    reftests: Add reftest for direction change
    
    This reftest makes use of the new feature to add signal handlers.
    
    It adds a libreftest.so module containing all the code for the reftests.
    When adding a test named reftest.ui, please keep code contained in a
    source file names reftest.c and add that file to Makefile.am.
