2162aa9f48 uru4k: decrypt image if necessary 
Add naive detection of image encryption: if stddev between two
adjacent rows is higher than threshold assume that image is encrypted
and decrypt it.

a1f36c71c9 upeksonly: decrease bz3_threshold for 147e:1001

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.

76269decdd aes4000: Fix possible crash if USB init fails 
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.

487dae0d2f Work-around kernel's lack of USB PM 
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.

6e8d5cd6a1 vfs5011: do duplicate line search for 30 lines 
It seems that on faster devices, the driver can get more duplicate lines.
Without this change scan looks too stretched.

a656a4a9f3 upektc_img: Handle scan status reported by sensor properly 
Sensor can report "short scan" or "finger not centered" instead of image,

2944a35e74 imgdev: Add fpi_imgdev_abort_scan() to abort scan gracefully from within the driver. 
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.

985e8c4577 aes1660: set partial flag on an image 
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.

9f408bf51b imgdev: fix enum mismatch for dev_change_state() call 
This bug has existed long time, but it was uncovered by commit
e215b05094 which enabled multiple enrollment rounds.

In practice this broke (at least) URU4000 driver state machine
causing it to enter indefinite loop - due to the invalid state
change callback.
