perf cpu_map: Add cpu_map user level event
Adding the cpu_map event to pass/store cpu maps as data in
a pipe/perf.data.
We store maps in 2 formats:
- list of cpus
- mask of cpus
The format that takes less space is selected transparently in the
following patch.
The interface is made generic, so we could add the cpumap event data
into another event in the following patches.
