In order to support usersapce access, an event must be mmapped. While there's already mmap support for evlist, the usecase is a bit different than the self monitoring with userspace access. So let's add new perf_evsel__mmap()/perf_evsel_munmap() functions to mmap/munmap an evsel. This allows implementing userspace access as a fastpath for perf_evsel__read(). The mmapped address is returned by perf_evsel__mmap_base() which primarily for users/tests to check if userspace access is enabled.
