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.

2. Add request for output from `git submodule status` when

Allow the user to override the modulefile_path (root directory to
install the Open MPI modulefile), even if install_in_opt==1. For
example:
rpmbuild \
--rebuild \
--define 'install_in_opt 1' \
--define 'modulefile_path /path/to/my/modulefiles/openmpi/%{version}' \
openmpi-4.0.2-1.src.rpm

Rename the component to be "hwloc2" (since it can now be any v2.x.y
version of hwloc), and make the embedded copy of hwloc be a git
submodule.

Clarify in README what --with-hwloc does in its different use cases.
Also, ensure that the behavior when specifying `--with-hwloc` is the
same as if that option is not specified at all. This is what we did
in Open MPI <= v3.x; looks like we inadvertantly caused `--with-hwloc`
to be synonymous with `--with-hwloc=external` in v4.0.0.

Change the provider include and exclude list name comparison check to
ignore case. The UDP provider's name is uppercase and was being selected
despite being in the exclude list.

Squash compiler warning due to whitespace/brace problems.
The code block from lines 829-839 was improperly indented, which led to
both the code being confusing and a compiler warning. Comparing this code to
the current version in the MPICH repo made it clear that the code was simply
improperly indented. Fixing the indentation both makes the code readable and
squashes the compiler warning.

ROMIO is third-party software but has an annoying compiler warning;
this is the minimum distance fix.

I removed the implementation and/or prototypes of all unused functions defined for all components.
To reduce recurrent code, I created functions under base for the management of error codes and setting of file permission and amode.
Then, I replaced these recurrent code by those function for all components.

When O_CREAT and O_EXCL are set, open() shall fail if the file exists. Therefore, I assigned the file creation to the root process only.
I also translated the errno codes to their corresponding MPI error codes.
