completion events after destroying a CQ, QP or SRQ. We do this by
sweeping the event lists before returning from a destroy calls, and
then return the number of events already reported before the destroy
call. This allows userspace wait until it has processed all events
for an object returned from the kernel before it frees its context for
the object.
The ABI of the destroy CQ, destroy QP and destroy SRQ commands has to
change to return the event count, so bump the ABI version from 1 to 2.
The userspace libibverbs library has already been updated to handle
both the old and new ABI versions.

Add structure definition for ClassPortInfo format. This is
needed for (at least) handling CM redirects.

SA: Move SA attributes to ib_sa.h so are accessible to more than
sa_query.c. Also, remove deprecated attributes and add one missing one.

- Add user specified context to all uCM events. Users will not retrieve
any events associated with the context after destroying the corresponding
cm_id.
- Provide the ib_cm_init_qp_attr() call to userspace clients of the CM.
This call may be used to set QP attributes properly before modifying the QP.
- Fixes some error handling synchonization and cleanup issues.
- Performs some minor code cleanup.

Move the InfiniBand headers from drivers/infiniband/include to include/rdma.
This allows InfiniBand-using code to live elsewhere, and lets us remove the
ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles.
