Povilas Kanapickas 59506f866d genesys: Remove exception for the GPL license 
Several files already don't have the exception that allows uses of the
code that are additional to the GPL license. I'm no longer comfortable
granting this exception for my subsequent contributions, thus the
exception has been removed.

Povilas Kanapickas d19ccd2fad genesys: Remove no longer used led calibration fallback code on gl841 
This was used only on scanners which did not have calibration target

can be removed.

Povilas Kanapickas 675497fcd8 genesys: Use host-side gray instead of device-side true-gray on gl841 
True gray mode is not handled correctly by devices: they have bugs that
lead to incorrect LED color being emitted (e.g. dark red) and thus this
feature is completely unusable. At least LiDE 35/40/50, LiDE 60 and LiDE
80 are affected.

Simpy disabling true-gray unfortunately leads to even worse outcome
because the scanner then simply proceeds to perform a color scan.

To work around these problems we do a normal color scan and then produce
gray output based on the color data. This will satisfy the use cases
when correct gray is needed. In cases when it is sufficient to construct
gray from a single color channel, the color filter setting could be
used.

Povilas Kanapickas 1e75025048 genesys: Fix incorrect scan exposure setup on gl841 
When sensor exposure values are significantly different from each other
the total scan exposure will be too low leading to the device becoming
confused and significantly

Povilas Kanapickas 6c0fafac79 genesys: Remove broken two-table feeding support from gl841 
At least on LiDE 50 two-table feeding caused unexplained motor spin-up
failures on certain motor exposures. Various register modifications
showed that there's high likelihood on device-side bug. Even the
official drivers don't use proper two-table feeding.

Povilas Kanapickas b668e92047 genesys: Use {uint,int}{8,16,32,64} from std namespace 
This is not strictly necessary as all known C++ compilers also inject
these types to the global namespace. However this is not guaranteed by
the C++ standard and accordingly some code completion tools don't
support this without additional configuration.

Povilas Kanapickas 80f6d21170 genesys: Enable gamma setting when contrast or brightness is adjusted 
Brightness and contrast adjustments are handled via gamma tables and
thus gamma functionality is required for these settings to have any
effect.

Previously if the device has a sensor with identity gamma
(gamma = {1, 1, 1}), then gamma tables were turned off, consequently
brightness and contrast settings had no effect.

The underlying issue was identified by Gunnar Hjalmarsson
<gunnarhj@ubuntu.com> and STK.
