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.
Sensor reset code has been removed because it is not needed during normal
operation.
Calibration and frame processing logic has been improved according to
recommendations from Elantech.
Make each command a separate struct to get finer control over which
commands are called on which devices. Update ssm's accordingly. Add
sensor_reset and fuse_load commands.
Support 0x0903, 0x0c03, 0x0c16, 0x0c1a, 0x0c26
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.
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
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.
Which avoids passing zero lines to fpi_assemble_lines()

See https://bugzilla.redhat.com/show_bug.cgi?id=1484812Closes: #42
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.
https://bugs.freedesktop.org/show_bug.cgi?id=105027
aeslib.h and assembling.h don't need access to internal data structures,
so make them include the public fprint.h rather than the internal header
fp_internal.h.
This time, the macro didn't wrap the condition, resulting in calls
like BUG_ON(size > 100) being expanded to g_assert(!size > 100), when
what we wanted was BUG_ON(!(size > 100)).
See 9cca501650,
ff09456cf5, and egg on my face.
Remove deprecation warning that comes from an internal function, it

Remove all the headers already included through "fp_internal.h" such as
<libusb.h> and <errno.h>, include "assembling.h" and "driver_ids.h" there
as well to avoid doing it in (almost) every driver.
As this is pretty much copy/pasted in fprintd, and should instead be
implemented by whatever system actually stores the data, rather than
in a generic but not quite "fits-all-purpose" way.
https://bugs.freedesktop.org/show_bug.cgi?id=106550
Instead of having to modify both fp_internal.h to list each driver
definition structure, and core.c to add those drivers to arrays we
can loop over, generate both of those using meson.
We shouldn't need to specifically enable debug logging to get useful
data out of a compiled libfprint either, so always enable debugging
output. It will still be switched off at runtime, by default.
There are no parts of libfprint that are so resource intensive that we'd
want to disable logging. This avoids (hopefully rare) cases where
compiled versions of libfprint are distributed with logging completely
disabled, and thus can't be debugged.

Add naive detection of image encryption: if stddev between two

and decrypt it.

Use fpi_mean_sq_diff_norm() for blank line detection and
fpi_mean_sq_diff_norm() for duplicate line detection.
Fixes finger presence and removal detection.
The code was indented, but only the first call was actually in the
conditional, which meant that initialisation carried on as normal on top
of a failed USB device. Exit early and remove the conditional to fix
this.

The device is already supported by the vfs5011 driver and non-
blacklisted, so will show up in the udev rules, but for ease of
backporting to older versions, add it to the whitelist anyway.

It seems that on faster devices, the driver can get more duplicate lines.
Without this change scan looks too stretched.
Suggested by: Thomas Rinsma <thomasrinsma@gmail.com>
Smart sensors like Upek TouchChip Coprocessor can provide scan status instead
of image, as result we need to report such status as "short scan" or "finger not centered"
from within the driver, since it's not a session error.
Sensor width seems to be only 128 pixels and that's not enough
for scanning whole finger surface. Lower bz3_threshold to 25,
since for wrong finger score never goes above 10, but sometimes
for right finger score is below 40.

Some scanners provide hardware assistance in frame assemling, i.e.
horizontal and vertical offset to previous frame is provided. This
commit improves code to utilise that assistance. Sensors without
hardware assistance will use software algorithm, which was also
improved to do search in horizontal direction.
pixman is very lightweight library for pixel manipulation, and it
has no dependencies except glibc, so using it instead of gdkpixbuf/imagemagick
makes list for libfprint dependencies a bit shorter.
Imaging drivers aren't allowed to change number of enroll stages anymore,
all that imaging driver does is providing image to the upper layer.
Upper layer decides if it needs more scans.

Since 5 scans for enroll was introduced it's not necessary to lower
bz3_threshold anymore, there's a good probability that scan to verify matches
with at least one enrolled sample.

The blacklisted devices weren't correctly checked for past the first
item, as we weren't using the right index to get the product ID
from the ID table.
Re-check device state after fpi_drvcb_enroll_stage_completed().
If enrollment was cancelled after non-completing stage, we must
not restart acquire as it would confuse the internal state machine.

Call error callback before resetting img_transfer to NULL. This
variable is internally used to detect if we are still in imaging
loop and the call to execute_state_change() needs to be postponed.
Since this is the final thing imaging_complete() we can't reset
img_transfer until just before this call.

Wait for 3 empty frames before stopping the scan
The driver used to stop the scan immediately after an empty frame
(by checking for hist sum == 0), but it is possible to get empty
frames in the middle of the scan due to low finger pressure.
Waiting for 3 empty frames stop the driver wrongly aborting the scan
too early.
