o Fix -Wall warnings

 o Move checks for launch or exit timeouts from IO thread into msg.c
 o Added new "undocumented" options --max-launch-time and --max-exit-timeout

 o Do not wantonly terminate IO thread when job moves into state
   TERMINATED, only exit on FORCETERM. (this allows collection of error
   messages from slurmds)
 o Small amount of code cleanup in io.c, signals.c

   (Wait for IO thread even if some IO ops fail)
 o Consilidate redundant slurm_protocol code in mgr.c

 o Temporarily define "dprintf" to avoid using glibc's version (which
   conflicts with version in libmunge) Need to remove this later.

   most of this functionality was provided by slurm_protocol_api.c
   (e.g slurm_send_recv_*_msg())

 o Added new functions slurm_send_recv*rc_msg() for handing common
