[PATCH 0/6] tools/kvm_stat improvements

[Stefan Raspl <raspl@linux.vnet.ibm.com>]

Some bugfixes (patches 1&2), simplifications (patch 4), plus rework that
lays the basis for introducing a (hopefully) neater drilldown mode in
patch 7.
Note that in absence of any knowledge of the interdependencies of the
events in debugfs on other platforms like x86, this new 'functionality'
was only added for S390 for now. Adding other platforms would be easy
enough, though.
Furthermore note that the data passing between Providers and Stats is
pretty much at its limit now - if we'd ever wanted to put in more
attributes along with the event data passed from Providers to Stats, we
should probably switch to passing more involved data structures with
indicator flags, etc. Not sure if performance is a concern, but from a
coding/maintaining point of view that's something we should consider in
that case.

Changes in v2:
* Patch [1]:
   - Switched to single underscore prefixing for "private"
     methods.
* Patch [4]:
   - Renamed methods to "tracepoint_is_child" and "debugfs_is_child"
     from "trc_is_child" et al.
   - Also, moved "child_events" and "pid" from DebugfsProvider and
     TracepointProvider up to "Provider".
