dt_imageio_open_tiff(): use TIFFGetFieldDefaulted to get TIFFTAG_SAMPLEFORMAT

Some applications(e.g. convert(1)) do not set it, and using TIFFGetFieldDefaulted ensures that it we get some value.
Apparently default is SAMPLEFORMAT_UINT.
If there is an app that does not set this field to SAMPLEFORMAT_IEEEFP when saving float data there, or otherwise, there might be problems...
Revert "Temperature iop: disable piece if preset == passthrough". Fixes #10108

opencl: fix beignet blendop warning

Beignet 0.9.2 built against LLVM 3.4 produces the following warning while compiling our OpenCL kernels:

[opencl_init] compiling program `blendop.cl' ..
[opencl_fopen_stat] could not open file `/home/pmjdebruijn/.cache/darktable/cached_kernels_for_IntelRHDGraphicsHaswellUltrabookGT2Mobile/blendop.cl.bin'!

OpenEXR: introduce compression controls
noise profiles for Fuji X-T1
Merge branch 'master' of ssh://github.com/darktable-org/darktable
Add legacy_params to libs & imageio ...

... and use it for exr
noise profile: olympus e-m10 by polarfox
tiff write_image: rewrite. Use memcpy. Do not overflow
Also set field TIFFTAG_ORIENTATION to ORIENTATION_TOPLEFT.

TIFFTAG_SAMPLESPERPIXEL was set earlier, no reason to set it again.
EXR write_image(): eliminate 3 temp buffers with total size of 3*width*height*sizeof(float)
This is also faster, while image's md5 is still the same (when exif is commented, compression is off and pixel type is float)
EXR: wording changes
EXR: threading

*MUCH* faster on computers with multiple processors.
With all recent changes, EXR export (PIZ, float) time is down from 13 sec to 3 sec for me.
Fix typo.
EXR: setting pixel type does not work, so let's not use it. Compression still works.
TIFF: ignore unsupported ICC profiles (Grayscale colorspace). fixes #10110
dt_mipmap_cache_static_dead_image: do not assume that sizeof(dt_mipmap_buffer_dsc) == 1
Credit for finding this goes to Pascal Obry. Thanks!

It is 2 now on 64-bit and 1 on 32 bit. Originally it was 1 always.
Why this code wasn't using sizeof() originally?
