If you revoke a credential that has not been used a credential_state object needs to be created

Merge all error functions into slurm_errno.[ch].
Convert error codes from #define to enum.
Add function to slurmctd/locks.[ch] to kill all threads to support
immediate cleanup on fatal error

its place.
Clean up slurmctld termination on fatal events.

Add slurm_addr to node record, set values and send credential revoke.

tasks: purge defunct job table entries, run the scheduler, timeout
jobs, and save state (stub for now).

Restructure some slurmctld code for easier semaphore use.

Changed (removed, added, renamed) configuration parameters.
All config parameters now read from configuration file except
for SLURM_CONFIG_FILE, which comes from config.h

Did some general code clean-up.

Add cpucount by node for resource allocation

Moved around some functions and definitions to make strings
available to API functions and scontrol.

Moved some "shared" node logic to avoid having it overwritten when
moving job config data from API structure.

Fixed numerous minor bugs in job allocation RPCs.
Added numerous job allocation errors.

specified at submit time start with a value of 1<<16 and DPCS uses
values 1 to 0xffffffff. This preclude effective use of a max job_id
in search function, which was able to quickly indicate that a job_id
requested by DPCS was not already in use. I added a job_id hash table
to restore quick job find operations.
Added check of packstr function to insure string would not go over
64k bytes, which is the limit for the protocol used.

and stage_out).

also changed job_scheduler logic for performance. added partition
pointer (in addition to name) in the job records (also for performance).
the scheduler loop was getting bogged down otherwise with (very slow
strcmp calls). execution time of scheduler now almost nil.

	to DPCS with table cross-indecies).
Changed bit_fmt from bit-oriented function to word-oriented for
	dramatic performance improvement, especially with sparce
	bitmap.
Added function bitfmt2int to bits_bytes.c, builds integer array
	from output of bit_fmt for use by DPCS table scans.

Changed use of packstr everywhere (function redefined).

Modified src/api functions to build without warnings, mostly unused
	variables that were declared.
Changed un/packstr into separate unpackstr_ptr and unpackstr_xmalloc,
	the first returns a pointer into the buffer, the second allocates
	memory and copies the string into it.
Converted integers in various job/node/partition structures into
	uint32_t for ease of passing across network with API.

Added definition of build_node_list for task distribution.
Added task distribution code. Added more QA to node_mgr.c and
partition_mgr.c. - Jette

Added scheduler for prioritizing and scheduling pending jobs. - Jette

Added defs for job cancel to header files
Fixed bug in node selection logic, added more logging. - Jette

Added function definitions to slurm.h for allocate (with job tables).
Added support for node allocations via job table entries. - Jette

Updated/added some options in config files for jobs
Added new parse function to bits_bytes.c, defined some new job management
functions in slurm.h
Changed functions to new parse function. Added lots more job management
functionality. - Jette

bits_bytes.c to bitstring.c. Fixed bug in bit_nset function. - Jette

Converted to "safe" memory mamagement routines in xmalloc.c, logging
in log.c, and broke up a couple of larger functions.

coding standards (remove mixed case names, 8 character indents, removed
some comments). Still need to do some work for nesting depth. - Jette
Renamed slurm config files to lower-case names.

defined in slurm.h. - Jette

Added allocate node API (api/allocate.c).
Define allocate node API function in slurmlib.h.
Add support in slurmctld for node allocation API. - Jette

of minimum job node or CPU count. - Jette

Initial version of Makefile.am created for api directory.
API's moved into directory from node_mgr.c and partition_mgr.c (in slurmctld).
bits_bytes moved to common along with headers for API in slurmlib.h.
Semaphores added to node and partition databases. - Jette
