      Add support for AIX systems: · 55e62ab4
      Moe Jette authored
      * 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.
