It seems we can't release accumulate buffers in completion callbacks
because the btls don't release registration resources until after the
callback has fired. The fix is to keep track of the unused buffers and
free them later. This should resolve issues when running IMB-EXT and
IMB-RMA.

Dave Goodell correctly pointed out that it is unusual to return MPI
error classes from internal ompi functions. Correct this in the RMA
case by adding an internal error code to match MPI_ERR_RMA_SYNC.
This does change OMPI_ERR_MAX. I don't think this will cause any
problems with ABI.

I have only checked that these bindings compile without warnings. They
appear to work with both intel's compilers and gfortran.

the user was calling RMA functions correctly.

NOTE: I transferred the oshmem-disabled-by-default from the 1.7 branch to the trunk to minimize future disruption if/when we change that option.

- -check-shmem-params is OFF by default. It checks OSHMEM API params and will abort on bad input
- hcoll do not save fallback coll pointers for unsupported collectives.

The datatype unpacking code assumes that the packed datatype buffer has the
same alignment as an OPAL_PTRDIFF_TYPE. This was not enforced by the rdma
one-sided component. I changed the ordering and sized of various osc/rdma
headers to ensure their sizes are a multiple of 8-bytes and modified the
fragment allocation call to ensure all headers are 8-byte aligned. While
not the cleanest way to handle this situation it should resolve the issue.

assumes the send request is derived from mca_pml_base_send_request_t,
but this is not true for pml cm, so we end up freeing invalid pointer.
We cannot take the data pointer from the pml send request, so we pass
the allocated buffer pointer in req_complete_cb_data, and put the
osc_rdma_module pointer in that buffer as well.
Previously, osc_pt2pt was used with pml_cm which didn't have this
problem.

* Older versions of libusnic_verbs actually return 0 when querying for
an unknown port. So also check for a magic ID in the returned data
to *really* know if the usnic extensions are supported.
* Use a union (in the common_verbs area) and memcpy (in the btl) to
avoid undefined C type aliasing behavior.
* Ensure to memset the function table to 0 if the usnic extensions
are not supported.

When compiling --with-ft there are a few compiler warnings about
unused variables. This patch fixes those compiler warnings.
This commit was SVN r30927.
Realistically, the usnic BTL doesn't need to know anything about the
underlying transport except for its header length (so that it knows
where the payload begins in a received buffer). So remove the use of
the specific transport prefix union and just rely on the usnic verbs
extension to tell us what the header length is if we're using the
usNIC/UDP transport, or sizeof(struct ibv_grh) if we're using usNIC/L2
transport.
This commit was SVN r30914.
Check the IBV_TRANSPORT_* values. In the case of IBV_TRANSPORT_IWARP,
there's an ambiguity and we need to also check to see whether the
usnic verbs externsion probe exists.
This commit was SVN r30913.
If they exist, call the usnic verbs extensions to both enable UDP
support and get the UD receiver header length that should be used
(rather than assume 40/struct GRH).

This allows compilers to know that the code path(s) where
ompi_rte_abort() is invoked won't return (and therefore won't warn in
certain cases).
