de1764892a perf session: Keep pointers to the vmlinux maps 
So that tools such as 'perf probe' don't have to lookup
'[kernel.kallsyms]' but instead access them directly after
perf_session__create_kernel_maps or
map_groups__create_kernel_maps.

55aa640f54 perf session: Remove redundant prefix & suffix from perf_event_ops 
Since now all that we have are perf event handlers, leave just
the name of the event.

31d337c4ee perf session: Move total_unknown to perf_session->unknown events

d549c76901 perf session: Remove sample_type_check from event_ops 
This is really something tools need to do before asking for the
events to be processed, leaving perf_session__process_events to
do just that, process events.

Also add a msg parameter to perf_session__has_traces() so that
the right message can be printed, fixing a regression added by
me in the previous cset (right timechart message) and also
fixing 'perf kmem', that was not asking if 'perf kmem record'
was ran.

4aa6563641 perf session: Move kmaps to perf_session 
There is still some more work to do to disentangle map creation
from DSO loading, but this happens only for the kernel, and for
the early adopters of perf diff, where this disentanglement
matters most, we'll be testing different kernels, so no problem
here.

Further clarification: right now we create the kernel maps for
the various modules and discontiguous kernel text maps when
loading the DSO, we should do it as a two step process, first
creating the maps, for multiple mappings with the same DSO
store, then doing the dso load just once, for the first hit on
one of the maps sharing this DSO backing store.

Also move the event_ops definition to session.h, starting to

94c744b6c0 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.
