In order to support providers that do not handle extensions, including

XRC queue pairs: xrc defines two new types of QPs. The
initiator, or send-side, xrc qp behaves similar to a send-
only RC qp. xrc send qp's are managed through the existing
QP functions. The send_wr structure is extended in a back-
wards compatible way to support posting sends on a send xrc

XRC receive QPs are shareable across multiple processes. Allow
any process with access to the xrc domain to open an existing
QP. After opening the QP, the process will receive events
related to the QP and be able to modify the QP.

XRC introduces several new concepts and structures, one of
which is the XRC domain.
XRC domains: xrcd's are a type of protection domain used to
associate shared receive queues with xrc queue pairs. Since
xrcd are meant to be shared among multiple processes, we

XRC support requires the use of a new type of SRQ.
XRC shared receive queues: xrc srq's are similar to normal
srq's, except that they are bound to an xrcd, rather
than to a protection domain. Based on the current spec
and implementation, they are only usable with xrc qps. To
