Ondrej Zary 464dfeb5c6 rts8891: gamma-correct image in find_origin and find_margin 
Apply gamma correction to image in find_origin and find_margin
to allow correct detection with cold lamp.
Also find 4 consecutive white pixels (instead of one) in find_margin.

Ondrej Zary eff6358dd7 rts8891: fix 100dpi 
Make 100dpi scanning (and preview) really work.
Register 0x7a is x-divider, setting it to 2 divides the 200dpi horizontal
resolution to 100dpi.
So the amount of data is halved but the scanning area and shading data must
be set as when scanning at 200dpi.

David Ward f3162bafa8 Replace variable self-assignments to avoid Clang warnings 
These were intended to suppress GCC warnings about unused variables.
However, this leads to different warnings from Clang instead.

Use another approach that suppresses warnings from both compilers.

David Ward 4cf3b09e49 rts8822, rts8891: Replace abs() with fabs() where needed 
abs() has an integer parameter and returns an integer value. Floating-
point values should be passed to fabs() instead.

In particular, this affected calculations for gain and offset, where a
value with floating-point precision is clearly expected.

Wolfram Sang eb42ad08d5 treewide: use SANE_CURRENT_* macros consistently 
Backends use a mixture of SANE_CURRENT_{MAJOR | MINOR} and V_{MAJOR |
MINOR} with all kind of permutations. I was confused by this and one
comment in pieusb.c tells me I was not alone. Some items in old
changelogs suggest to use the SANE_CURRENT_ macros in backends, so let's
switch to do that with the exception of net.c and dll.c. Done with:

$ find backend -name '*.[ch]' | xargs sed -i '/nearly every/ ! { s/\<V_M/SANE_CURRENT_M/g }'
$ git checkout backend/net.c backend/dll.c

And manually removing the comment from pieusb.c. Everything still builds
fine.

pobrn 45f84a569c respect 'local_only' parameter of sane_get_devices() 
Certain backends do network scans even if the 'local_only'
parameter for 'sane_get_devices()' is true. Fix that.

Changes:

1. Modify 'sanei_configure_attach()' so that backend specific
   data may be passed to the 'attach()' function.

2. Use this in certain backends to pass the value of the
   'local_only' parameter so that network related activities
   are only carried out when the value is false.

to cast away the 'const' qualifier when releasing these resources.
