The newly proposed common DPLL interface discussed on a newsletter[1]
is introducing new, complex subsystem which requires proper integration
testing - this patch adds core for such framework, as well as the
initial test cases. Framework does not require neither any special
hardware nor any special system architecture.

To properly test the DPLL subsystem this patch adds two fake modules,
named 'dpll_test' and 'dpll_test_other'. Only one of them is a subject
for testing, but to rule out the possibility of different behavior based
on the order of modules load the tests are duplicated in multiple
environments:
1) only 'dpll_test' loaded,
2) both 'dpll_test_other' and 'dpll_test' loaded, in this order,
3) both 'dpll_test' and 'dpll_test_other' loaded, in this order.

Patch adds few helper scripts, which are:
1) tools/testing/selftests/dpll/modules_handler.sh˙
    Script is providing a simple way to build, load and unload a
    particular module needed in integration testing - can be used
    standalone
2) tools/testing/selftests/dpll/run_dpll_tests.sh
    Script is checking for all dependencies, creates temporary
    environment, installs required libraries and run all tests - can be
    used standalone
3) tools/testing/selftests/dpll/ynlfamilyhandler.py˙
    Library for easier ynl use in the pytest framework - can be used
    standalone
