tests/testdisplay.c: Add a option '-r'.

Browse Source

With the option '-r', the testdisplay could paint a 2-D bar code(QR
bar code) on the screen. The word "pass" is hiden in the bar code
image.  Further more, with this option, testdisplay will wait until a
system signal 'SIGUSR1' coming after each mode setting. This function
is for another program to control testdisplay.
