e19777e910 A more consistent version. As we now share the send and receive queue, we
have to construct/destruct only once. Therefore, the construction will
happens before digging for a PML, while the destruction just before
finalizing the component.

Add some OPAL_LIKELY/OPAL_UNLIKELY.

84d1512fba Add the potential for doing some basic error checking on mutexes during
single threaded builds.  In its default configuration, all this does
is ensure that there's at least a good chance of threads building
based on non-threaded development (since the variable names will be
checked).  There is also code to make sure that a "mutex" is never
"double locked" when using the conditional macro mutex operations.
This is off by default because there are a number of places in both
ORTE and OMPI where this alarm spews mega bytes of errors on a
simple test.  So we have some work to do on our path towards
thread support.

Also removed the macro versions of the non-conditional thread locks,
as the only places they were used, the author of the code intended
to use the conditional thread locks.  So now you have upper-case
macros for conditional thread locks and lowercase functions for
non-conditional locks.  Simple, right? :).

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 ...

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.

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.
