Michael Margolin b3818ea4ad RDMA/core: Add Completion Counters support ...

Add core infrastructure for Completion Counters, a light-weight
alternative to polling CQ for tracking operation completions.

Define the UVERBS_OBJECT_COMP_CNTR ioctl object with create, destroy,
modify and read methods for both success and error counters. Add a QP
attach method on the QP object to associate a completion counter with a
queue pair.

Add ib_comp_cntr struct, ib_comp_cntr_attach_attr, device ops, and
DECLARE_RDMA_OBJ_SIZE for driver object allocation.

Only userspace Completion Counters are supported at this stage.
