The opal_gethostname() function provides a more robust mechanism to retrieve the hostname than gethostname(), which can return results that are not null-terminated, and which can vary in its behavior from system to system. opal_gethostname() just returns the value in opal_process_info.nodename; this is populated in opal_init_gethostname() inside opal_init.c. -Changed all gethostname calls in opal subtree to opal_gethostname -Changed all gethostname calls in orte subtree to opal_gethostname -Changed all gethostname calls in ompi subdir to opal_gethostname -Changed all gethostname calls in oshmem subdir to opal_gethostname -Changed opal_if.c in test subdir to use opal_gethostname -Changed opal_init.c to include opal_init_gethostname. This function returns an int and directly sets opal_process_info.nodename per jsquyres' modifications. Relates to open-mpi#6801 Signed-off-by: Charles Shereda <cpshereda@lanl.gov>
