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.

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.
