perf parse-events: Break out tracepoint and printing

Move print_*_events functions out of parse-events.c into a new
print-events.c. Move tracepoint code into tracepoint.c or
trace-event-info.c (sole user). This reduces the dependencies of
parse-events.c and makes it more amenable to being a library in the
future.

Remove some unnecessary definitions from parse-events.h. Fix a
checkpatch.pl warning on using unsigned rather than unsigned int.  Fix
some line length warnings too.

[ Add include linux/stddef.h before perf_events.h for systems where __always_inline isn't pulled in before used, such as older Alpine Linux ]
