OpenMPI doesn't compile anymore with IME because the header
file "ompi/mca/fs/base/base.h" needs to be include in every
file where mca_fs_base_get_mpi_err() is used.

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.

Some versions of Libfabric contain a bug in EFA where FI_REMOTE_COMM and
FI_LOCAL_COMM are not advertised. In order to workaround this, we need to call
fi_getinfo() without those capability bits to see if EFA is available first.
Also move around some of the provider include/exclude list logic so we can skip
this workaround if applicable.

Make sure to get an RDM provider that can provide both local and
remote communication. We need this check because some providers could
be selected via RXD or RXM, but can't provide local communication, for
example.
Add OPAL_CHECK_OFI_VERSION_GE() m4 macro to check that the Libfabric
we're building against is >= a target version. Use this check in two
places:
1. MTL/OFI: Make sure it is >= v1.5, because the FI_LOCAL_COMM /
FI_REMOTE_COMM constants were introduced in Libfabric API v1.5.
2. BTL/usnic: It already had similar configury to check for Libfabric
>= v1.1, but the usnic component was checking for >= v1.3. So
update the btl/usnic configury to use the new macro and check for
>= v1.3.

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.

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.

Until now sqrt(n) was missed as a factor for odd square numbers n. This
lead to suboptimal results of MPI_Dims_create for input numbers like 9,
