FUSE_INCLUDE_DIRS should be passed to the native_simulator build. If there is several fuse libraries installed, we need to ensure the bottom side of the driver is built with the correct include paths. (These includes are irrelevant for the Zephyr side build) Support having a list of include paths instead of single one. Support having a list of libraries to link to instead of a single one.

Avoid a possible race between the FUSE thread and the Zephyr threads during init. Signed-off-by: Alberto Escolar Piedras <alberto.escolar.piedras@nordicsemi.no>
Support using FUSE v3, instead of FUSE v2. FUSE v3 has been out for a couple of years now, so most distributions have it. But note the FUSE library (and its v3 branch) is currently unmaintained, and older distributions do not ship it. Some Linux distros have transitioned their packages away from fuse2. Which results in less atention in these distros to fuse2, and therefore a higher likelyhood that there would be distribution issues with the corresponding packages. There is also some likelihood the fuse2 packages may be eventually droped by some of these. So let's support either version, with a kconfig adapting to either API and their quirks. Note that both the fuse2 and fuse3 library code have quite a few sideeffects on the process that uses it. By now we continue defaulting to fuse2 as it is the most common. But users can select to use the v3 if they have an issue w v2 or want to start trying out using v3. Signed-off-by: Alberto Escolar Piedras <alberto.escolar.piedras@nordicsemi.no>

There was a problem hiding this comment.
I think it would be useful to add a sentence here to enable CONFIG_FUSE_LIBRARY_V3 if using fuse v3.
