - Prevent possible memory corruption due to use of
bf_continue option and long running scheduling cycle (pending jobs could
have been cancelled and purged).

Change max message length from 100MB to 1GB before generating "Insane
message length" error.

can only be a TORUS (1).

This specifies the maximum depth the backfill scheduler should go
in any single partition.

srun is pending.  The step creation would use the old values and possibly
hang srun since the step wouldn't be able to be created in the modified
allocation.

Add support for "on" and "before*" options

Set PBS_ACCOUNT, PBS_ENVIRONMENT, and PBS_QUEUE only for batch
jobs and only if the user submission sets the account and partition.

No support for PBS "before" options

Caused by allocating single adapter per node of specific adapter type.

Previous logic would pick CPUs then
reject jobs that can not match GRES to the allocated CPUs. New logic first
filters out CPUs that can not use the GRES, next picks CPUs for the job,
and finally picks the GRES that best match those CPUs.
