checkuninitvar.cpp: Use argument direction "out" info from library cfg ( #1730 )
...
CheckUninitVar::isMemberVariableAssignment uses argument direction "out"
now also to check for assignment when the member variable is handed over
to a function by reference.
testuninitvar.cpp: Improve tests, use a test library configuration.

checkuninitvar.cpp: Use argument direction info from library config. ( #1728 )
...
CheckUninitVar::isMemberVariableAssignment uses argument direction
to check for assignment when the member variable is handed over to a
function by reference. Currently implemented for "in" direction. "out"
will be added with another commit.
