renamed set_slurm_addr_hton to slurm_set_addr_uint

adjusted arithmetic for packing wrapper routines

   slurmctld.h and api/slurm.h respectively.

   most of the stuff in these files did not belong in common, it has been
   moved elsewhere.

   these are the slurmctld-specific portions of what used to be
   src/common/bits_bytes.h

   what used to be src/common/bits_bytes.c

added pad to slurm_addr type char pad[16 - sizeof ( int16_t ) - sizeof (uint16_t) - sizeof (uint32_t) ] ;
explictly defined IPPROTO_XXX in socket() call

changed sizeof ( slurm_address ) to sizeof ( slurm_addr ) the size of the data type, not the size of the pointer pointing to the datatype

how about using log4c

changed variable type ssize_t in slurm_protocol_api.c to size_t
changed variable type ssize_t in slurm_protocol_api.h to size_t

fixed added set_slurm_addres_hton to slurm_protocol_util.c

had a return type of slurm_fd

Much has changed during development, changes to follow.

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

and stage_out).

Convert between elanid's and hostnames:
 int qsw_getnodeid_byhost(char *host);
 int qsw_gethost_bynodeid(char *host, int len, int elanid);

Send signal to all members of a program description (local operation):
 int qsw_signal_job(qsw_jobinfo_t jobinfo, int signum);

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.
