Another step in having all the boilerplate in just one place to then use
in the other tools.

All tools will want those, so provide a convenient way to get them.

Arnaldo Carvalho de Melo 0b495b1215 perf evswitch: Add the names of on/off events 
So that we can have macros for the OPT_ entries and also for finding
those in an evlist, this way other tools will use this very easily.

Arnaldo Carvalho de Melo 8829e56fa0 perf evswitch: Move switch logic to use in other tools 
Now other tools that want switching can use an evswitch for that, just
set it up and add it to the PERF_RECORD_SAMPLE processing function.

Arnaldo Carvalho de Melo d236044272 perf evswitch: Move struct to a separate header to use in other tools 
Now that we see that the simple userspace-based "slicing" of events
using delimiter events ("markers") works, lets move it to a separate
header to make it available to other tools, next step will be having
the switch on/off check done at the PERF_RECORD_SAMPLE processing
function moved too.
