 o Move autoconf test macros into auxdir directory into separate

it is missing from some versions of SSL.

commands modified. Info filtering added to slurmctld.

* Memory leak in slurm_cred.c, added EVP_MD_CTX_cleanup().
* Pthread stack size too small on AIX. Resulting in stack corruption
  and ugly failure modes. Added slurm_attr_init to macros.h to
  explicitly set the stack size  for all pthreads.
* /dev/urandom not present on AIX, use rand() as needed instead in
  constructing a credential. Used in "srun --join".
* getsockopt(Socket, Level, SO_ERROR, &err, OptionLenght) sometime
  returns an error code of -1. This causes an assert failure in
  slurmd/io.c:_update_error_state().
* Function aliasing is not working on AIX. It is being turned off
  via a variable in config.h and "#if" logic in macros.h and
  slurm_xlator.h.
* dlopen failing if plugins reference any functions not present in
  caller. This may be fixed with the LDFLAG "-Wl,-bgcbypass=1000"
  being added for the slurm commands (avoid garbage collection of
  unused functions).
* read() is sometimes generates EAGAIN error, which was not handled
  in some places.
* vsnprintf() for string NULL is printing "" instead of "(null)"
  as produced by snprintf(). More format printing was added to log.c
  to produce more consistent log messages.
* poll() takes a timeout of -1 for unlimited rather than any negative
  number. Modify logic that was always multiplying by 1000 to convert
  usec to msec.
* getopt_long keyword table was not NULL terminated, resulting in
  segfault with invalid command-line argument in most commands.
* xmalloc module assert failures were not generating a core file.
  Changed "fatal();abort();" to "error();abort();".
* Change msg timeout from 3 sec to 5 sec. Running everything on single
  AIX node was very slow.

 o Fix logic for determination of slurmd and slurmctld port numbers.

loadable as shared aliases. Give slurm functions a prefix of "slurm_" to
insure that no user functions with the same name is used instead.
[For some reason a this same commit a minute ago did not seem to take effect.]

Only attempt to open files having the proper prefix. For example, slurmd
should never even try to dlopen a plugin with a prefix of "jobcomp" as
doing so both wastes time and generates undefined external errors (the
jobcomp plugin is written for the slurmctld daemon and only it has the
proper external function to dlopen that plugin).
