Without this patch running ring_c with the usnic BTL under valgrind will
cause the orteds to segfault.

Without this, an attribute copy function could return non-success, but
it would not be propagated upwards. This caused the intel
MPI_Keyval3_* tests to fail.

When you call MPI_Graph_create with a old_comm of size N, and pass
nnodes=(N=1), then the Nth proc is supposed to get MPI_COMM_NULL out.
The code in this base function didn't properly handle the proc(s) that
are supposed to get MPI_COMM_NULL out.

Using MAP_ANONYMOUS brings different interpretation of fd, offset arguuments of mmap()
Linux:
The mapping is not backed by any file; the fd and offset arguments are ignored.
Mac:
Map anonymous memory not associated with any specific file. The offset argument is
ignored. Mac OS X specific: the file descriptor used for creating MAP_ANON regions
can be used to pass some Mach VM flags, and can be specified as -1 if no such flags
are associated with the region
FreeBSD:
Map anonymous memory not associated with any specific file. The file
descriptor used for creating MAP_ANON must be -1. The offset argument must be 0.

To accompany r31092 and r310924, also ensure to create a new process
group in the child right after the orted forks. Add trivial configury
to ensure that we have setpgid, and only do the setpgid/getpgid if we
have setpgid.
Without this commit, killing the entire process group can do
unexpected things (e.g., kill the orted, mpirun, and even mpirun's
parent!).

This isn't causing any errors that I know about but it does fix an
annoying valgrind warning. Simple fix, no review required.

There are situations where coll/ml does not initialize properly. These will
eventually need to be fixed but in the meantime it is better to not always
print an error message because the collective framework can still fall back
on another collective module. This commit reduces the verbose output.

It is usually not a good idea to assert when something is not implemented
or something goes wrong. Replace asserts with debug output and return.

The necessary information is stored in the proc object. There is no need
to allgather the local process data to determine if another rank is on
the same socket.

After discussion with Manju we decided to update these the process count

* Ensure that all endpoints[x] values are initialized to NULL
* If ibv_create_ah fails, remove each endpoint from the

properly.

opal-restart.c disables crs module selection by setting
crs_base_do_not_select to true using opal_setenv() before
opal_init(). After opal_init() it enables module selection
by changing the variable back to false using opal_setenv().
This does not work anymore as the variables are only read
from the environment during variable registration.
This changes the second opal_setenv() to mca_base_var_set_value()
