increase the previous connection code was broken. It can take as much as 60 seconds to connect
64 processes. Now we do not create the connections when we add the procs but only when we send
them the first message. Now it take only 1.6 seconds to setup a 64 procs MPI job over MX (doing a 2 steps barrier in order to insure that we create all the connections).

* turns out (duh!) that there was a reason that the <projectdir>dir
variable was set in the AM conditional. If not, stupid directories
are created and not needed... duh.

is labeled as internal so the users will not see it but it is not read-only so we can still
play with it (that's for our internal tests). This is supposed to dissapear later after the
next (or next next) release of the MX library, but we need it now as a quick fix before the
release.

- Add big comment about a general overview of what the sm btl is doing
- random small code cleanups
- fix instances of mca_btl_sm[0] to mca_btl_sm[1] where relevant
- remove a lot of unused, confusing, and incorrect interface functions
from ompi_fifo.h and ompi_circular_buffer.h. These functions, if
they were used, would not work properly with the scheme that the sm
btl uses with the fifos (i.e., receiver makes right -- if necessary)
- add some missing offset computations in the fifo and circular buffers
- change the types of offsets to be ssize_t, not size_t
- remove an offset parameter from a function that didn't need it

- Ensure to convert base_shared_mem_flags to be a relative offset in
the global storage, and then to convert that back to an absolute
virtual address before we try to use it
- Don't double increment n_local_procs when calculating the peer rank
during bootstrapping of the different base address case
Something else is still wrong; if mmap() returns a different base
address, things don't work (i.e., segv or hang forever when you try to
send a message). More specifically, the bootstrapping now seems to
correctly handle the case when mmap() base addresses are different,
but the message passing does *not* -- it always assumes that the
mmap() base addresses are the same.
Still working on the fix for that -- want to checkpoint what has been
done so far to facilitate working on different machines...

- first we setup the connections in the begining with all the peers
- MX does not handle well the case where several peers make connections to the same
destination simultaneously.
So I change the order in which we connect. First we compute our rank in the array,
then in a round-robin fashion we setup connection starting with our left neighboard.

larger than 32K for inter-nodes transfert ... and then they do not support iovecs larger than
16K for inter-node transfert. Therefore we have to set the size of our first fragment to
16K to match both cases.

to be supported by mellanox vapi.. perhaps this will be supported in the near
future, for now it doesn't hurt to have it in the trunk
Also cleanup the receive descriptor posting macro's..

Note, we are failing the ring tests in the intel p2p test suite, but we seem
to fail the same tests under the current trunk.. will look into this further.

memory initialization, call opal_progress() to push any pending events
around and possibly yield the processor if nothing entertaining is happening.
This should probably go to the 1.0 branch.

originally suggested by Ralf Wildenhues, to try to speed autogen, configure,
and make (and possibly even make install). Use automake's include directive
to drastically reduce the number of Makefile files (although the number of
Makefile.am files is the same - most are just included in a top-level
Makefile.am). Also use an Automake SUBDIRs feature to eliminate the
dynamic-mca tree, which was no longer really needed. This makes adding
a framework easier (since you don't have to remember the dynamic-mca
tree) and makes building faster (as make doesn't have to recurse through
the dynamic-mca tree)
