This is a holdover from LAM/MPI that was never implemented here in
Open MPI (and never will be). Might as well remove this dead code.

When querying an info value, copy out exactly as many characters as
the caller asked for -- do not artificially truncate the target just
to ensure that it is \0-terminated.
Specifically: do not use opal_string_copy() to copy info values,
because opal_string_copy() will guarantee to \0-terminate the target,
even if it means truncating the target. E.g., if the caller calls
opal_info_get_nolock() with valuelen=5, opal_string_copy() will return
"1234\0" -- which is wrong. This commit fixes the behavior to return
"12345".

This commit contains the following changes:
- Remove the unused opal_test_init/opal_test_finalize
functions. These functions are not used by anything in the code
base or MTT. Tests use opal_init_util/opal_finalize_util instead.
- Get rid of gotos in opal_init_util and opal_init. Replaced them
with a cleaner solution.
- Automatically register cleanup functions in init functions. The
cleanup functions are executed in the reverse order of the
initialization functions. The cleanup functions are run in
opal_finalize_util() before tearing down the class system.

PR #5241 provided an MCA variable to allow multi-threaded opal_progress.
However, it allowed to update the linked list even when multiple threads was
allowed to call opal_progress. This caused a scenario when a more recent thread
could complete it's progress and fail the assert(sync ==
wait_sync_list).
Allowing to update the linked list only for the case when the number of threads
exceeds the threshold fixes the problem.

-> Added new targets in Makefile.am to call a new build script
generate-opt-funcs.pl to generate specialized functions for
each *.pm file.
-> Added new perl module *.pm files for send,isend,irecv,iprobe,improbe
which are loaded by generate-opt-funcs.pl to create new source files
that correspond to the name of the .pm file to be used as part of
MTL OFI.
-> Added mtl_ofi_opt.pm.template and updated README with details on the
specialization features and how to add additional specialization
support.
-> Added new opt_common/mtl_ofi_opt_common.pm containing common
functions for generating the specialized functions used by
all other *.pm modules.
-> Added new mtl_ofi.h which includes the definitions for the
function symbol table for storing the specialized functions along
with the definitions for the initialization functions for the
corresponding function pointers.
-> Based off the OFI provider capabilities the specialized function
pointers are assigned at mtl_ofi_component_init to the corresponding
MTL OFI function.
-> mca_mtl_ofi_module_t has been updated with the symbol table
struct which is assigned at component init.

For cases when the number of local processes is greater than the number of
available contexts, the SEP initialization phase would calculate the number of
contexts to provision for each rank to be 0 and would eventually crash.
Fix the issue here by using regular endpoints in the event the number of local
processes is more than available contexts. This fixes issue #6182.

- Style it "Signed-off-by" with the quotes and second hyphen everywhere
- Replace "--" with real em-dash characters
- Capitalize "Git" in "Git commits"
- Use an em-dash in the "— The Open MPI Team" sign-off so it doesn't turn in to a one-item bulleted list

pshmem.h now includes shmem.h (since open-mpi/ompi@f46130cd20) and some macros were removed at that time.
Use the OSHMEM_HAVE_C11 macro (defined in shmem.h) instead of the
previous OSHMEMP_HAVE_C11 macrso previously defined in pshmem.h

Commit 109d0569ff introduced a crash when an error occurred
before ofi_ctxt was allocated, including when no providers
passed the selection logic. Properly check that the pointer
is not NULL in the error cleanup code before dereferencing
the pointer.

Though the MPI standard does not have `MPI_CXX_COMPLEX`, `mpi.h`,
`mpif.h`, and `mpi.mod` have it. So I added it for consistency.

This commit fixes edge cases of `r = 38` and `r = 308`.
As defined in the MPI standard, `TYPE_CREATE_F90_REAL` and
`TYPE_CREATE_F90_COMPLEX` must be consistent with the Fortran
`SELECTED_REAL_KIND` function. The `SELECTED_REAL_KIND` function is
defined based on the `RANGE` function. The `RANGE` function returns
`INT(MIN(LOG10(HUGE(X)), -LOG10(TINY(X))))` for a real value `X`.
The old code considers only `INT(LOG10(HUGE(X)))` using `*_MAX_10_EXP`.
This commit adds `INT(-LOG10(TINY(X)))` part using `*_MIN_10_EXP`.
This bug affected the following `p`-`r` combinations.
| p | r | expected | returned | expected | returned |
| :------------ | --: | :-------- | :-------- | :------- | :-------- |
| MPI_UNDEFINED | 38 | REAL8 | REAL4 | COMPLEX16 | COMPLEX8 |
| 0 <= p <= 6 | 38 | REAL8 | REAL4 | COMPLEX16 | COMPLEX8 |
| MPI_UNDEFINED | 308 | REAL16 | REAL8 | COMPLEX32 | COMPLEX16 |
| 0 <= p <= 15 | 308 | REAL16 | REAL8 | COMPLEX32 | COMPLEX16 |
MPICH returns the same result as Open MPI with this fix.
