Ralph Little 41866df6e1 genesys: fix for computation of total file size exceeding unsigned 
Large scans that exceed 32-bits need cast to allow 64-bit size.

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 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

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.
