interpolation: OpenCL implementation of interpolation_resample

implementation with naive 1:1 copy of CPU code. as to be expected this is
slow as hell combined with a huge workload on the gpu

opencl, interpolation: a bit less naive implementation
Try to limit network traffic of map view

There is no reason to keep a connection to a map server when dt is not
in map view. This should be relevant for bug #9816.
opencl, interpolation: make better use of local memory

speed wise this should now be ahead of the CPU code
opencl, interpolation: small fix and some added comments
Removed check for ambiguous return values for lens lookups.

It can *never* be guaranteed that the return list of lenses of lensfun contains
only one entry, even if the lens model name was exactly correct.  Lenses with a
longer lens name (containing the shorter one) will also be returned.  However,
it is guaranteed that the exact match will be returned as the zeroth list
element.

Bug 9807: Correct Olympus Focus Distance

Originally the Focus Distance seems to be stored in a Rational (Fractional) format.

There seems to be some confusion about where the stored value is in centimeters versus millimeters.

This confusion seems to stem from the fact that some implementations seem to ignore the denominator of 10,
using the numerator directly (and incorrectly).

Exiv2's toFloat function properly divides the numerator by the denominator when outputting a Float (as centimeters).

So we need to divide by 100 to get meters.

Olympus seems to have strange focus distances

This hopefully fixes #9807 for real now.
Rewrite of tiff file reader.
Clarified codepaths based on tiff format to simplify future work of
implementation of seperate contif format.

This commit also includes a few crushed bugs and fixes #9821
