Added pack/unpack functions and additional error codes.

Fixed bit_copy to set magic number.

Modified launch_task message to include stream slurm_addrs and global_task_ids arrays for each task to be launched

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

fixed parsing for this message.

   (macros.h)
 o Include macros.h in slurm_protocol_defs.h

* added commandline parseing to slurmctld
	( I haven't resolved all the problems between read_config )
* changed job_allocate_response_msg to resource_... to reflect the naming scheme better.
* added cpu info to resouce_allocate_response_msg
* fixed slurmctld to return resource allocate messages

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

finished implementation of node_registration_status message that the nodes sent to the controller when they come up

Implemented new slurm_api_init that takes a configuration object containing pri and sec controller address and the default port to connect to

added function docs from c files

node info conversion

Minor cleanup (i.e. comments) on other APIs.

I am implementing the new comm layer in all the api functions
added sockopt parameter SO_REUSEADDR to eliminate socket turn around time during debug.

slurm_protocol_errno.h provides a default place for slurm specific error definitions until Jim completes his general errno implementation

Cleaned up comm layer , this never ends :)
added pack and unpack routines for new communcations paradigm

cleaned up packing and upacking for job_desc
added src/common/log.h include to resolve link warnings

Added a few extra helper funtions

slurm_protocol_api.c			contains the programers interface.
slurm_protocol_interface.h 		defines the lower layer interface.
slurm_protocol_pack.c			packs messages.
slurm_protocol_util.c			contains utility functions used by the protocol
