Subject: tracepoints: move trace_print_flags definitions to tracepoint-defs.h
The following patch will need to declare array of struct trace_print_flags
in a header. To prevent this header from pulling in all of RCU through
trace_events.h, move the struct trace_print_flags{_64} definitions to the
new lightweight tracepoint-defs.h header.
