b1ac865abd lib: Downgrade BUG* assertions to work-around crashes 
BUG() and BUG_ON() didn't use to assert, but only print an error if
debugging was enabled. This was hiding a lot of state bugs in drivers,
and transforming those into assertions causes crashes.

Downgrade the assertion to only print a warning, and hope that those
eventually get fixed in the drivers so we can re-enable them.

Closes: #77

056ea541dd poll: Fix fp_get_pollfds retval type 
fp_get_pollfds() is supposed to return a negative value on failure, but
size_t is an unsigned integer. Use ssize_t instead.

c91819f551 lib: Remove drv->close absence support in fp_async_dev_close() 
The driver will at least need to close its hardware resources, and
free memory, so it must have had one.

This case was never actually used as can be seen from the fact that
we would assert in fpi_drvcb_close_complete() if the state was wrong
but never set it to the expected value.

0215483fb3 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.

37bb59df13 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.
