RandR (etc) DriverFunc

xf86str.h states that the driver should return FALSE if a driver
function is not supported.

This does not comply with the current use of DriverFunc, namely in
xf86RandR.c. If the driver returns FALSE there, the function calling the
driver function will fail.

So, either we should change the default behavior to return TRUE in the
driver func if the function opcode is not understood by the driver, or
change the existing code not to bail out on FALSE.
