first step in adding sheetfed scanners calibration

- initial calibration process for sheetfed scanners upto strip finding
- create a scanner calibration function that switches between
flatbed or sheetfed calibration
- added a sheetfed calibration function
- removed gamma table setting from calibration process
- call gamma setting during sane_start but before scanner calibration

standardize including local sane/ include files.

Source code was inconsistent on how they were referencing
include files in include/sane. In certain cases, sane/sane.h
and sane/saneopts.h was really including external copies (with
some preprocessor implementations anyways).
