Oracle has an interest in a common observability infrastructure in
the RDMA core and ULPs. Introduce static tracepoints that can also
be used as hooks for eBPF scripts, replacing infrastructure that
is based on printk. This takes the same approach as tracepoints
added recently in the RDMA CM.
Changes since RFC:
* Correct spelling of example tracepoint in patch description
* Newer tool chains don't care for tracepoints with the same name
in different subsystems
* Display ib_cm_events, not ib_events
