The following set of changes add RDMA CM support to the WinOF stack.
Support is exposed through an OFED librdmacm compatibility library,
which makes use of RDMA CM support through the winverbs library and
driver.

Winverbs now supports QP connection establishment.  Datagram support
in winverbs is still incomplete.

With these changes, it should be possible to support ND above the
winverbs interface with a fairly simple library; although this has
not been done.

A new interface was added to IBAL to export a narrow Infiniband CM
interface that is not tied to the wider IBAL interface and structures.
Although the interface itself is new, an effort was made to minimize
changes to the existing CM code.

In some cases, the patches are fairly large.  To help with code review
new interfaces appear at the top of the patch.

The code was tested using cmatose running between Windows and Linux.
Additional testing was done using a port of the ib_rdma_bw/lat perftests.
