#10029: fix lens detection for Sony ILCE bodies
Merge branch 'master' of https://github.com/darktable-org/darktable
[l10n] Swedish update
New Nikon D800 basecure computed with dt-curve-tool.

This new basecurve looks far better in the dark tones and closer to
the corresponding jpeg used during the process.
Fix comment, add message to do the purge in the database.
basecurve: add measured 6d curve
Set min for cache_size to 100 MB

This is however not enforced in the code, it's just used for the
preferences dialog!
Histogram: replace dt_iop_roi_t with new dt_histogram_roi_t
Spots IOP: legacy_params(): adapt for latest mask changes
dt_masks_legacy_params(): refactor v1 -> v2 to a function, prepare for v3
Needed preparations for loading of uncropped, unscaled (B/W) raw images
dt_imageio_open_rawspeed(): break everything! Stop cropping.
Masks: bump version

Legacy masks update infrastructure will be updated later
rawprepare: new IOP, no-op (passthrough)
rawprepare: allow tiling

FIXME: verify this!

Mipmap cache: prepare for border cropping for (downsampled) floating point buffers
Mipmap cache: prepare for border cropping for (downsampled) floating point buffers [X-Trans]

FIXME: do actually flip filter acc. to rawprepare iop crop x,y
rawprepare: border cropping for floating point buffers
rawprepare: set IOP_TAG_DISTORT, implement distort_(,back}transform
