livibverbs: Add support for XRC SRQs
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
support xrc srq's, we define a new srq_init_attr structure
to include an srq type and other needed information.
The kernel ABI is also updated to allow creating extended
SRQs.

libibverbs: Introduce XRC domains
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
introduce new APIs to open/close xrcd's.
The user to kernel ABI is extended to account for opening/

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.
