o added section glossing over job initiation design and corresponding
   figures.

Modified print method to print to a file descriptor instead of stdout.

correct warning in qsw.c

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

Completely reimplemented controller.c top to bottom to accomidate the new comm layer

comm layer method of doing things

these probably need a permanent home some where else.

We should not duplicate definitions in api/slurm.h and slurmctld/slurmctld.h

unpacks for client side info calls in progress

  "processes" not "processors").
* fix some dry coding errors in step_mgr.c found when compiling after
  configure --with-elan

Changed a couple of names in the qsw.c api:
 qsw_prog_reap -> qsw_prgdestroy (since it's just a wrapper for rms_prgdestroy)
 qsw_attach -> qsw_setcap (since it's just a wrapper for rms_setcap)
 qsw_signal_job -> qsw_prgsignal (since it's just a wrapper for rms_prgsignal)
Added a conditional include of qsw.h to slurmctld.h so it would compile
when configured --with-elan.
