This commit adds support for fetch-and-op atomics. This is needed
because and and or are irreversible operations so there needs to be a
way to get the old value atomically. These are also the only semantics
supported by C11 (there is not atomic_op_fetch, just
atomic_fetch_op). The old op-and-fetch atomics have been defined in
terms of fetch-and-op.

This commit renames the arithmetic atomic operations in opal to
indicate that they return the new value not the old value. This naming
differentiates these routines from new functions that return the old
value.

This commit adds a new set of compare-and-exchange functions. These
functions have a signature similar to the functions found in C11. The
old cmpset functions are now deprecated and defined in terms of the
new compare-and-exchange functions. All asm backends have been
updated.

This commit renames the atomic compare-and-swap functions to indicate
the return value. This is in preperation for adding support for a
compare-and-swap that returns the old value. At the same time the
return type has been changed to bool.

Every modern compiler supports either inline assembly or builtin atomic
operations. Because of this it is time to delete all the code associated
with pre-built atomics.
This commit also clean out the DEC and XLC asm checks. Neither check
does anything and the XLC compiler supports GCC ASM.

tests, not OMPI tests.
This allows us to "make distcheck" with "./autogen.sh -no-ompi"
trees (i.e., these tests will now still work even if the OMPI layer is
not present -- because they're OPAL tests and we should treat them
that way).

OMPI_* to OPAL_*. This allows opal layer to be used more independent
from the whole of ompi.

make it maintainer-clean. Neither clean nor distclean should
remove files that were in the tarball...

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

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)

we are part of the source tree and not defined otherwise, we are going
with an always defined if ompi_config.h is included policy. If
ompi_config.h is included before mpi.h or before OMPI_BUILDING is set,
it will set OMPI_BUILDING to 1 and enable all the internal code that
is in ompi_config_bottom.h. Otherwise, it will only include the
system configuration data (enough for defining the C and C++ interfaces
to MPI, but not perturbing the user environment).
This should fix the problems with bool and the like that the Eclipse
folks were seeing. It also cleans up some build system hacks that
we had along the way.
Also, don't use int64_t as the default size of MPI_Offset, because it
requires us including stdint.h in mpi.h, which is something we really
shouldn't be doing.
And finally, fix a ROMIO Makefile that didn't set -DOMPI_BUILDING=1,
as ROMIO includes mpi.h, but not ompi_config.h
