0dfceeffae tools lib traceevent: Move kernel_stack event handler to "function" plugin. 
The "kernel_stack" event handler does not depend on any trace-cmd
context, it can be used aside from the application. The code is moved to
libtraceevent "function" plugin.

5786362332 tools lib traceevent: Add offset option for function plugin 
When the offset option is set for the function plugin enabled, it will
display the offset of the functions along with their names.  This helps
in finding exactly where a function was called by its parent.

  trace-cmd report -O parent -O offset

077faf3dc7 libtraceevent: Move traceevent plugins in its own subdirectory 
All traceevent plugins code is moved to tools/lib/traceevent/plugins
subdirectory. It makes traceevent implementation in trace-cmd and in
kernel tree consistent. There is no changes in the way libtraceevent and
plugins are compiled and installed.

Committer notes:

Applied fixup provided by Steven, fixing the tools/perf/Makefile.perf
target for the plugin dynamic list file. Problem noticed when cross
building to aarch64 from a Ubuntu 19.04 container.
