Some minor changes to help facilitate debugger support so that both mpirun and yod can operate with it. Still to be completed.

is still to use the C based wrapper compilers (which have many more features
and are more well tested). The Perl compilers are enabled with the option
--enable-script-wrapper-compilers, which also ignores the option
--disable-binaries (ie --enable-script-wrapper-compilers --disable-binaries
will result in perl-based wrapper compilers being installed, but no other
binaries being installed).

a standalone library named libopenmpi-malloc. Users wanting to
use leave_pinned with ptmalloc2 will now need to link the library
into their application explicitly. All other users will use the
libc-provided allocator instead of Open MPI's ptmalloc2. This change
may be overriden with the configure option enable-ptmalloc2-internal
- The leave_pinned options will now default to using mallopt on
Linux in the cases where ptmalloc2 was not linked in. mallopt
will also only be available if munmap can be intercepted (the
default whenever Open MPI is not compiled with --without-memory-
manager.
- Open MPI will now complain and refuse to use leave_pinned if
no memory intercept / mallopt option is available.

This commit repairs the debugger initialization procedure. I am not closing the ticket, however, pending Jeff's review of how it interfaces to the ompi_debugger code he implemented. There were duplicate symbols being created in that code, but not used anywhere. I replaced them with the ORTE-created symbols instead. However, since they aren't used anywhere, I have no way of checking to ensure I didn't break something.
So the ticket can be checked by Jeff when he returns from vacation... :-)

After much work by Jeff and myself, and quite a lot of discussion, it has become clear that we simply cannot resolve the infinite loops caused by RML-involved subsystems calling orte_output. The original rationale for the change to orte_output has also been reduced by shifting the output of XML-formatted vs human readable messages to an alternative approach.
I have globally replaced the orte_output/ORTE_OUTPUT calls in the code base, as well as the corresponding .h file name. I have test compiled and run this on the various environments within my reach, so hopefully this will prove minimally disruptive.

We already show_help when we fail to create queues, so I just made the
message a little more verbose such that it may be that OMPI is trying
to use a feature that is not supported on the hardware.

1. The send path get shorter. The BTL is allowed to return > 0 to specify that the
descriptor was pushed to the networks, and that the memory attached to it is
available again for the upper layer. The MCA_BTL_DES_SEND_ALWAYS_CALLBACK flag
can be used by the PML to force the BTL to always trigger the callback.
Unmodified BTL will continue to work as expected, as they will return OMPI_SUCCESS
which force the PML to have exactly the same behavior as before. Some BTLs have
been modified: self, sm, tcp, mx.
2. Add send immediate interface to BTL.
The idea is to have a mechanism of allowing the BTL to take advantage of
send optimizations such as the ability to deliver data "inline". Some
network APIs such as Portals allow data to be sent using a "thin" event
without packing data into a memory descriptor. This interface change
allows the BTL to use such capabilities and allows for other optimizations
in the future. All existing BTLs except for Portals and sm have this interface
set to NULL.

Also fast pathed the matching for small fragments.
