This commit updates btl/vader to use an mpool for handling all shared
memory allocations (frags, fboxes).

This commit adds a new mpool base module type: basic. This module can
be used with an opal_free_list_t to allocate space from a
pre-allocated block (such as a shared memory region). The new module
only supports allocation and is not meant for more dynamic use cases
at this time.

Update the OPAL glue configure code to correctly link the opal/pmix4
component to the hwloc used by OMPI instead of defaulting to the
system-level hwloc. Required a corresponding update to the PMIx hwloc
configure code so we treat hwloc the same way we handle libevent in
embedded scenarios.

The PMIX_MODEX and PMIX_INFO_ARRAY macros were removed from the PMIx 3.1 standard.
Open MPI does not really need them (they are only used to be reported as not supported),
so smply #ifdef protect them to support an external PMIx v3.1

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.

Now Open MPI requires a C99 compiler. Checking availability of
the following types is no more needed.
- `long long` (`signed` and `unsigned`)
- `long double`
- `float _Complex`
- `double _Complex`
- `long double _Complex`
Furthermore, the `#if HAVE_[TYPE]` style checking is not correct.
Availability of C types is checked by `AC_CHECK_TYPES` in `configure.ac`.
`AC_CHECK_TYPES` defines macro `HAVE_[TYPE]` as `1` in `opal_config.h`
if the `[TYPE]` is available. But it does not define `HAVE_[TYPE]`
(instead of defining as `0`) if it is not available. So even if we
need `HAVE_[TYPE]` checking, it should be `#if defined(HAVE_[TYPE])`.
I didn't remove `AC_CHECK_TYPES` for these types in `configure.ac`
since someone may use `HAVE_[TYPE]` macros somewhere.

It seems in some cases (gcc older than v6.0.0) the __atomic_thread_fence is a
no-op with __ATOMIC_ACQUIRE. This appears to be the case with X86_64 so go
ahead and use __ATOMIC_SEQ_CST for the x86_64 read memory barrier. This should
not cause any performance issues as it is equivalent to the memory barrier
in the hand-written atomics.
