This commit enables the use of opal classes after a call to
opal_class_finalize. This is needed to support re-initializing opal
after calling opal_finalize_util (). This is needed to support the
following without leaking:
MPI_T_init_thread ();
MPI_T_finalize ();
MPI_Init ();
MPI_Finalize ();
Before this commit the above code would crash in MPI_Init because the
constructor array for some class was freed by opal_class_finalize ().
The fix is to turn the cls_initialized member of opal_class_t into an
init epoch identifier and compare it against opal_class_init_epoch
instead of 1. On each call to opal_class_finalize the
opal_class_init_epoch counter is incremented forcing re-initialization
of classes after finalize.

turned out to be a nightmare, as the pointers to the classes are
located in shared libraries memory areas, and are not accesible
after the shared library is unloaded. Thus, OPAL cannot cleanup
the left-over classes from the other shared libraries.

This saves some memory for the constructors and destructors arrays of a
class by counting the constructors and destructors while we are counting
the cls_depth. And the reversion of the constructor array can now be done
without an extra loop.

Windows version for the libevent. The one they provide is more than
innapropriate for what we need (without talking about the fact that
the code is just plain wrong).

the last constructor will be set to NULL overwriting the first destructor. This
prevent us from calling the destructors on some classes.

- 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)

than I want to) on the constructor and destructor loops. Compress the constructors and
destructors array to remove all the useless tests against NULL. Now we use the cache a
little bit more efficient.
Correct a threading problem in the obj_update function. In the threaded case we have to
return the value returned by the ompi_atomic_add function otherwise there are ways
leading to the release of an object twice.

ompi/).
- There's still a handful of places that have orte/ #include files;
still need to clean those up
- A lot of places still use ompi/include/constants.h -- those need to
be converted over to use OPAL_ return codes and then switch to the
opal constants.h. This commit is the first few steps towards
that...
