perf tools: Introduce perf_session class
That does all the initialization boilerplate, opening the file,
reading the header, checking if it is valid, etc.
And that will as well have the threads list, kmap (now) global
variable, etc, so that we can handle two (or more) perf.data files
describing sessions to compare.
