fix some of the multi-threading problems for the cid allocation. Two bugs
specifically:
- since we do not have a queue for incoming fragments of unknown cid, we need
to synchronize all processes before exiting the communicator creation. This
synchronization was/is located in comm_activate, which was however too late
for the multi-threaded case. Thus, for multi-threaded scenarios we are now
synchronizing 'before' we allow another thread to enter the cid-allocation
loop.
- for synchronization, we used for the sake of simplicity allreduce
operations. It turns out, that these operations interefered with the
allreductions in the cid-allocation routine, which lead to non-sense results
in the cid-allocation and potentially to endless loops.
Multi-threaded communicator creation seems to work now, is however still 'very
very' slow. I think, the busy wait of threads is killing the performance of
the active threads in the cid allocation. But this is another topic.

with Libtool 2.1a versions prior to the lt_dladvise code. Autogen

only static libraries. Previously, we were linking the libraries into
directly into the common, btl, and mtl code. This seemed to work fine
for me on my Opteron Fedora box, but caused Lisa some issues (PtlNIInit
would succeed, but the network handle would fail when used with
PtlEQAlloc).
Instead, link the portals libraries directly into libmpi and not at
all into the common, btl, or mtl components. THen use some linker
tricks to force the linker to bring in the public interface for the
reference implementation (which thankfully is pretty small).

You can specify --with-udapl on the configure command line (on any OS)
to force OMPI to try to configure/build udapl (i.e., look for udapl's
header/library files, etc.).

Without this fix, a NULL segment pointer could make it past the
