It turns out that the approach of having the HNP do the
fork/exec of MPI ranks on the head node in a SLURM environment
introduces problems when users/sysadmins want to use the SLURM
scancl tool or sbatch --signal option to signal a job.
This commit disables use of the HNP fork/exec procedure when
a job is launched into a SLURM controlled allocation.

The `ompi_comm_set` function never sets `NULL` to its first argument
`ncomm`. So `NULL` check is unnecessary in its callers. Furthermore,
`NULL` check may obscure a real return code when an error occurs
if the variable is initialized to a `NULL` value.
Also, `NULL` check is added in the `ompi_comm_set` function to
avoid segmentation fault in an out-of-memory condition.

Per discussion at the Summer 2017 developers meeting, generate
the AUTHORS list at make dist time, rather than trying to
keep it up to date and merge on the branches by hand. While
most of the data is generated from git, the organization list
was maintained by hand. The general feeling at the meeting was
that the organization list was not adding value and there were
concrete cases where it involved much chasing by the RMs, so
it has been removed.

This changes the default to 0, to avoid yields during progress in srun.
In mpirun, ompi_mpi_yield_when_idle is set to 1 if oversubscribed
otherwise 0. But the default is 1 though, and it is used in srun.
Now srun and mpirun have the same latency in non-oversubscribed cases.
