[RFC] kernel tests parameters change

[Michal H. <ms...@gm...>]

Attached patch changes current behavior of test binary parameters.
Original implementation didn't allow specifying concrete tests by
parameters.

The new one provides following semantics:

./kernel_tests [-all] [-dir test_directory] [filename]* [test_name]*

where 
	-all means that also debug messages are printed
	-dir test_directory sets directory with test files
	[filename]* zero or more test files (regular file)
	all other parameters which don't fit into those for above
	parameters.
