Pass the struct fp_dev and user_data to fpi_ssm callbacks, so that we
might be able to get rid of the fpi_ssm_get_user_data(), and
fpi_ssm_get_dev() as most drivers just get those from the ssm anyway
in their callbacks.
Not precise enough, and it was only used in upekts to get/set the
instance private struct and keep it around, so add a new, more precisely
defined field to fp_dev for that.
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
Which avoids passing zero lines to fpi_assemble_lines()

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]

^~~~~~~~~~~~~~~~~~~~~~~
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.
