Set values to NULL for safety.
Test suite now exits properly.
Fixed debug message qualifiers.
Added missing callsite argument.
Correctly load callsite argument.
Add missing ACL files for text fixture.
added (-c cores) to sge_submit_workers, expliclty recognize --cores all for wq_worker
fix strncmp arguments, have work_queue_worker start as many tasks as it can instead of one per loop in work_for_master()
fixed segfault, adapts the length of time the worker will wait for activity on the link before checking for a missed child completion signal

Consolidates display_mode options

- Changes #defines for enums when declaring unique numbers for long options.
- Removes -Dc and -Ds, instead creating two long options
  --dot-merge-similar and --dot-proportional.
- Dispatches all display_mode options from a single switch statement.
Avoid waiting on a message when workers are available and tasks are in the ready list
Resolves issue #22
Merge branch 'master' of github.com:cooperative-computing-lab/cctools
Incorporates some comments from CRC demo.

Mostly it rearranges columns of the time series, and in the summary it
renames num_processes to total_process and re-renames max_processes to
max_concurrent_processes.
Removes wq in show_help of work_queue_pool.

wq is disabled as a batch system for work_queue_pool, but it was shown
as a possible option for -T.
Instead of tracking the status of the worker pool incrementally, sum it up on demand.
Hopefully addresses issue #29.
