dt_image_t & filter flipping deal w/x-trans raws

- storage for the x-trans 6x6 pattern in dt_image_t as well the Bayer
  pattern
- if dt_image_t.filters (the Bayer demosaic pattern) is 9, should use
  dt_image_t.xtrans (the X-Trans demosaic pattern) instead
- dt_image_flipped_filter() is a nop for X-Trans raw files, as the
  x-trans filter will be flipped on image load
fast downsampling to demosaic x-trans images
linear demosaic for x-trans files
highlights module for x-trans
temperature iop for x-trans
hotpixels for xtrans
raw denoise for x-trans

Use per-channel nearest-neighbor interpolation rather than downsizing
the channel.
invert module for x-trans

Also flip roi_in x/y for some bayer cases and don't divide by
0xffff in bayer float case (typos?).

- white balance presets for x100s
- measured fujifilm x100s basecurve
more demosaic tuning for x-trans

- for x-trans don't downsample if scale > 33.3%
- don't use Bayer-only edge-aware median for < 1/3 scaled exports
- hide Bayer-only options in GUI
- use OpenMP for bilinear demosaic
- disable green-matching in demosaic for x-trans
- s/xtrans_lin_interpolate_f/xtrans_lin_interpolate/
- use a bitmask to show difference between Bayer and xtrans
  dt_iop_demosaic_method_t's
- default to X-Trans or Bayer demosaicer depending on image type

Regarding the first change: for Bayer don't downsample if scale > 50%.
For x-trans, the fast down-sample works off of 3x3 sensor matrix (which
is 1/4 of whole sensor pattern), rather than 2x2 as with Bayer.
first pass at Markesteijn demosaic for x-trans

Not ready for use! For now this is pretty much the dcraw code wrapped
to work w/in demosaic module. The demosaic pipeline data is converted
to dcraw-friendly format for processing, then converted back
post-processing. The dcraw code is 16-bit integer, rather than
floating point. Provisional and slow, but still noticeably better than
bilinear. Many other pieces need clean-up (c.f. the RGB to LAB
conversion).
