the class system can be initialized/finalized as many times as we like,
so there is no more need to have opal_class_finalize() invoked in a destructor

libnl and libnl-3 are known to conflict with each other, so detect
and abort if these two libs are both used directly (e.g. Open MPI
uses libnl-3) or indirectly (e.g. libibverbs.so might depend on libnl)
* Add a configure time option to rename libmpi(_FOO).*
- `--with-libmpi-name=STRING`
* This commit only impacts the installed libraries.
Internal, temporary libraries have not been renamed to limit the
scope of the patch to only what is needed.
For example:
```shell
shell$ ./configure --with-libmpi-name=wookie
...
shell$ find . -name "libmpi*"
shell$ find . -name "libwookie*"
./lib/libwookie.so.0.0.0
./lib/libwookie.so.0
./lib/libwookie.so

./lib/libwookie_mpifh.so.0
./lib/libwookie_mpifh.so

Newer versions of gcc have "poisoned" the __malloc_initialize_hook
name and it can no longer be used. Added a configure check and
protection around its usage.

These macros should really be named OPAL_SUMMARY_*; they're used in
all projects, and therefore should be in the lowest later project (OPAL).

This commit adds two m4 macros: OPAL_SUMMARY_ADD, OPAL_SUMMARY_PRINT.
OPAL_SUMMARY_ADD adds an item to a section in the summary. For example
OPAL_SUMMARY_ADD([[Transports]],[[Foo]],...,[yes]) will add the
following to the summary:
Transports
-----------------------
Foo: yes
With this commit two sections are added: Transports, Resource Managers.
The OPAL_SUMMARY_PRINT macro is called after AC_OUTPUT and prints out
some information about the build (version, projects, etc) and then
the summarys sections. It will additionally print a warning if
internal debugging is enabled.
Example output:
Open MPI configuration:
-----------------------
Version: 3.0.0 a1
Build Open Platform Abstration project: yes
Build Open Runtime project: yes
Build Open MPI project: yes
Build Open SHMEM project: no
MPI C++ bindings (deprecated): no

This commit removes the --with-mpi-thread-multiple option and forces
MPI_THREAD_MULTIPLE support. This cleans up an abstration violation
in opal where OMPI_ENABLE_THREAD_MULTIPLE determines whether the
opal_using_threads is meaningful. To reduce the performance hit on
MPI_THREAD_SINGLE programs an OPAL_UNLIKELY is used for the
check on opal_using_threads in OPAL_THREAD_* macros.
This commit does not clean up the arguments to the various functions
that take whether muti-threading support is enabled. That should be
done at a later time.

counting or not the collective traffic as a separate entity. The need
for such a PML is simply because the PMPI interface doesn't allow us to
identify the collective generated traffic.
The Makefile.ompi-rules trim options previously used AM_CONDITIONALs
that were defined only when the OMPI project was configured. Hence,
if you ran "autogen.pl --no-ompi", autogen would fail with lots of
messages about undefined AM_CONDITIONALs.
This commit makes new AM_CONDITIONALs outside of the project
configuration that can be safely used elsewhere.
This commit does two things. It removes checks for C99 required
headers (stdlib.h, string.h, signal.h, etc). Additionally it removes
definitions for required C99 types (intptr_t, int64_t, int32_t, etc).

Per Paul Hargrove's email
(http://www.open-mpi.org/community/lists/devel/2015/04/17310.php),
there were a few typos in the message displayed when flex is not
found. Additionally, somehow it didn't show the list of *.l files on
his system. This is not a super-important message -- so just take
that "find" out (and force developers to install flex).
This commit is related to an RFC from June 2014. Disscussion can be

The finalize function is set using either the linker option -fini or
__attribute__((destructor)) depending on compiler support. I have
confirmed that this hybrid approach works with all the major
compilers. The attribute is supported by gcc, clang, llvm, xlc, and
icc. The fini function will support pgi. If a compiler/linker
combination does not support either the destructor or fini function a
message will be printed on re-init indicating it is not supported (an
improvement over the current behavior-- SEGV).
I moved the following to the destructor function:
- Class system finalize. This solves a bug when MPI_T_finalize is
called before MPI_Init. The only downside to this change is we will
leave the footprint of the opal class system after
MPI_Finalize. This footprint should be relatively small.
This is an alternative to #517 but the two PRs are not
mutually-exclusive (with some modifications). This commit should also
be safe for 1.8.x as it does not change internal or external ABI (#517
changes internal ABI).

OMPI *requires* a C99 compiler, so we don't need the AC_C_INLINE or
AC_C_RESTRICT tests anymore (because the C99 compiler guarantees to
support them). Indeed, in some cases (see open-mpi/ompi#491),
AC_C_INLINE gets the wrong answer and defines `inline` to be empty,
which screws up some systems (e.g., OS X with clang).
As an added bonus, we get to get rid of a bunch of gcc 2.96-specific
code (!) in configure.ac.
Trivial change to an output message, just so that github and emacs
syntax hilighting does not get confused (and think that the ' in don't
is an unterminated single quote).
A 128-bit compare-and-swap will enable a better atomic lifo implementation
that uses the pointer + counter method to avoid ABA issues. This commit
adds configury to check for the instruction (cmpxchg16b) and adds an
implementation that uses the __int128 type available in C99.
Add an alps common lib to orte. Add a function
to determine whether or not a process is in a
PAGG container.
Note: we need a better naming convention for
common libs, since right now they use a "flat"
naming convention.
