9fb789dc78 nbis: Update to NBIS 5.0.0
This updates NBIS to its latest 5.0.0 version, dated 04/03/2015, from a
1.x version, dated 2007.

770444af55 nbis: Add script to update NBIS and apply changes
NBIS is pretty complicated to update, seeing as we've made quite a few
changes to get it to compile as a library. With those scripts, we can
easily trim headers to remove functions we don't use, rename global
variables, and do any sort of fixups that are necessary right now.

In the future, removing unused NBIS functions might be as easy as
updating that script, re-running it, and pushing the changes.

Note that remove-function.lua is a very crude parser that only supports
NBIS' style of declaration, with the return type on the same line as the
function name. I wouldn't recommend trying to use it in another project.

Callcatcher (https://github.com/caolanm/callcatcher) was also used to
remove additional unused functions.

75fe328f64 elan: Don't rotate frames on 0x0c03
There has been a report that a 0x0c03 was installed straight (other
readers so far have produced images that are 90 degrees rotated). There
is no way for the dirver to know how a device is installed, so for now just
make an exception.

19e7b217c1 lib: Downgrade fp_err() to be non-fatal
Similarly to b1ac865abd, downgrade
fp_err() to be non-fatal. A number of drivers would spit out an error
when encountering this call, but not crash, carry on and most of the
time recover.

Make sure we don't assert in those cases.

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.

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.

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.
