* 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.la
./lib/libwookie_mpifh.so.0.0.0
./lib/libwookie_mpifh.so.0
./lib/libwookie_mpifh.so
./lib/libwookie_mpifh.la
./lib/libwookie_usempi.so.0.0.0
./lib/libwookie_usempi.so.0
./lib/libwookie_usempi.so
./lib/libwookie_usempi.la
shell$

On some OSs (e.g., Ubuntu 14.04.2 LTS), the linker is configured such
that the symbols of library dependencies are not available to the
application. Hence, we need to explicitly list such dependencies when
creating the executable.
For this commit, these tests are use OPAL function calls, so we must
explicitly link in libopen-pal.so.
Many of these tests were failing due to opal_init() failing in some
cases (because the opal shmem framework needs installed components, so
"make distcheck" would fail these tests because the opal shmem
components were not installed). However, all of these tests seem to
be fine with opal_init_util() -- so let's re-enable these tests.
This commit adds a new class: opal_fifo.h. The new class has atomic, non-atomic,
and opal_using_threads() conditoned routines. It should be used when first-in
first-out is required and should perform much better than using locks and an
opal_list_t. Like with opal_lifo_t there are two versions of the atomic
implementation: 128-bit compare-and-swap, and spin-locked. More implementations
can be added later (LL/SC comes to mind).
This commit also adds a unit test for the opal_fifo_t class. This test verifies
the fifo implementation when using multiple threads.
- Rename opal_atomic_lifo_t to opal_lifo_t to reflect both atomic and
non-atomic usage. Added new routines (opal_lifo_*_st) for non-atomic
usage as well as routines conditioned off opal_using_threads(). The
atomic versions are always thread safe and the non-atomic are always
not thread safe.
- Add a new atomic lifo implementation that makes use of 128-bit
compare-and-swap. The new implementation should scale better with
larger numbers of threads.
- Add threading unit test for opal_lifo_t.
We recognize that this means other users of OPAL will need to "wrap" the opal_process_name_t if they desire to abstract it in some fashion. This is regrettable, and we are looking at possible alternatives that might mitigate that requirement. Meantime, however, we have to put the needs of the OMPI community first, and are taking this step to restore hetero and SPARC support.
the OPAL and ORTE libraries. This is required by projects such as ORCM
that have their own ORTE and OPAL libraries in order to avoid library
confusion. By renaming their version of the libraries, the OMPI
applications can correctly dynamically load the correct one for their
build."

example) because of the fact that libmpi now completely slurps in

* compute mmap-file size more wisely and pass requested size to allocator
* change MCA parameters:
- get rid of mpool_sm_per_peer_size
- get rid of mpool_sm_max_size
- set default mpool_sm_min_size to 0
* no longer pad sm allocations to page boundaries
* have sm_btl_first_time_init check return codes on free-list creations
Have mca_btl_sm_prepare_src() check to see if it can allocate an EAGER fragment
rather than a MAX fragment if the smaller size works.

AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
number to be set at autoconf time (instead of at configure time, as
it was before). Set the version number, minus the subversion r number,
at autoconf time. Override the internal variables to include the r
number (if needed) at configure time. Basically, the right thing
should always happen. The only place it might not is the version
reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
in the directory containing source files, even if the Makefile.am is
in another directory. This should start making it feasible to
reduce the number of Makefile.am files we have in the tree, which
will greatly reduce the time to run autogen and configure.

- Update svn:ignore's to match new exectuable names
- Consolidate the unit test Makefile.am flags into a testing
Makefile.options
- Remove a bunch of SUBDIRS from test/mca/Makefile so that they don't
run by default, but can be invoked manually (they're still in
DIST_SUBDIRS)

For anyone interested, the problem stemmed from two things:
1. a bug in the ompi_bitmap utility (which I copied to orte_bitmap to avoid unintentionally disturbing something else) that causes the bitmap NOT to expand unless the caller asks for a bit that is more than one byte outside the current array size. The unit test didn't pick it up because it doesn't check that close to the boundary.
2. a "feature" in the ompi_bitmap utility that only expands the array if you try to SET a bit outside the current boundary, but NOT if you try to CLEAR a bit outside the array limit. This appears intentional as the unit test checks for this behavior, but I hadn't been expecting the asymmetry.
The orte_bitmap utility now appropriately expands in both circumstances. I also added a function to expand the array so it "covers" a bit location without setting or clearing it. The function allows you to ensure the array is big enough to handle the specified bit, but leave the bit alone if it already is there (the other functions would set/clear it if it was).
I've tested it with up to 100 processes without problem.

OMPI_ENABLE_DEBUG because that changes the size of struct's (e.g.,
ompi_object) in the unit tests as compared to what may have been
compiled in the library.
