Refactor aggregation code by introducing a single aggr_mode variable and an
enum for aggregation.

Also refactor cpumap code having to do with cpu to socket mappings. All in
preparation for extended modes, such as cpu -> core.

Also fix socket aggregation and ensure that sockets are printed in increasing
order.

It's for calculating whole trace data size during reading.  However
relation functions are called only in this file, no need to
conditionalize it with tricky +1 offset and rename the variable to
more meaningful name like trace_data_size.

Adding automated test for breakpoint event signal handler checking if
it's executed properly.

The test is related to the proper handling of the RF EFLAGS bit on
x86_64, but it's generic for all archs.

First we check the signal handler is properly called and that the
following debug exception return to user space wouldn't trigger
recursive breakpoint.

This is related to x86_64 RF EFLAGS bit being managed in a wrong way.

Second we check that we can set breakpoint in signal handler, which is
not possible on x86_64 if the signal handler is executed with RF EFLAG
set.

This test is inpired by overflow tests done by Vince Weaver.

The perf_evsel__is_group_event function is for checking whether given
evsel needs event group view support or not.  Please note that it's
different to the existing perf_evsel__is_group_leader() which checks
only the given evsel is a leader or a standalone (i.e. non-group) event
regardless of event group feature.
