Thomas Martitz 6630958533 lcd-common/scroll_engine: Introduce lcd_putsxy_scroll_func(). 
This function supports installing a custom scroll callback. This will be
called when the scrollengine redraws the line. It allows to draw extended
styles (or anything your can possible imagine) along with the text.

It is also strictly pixel-based, the first pixel-based function that supports
scrolling.
