190e7a27cd Merge with gleb-mpool branch. All RDMA components use same mpool now (rdma).
udapl/openib/vapi/gm mpools a deprecated. rdma mpool has parameter that allows
to limit its size mpool_rdma_rcache_size_limit (default is 0 - unlimited).

06563b5dec Last set of explicit conversions. We are now close to the zero warnings on
all platforms. The only exceptions (and I will not deal with them
anytime soon) are on Windows:
- the write functions which require the length to be an int when it's
  a size_t on all UNIX variants.
- all iovec manipulation functions where the iov_len is again an int
  when it's a size_t on most of the UNIXes.
As these only happens on Windows, so I think we're set for now :)

ed83927025 Don't reset the convertor when a persistent request complete. Instead reset it
next time then request is used. This will keep the execution path on the default
case (not persistent) shorter.

688a16ea78 A long time waiting patch. Get rid of the comm->c_pml_procs. It was (and that was
long ago) supposed to be used as a cache for accessing the PML procs. But in
all of the PMLs the PML proc contain only one field i.e. a pointer to the ompi_proc.
This pointer can be accessed using the c_remote_group easily. Therefore, there is no
meaning of keeping the PML procs around. Slim fast commit ...

47725c9b02 * Add new PML (CM) and network drivers (MTL) for high speed
interconnects that provide matching logic in the library.
  Currently includes support for MX and some support for
  Portals
* Fix overuse of proc_pml pointer on the ompi_proc structuer, 
  splitting into proc_pml for pml data and proc_bml for
  the BML endpoint data
* bug fixes in bsend init code, which wasn't being used by
  the OB1 or DR PMLs...

7d1feffbf7 The real solution. If the sendreq->req_send.req_bytes_packed is zero then there
is no data to be trasfered. And this is the condition which lead to a non
initialized convertor.

58cd591d3b PERUSE support for OB1. There we go, now the trunk has a partial peruse implementation.
We support all the events in the PERUSE specifications, but right now only one event
of each type can be attached to a communicator. This will be worked out in the future.
The events were places in such a way, that we will be able to measure the overhead
for our threading implementation (the cost of the synchronization objects).

612570134f The request management framework has been redesigned. The main idea is
to let the PML (or io, more generally the low level request manager)
to have it's own release function (what was before the req_fini). This
function will only be called from the low level while the req_free will
be called from the upper level (MPI layer) in order to mark the request
as not used by the user anymore.

From the request point of view the requests will be marked as inactive
everytime we read their status (true for persistent as well). As 
MPI_REQUEST_NULL is already marked as inactive, the test and wait functions
are simpler. The drawback is that now we have to change in the
ompi_request_{test|wait} the req_status of the request once we get it's
status.

285581dff2 More endian-related cleanups:
- moved hton64 and ntoh64 from the bunch of places it had been copied
    into one header file
  - properly set and use the btl_tcp's nbo option to put things in
    network byte order on the wire if both sides don't have the same
    endianness
  - Put the OB1 PML's headers (with a couple exceptions I need to discuss
    with Tim) in network byte order on the wire if both sides don't have
    the same endianness
  - since it was needed for the TCP BTL, move the orte_process_name_t
    HTON and NTOH macros from the TCP OOB to ns_types.h

45e3415bb5 - With the change from MCA_PML_OB1_FREE in r8945 to the send/recv
counterparts, the reset to MPI_REQUEST_NULL of the upper
   struct ompi_request_t was broken. Nightly mpi_test_suite
   failed, e.g.
   mpirun -np 2 ./mpi_test_suite -t "Ring Isend"

566a050c23 Next step in the project split, mainly source code re-arranging
- 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)

83f83e5730 Specialize the MCA_PML_OB1_FREE macro. When we call this macro we already know what kind
of request we are playing with (send or receive). Therefore, it's useless to have another
switch inside this macro and make the code bigger. Now, we have 2 versions
MCA_PML_OB1_SEND_REQUEST_FREE and MCA_PML_OB1_RECV_REQUEST_FREE.

e9706e6db0 Remove the macro to compute the length of the segments from the send header
and add a new macro that can be used for both sends and receives.
Move to atomic operations to manage the length of the sended or received
status. There is one instance where the atomic operation is not required
as the code can cannot be executed in same time by 2 differents threads.

eb1d2dd290 Working down the latency (0.2 micro-sec on a Xeon 2Ghz) by removing the
second instance of the ompi_proc from the send and receive request. This
information is already available on the base request, so there is no
need for duplication. The drawback is that now (in order to avoid a
second lookup in the communicator array of procs) we have to set the base
proc in the PML's _ALLOC macro.
