Stefan Seyfried 33629504fa implement getWidth4FB_HW_ACC in fb_accel class
This helper to determine alignment for hardware blitting is now in
system/helpers.h, where it does not really belong. Put it into the
framebuffer class instead. Framebuffers that don't need it will just
get a dummy function, the cs_hd2 framebuffer gets the real thing.
Also add a bool function that indicates the need for alignment.
