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.

that it's a directory. That's good enough to know that the
OpenFabrics kernel drivers have been loaded. If you have no RDMA
devices and don't want to see the OMPI warning about not finding any
devices, then don't start the OpenFabrics kernel drivers.

non-empty. If not, then exit the openib btl silently. This addresses
the case where libibverbs is installed (which is getting more common)
and therefore the openib BTL was built/installed, but the kernel
drivers are not loaded (assumedly because there is no RDMA hardware
present). In this case, "mpirun a.out" will not issue a warning.
There appears to be no good way to definitely tell if there are no
RDMA hardware devices present. For example, if libibverbs/the openib
BTL is installed, there are no RDMA devices present, but the RDMA
hardware kernel drivers ''are'' loaded, OMPI will warn that it was
unable to find suitable devices. This warning is easily eliminated by
unloading the kernel drivers.
