assembling: Fix assembling of last frame in reverse mode
...
The last image is always misplaced because the sign of the delta
vector isn't corrected.
This could result in false positives and verification failing.

assembling: Fix assembling of frames for non-reverse stripes
...
Every frame stores the delta from the previous frame, in reverse mode
it stores the delta to the next frame. This causes images to use the
wrong delta while assembling in forward mode.
The broken assembling in forward mode will create a small error for
linear motion, because the delta of all frames is approximately the
same in this case. But if you move your finger, stop and then continue
moving in a single scan, the misplaced frames should be visible in
the assembled output.
This could result in false positives and verification failing.

lib: Use GLib and libusb directly for debug output
...
Use GLib internally to output debug information, and tell about
libusb's LIBUSB_DEBUG envvar for libusb debug.
fp_set_debug() is now a no-op.

It was here for aes2501 and aes1610 before moving assembling routines
into common code.

lib: use normalized error to make decision about movement direction
...
Height is not a good determinant in movement direction, normalized
error is much better. Should fix aes1610 and aes2501 driver issues.

lib: move frame assembling routines into a separate file and make them usable by non-aes drivers
...
Frame assembling routines are not aes-specific, so move them into a separate file
and add an accessor for peeking a pixel.
