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
serves no purpose, and the function itself is deprecated.
Follow-up from commit 1f0079a274.
libfprint/drivers/upekts.c: In function ‘alloc_send_cmd_transfer’:
libfprint/drivers/upekts.c:161:2: warning: ‘strncpy’ output truncated before terminating nul copying 4 bytes from a string of the same length [-Wstringop-truncation]
strncpy(buf, "Ciao", 4);
^~~~~~~~~~~~~~~~~~~~~~~
Replace with memcpy() to only copy the 4 bytes we need.

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.

libusb_free_device_list() needs to be called on the list of USB devices
obtained through libusb_get_device_list() or the list and its elements
will be leaked.

Add naive detection of image encryption: if stddev between two
adjacent rows is higher than threshold assume that image is encrypted
and decrypt it.
Fixes fd.o bug 88945
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.

[vasilykh]:
- use g_get_real_time() instead of non-portable time()
- use g_free() instead of free()
- comment out "RECV(VFS5011_IN_ENDPOINT_CTRL2, 8)"
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.
