* lttng-event.h declared but did not implement lttng_add_perf_counter_to_ctx
on kernel >=2.6.33, the implementation was in lttng-context-perf-counters.c,
which was only included for kernel >=2.6.34.
This prevented the module from being loaded.
* on kernel 2.6.33.x, lttng-context-perf-counters.c complains about implicit
declaration for {get,put}_online_cpus and {,un}register_cpu_notifier; so
fix header inclusion.
