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

Bug#435

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).

that happens when it gets to the controller anyway.

The ofed plugin doesn't correctly collect packets_in and packets_out.
The ofed plugin treats them as a running total while the hdf5 profile
plugin thinks they are a difference series.

The attached match makes these data items differences.

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

This makes --ntasks-per-socket also available for CR_Core.

Also remove group/other write access to PID file

Also remove group/other write access to PID file

Remove -C option (implemented improperly)
Support multiple -W options (array instead of single option)
Map -l proc option to job constraint
Fix parsing of wall time with colons (avoid breaking into multiple tokens)
