Add a quick-load capability to the plugins so that the init() and fini() code aren't invoked if all you want to do is query the plugin type and version.

Previously slurmctld was not filtering out nodes failing to satisfy the
job's mincpus, mem, or tmp constraints.

Add step_id filtering as needed if a user requests info about a step_id
of zero (e.g. 123.0, it used to report all steps for the specified job_id).

 o Fixed fd leak in agent.c using slurm_send_recv_rc_msg() w/ timeout.

Truncate long job names as needed. Do not return an error.

 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
   for use in testing.
 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())

   slurm_protocol_socket_implementation.c
 o Added new functions slurm_send_recv*rc_msg() for handing common
   mode of sending a message and receiving only a "return code" message.
 o Overhauled existing code and performed general cleanup.
