Split the fuse FS driver into 2 parts: A top built in the embedded side, with the embedded libC, and a bottom built in the runner side with the host libC. The error returns are converted to match the host libC. Also, before the host FUSE thread, which is asynchronous to Zephyr was calling directly into the Zephyr filesystem code, which resulted quite often if catastrophic failures or corruption of the Zephyr state. This is now fixed by having the FUSE thread queue requests to a Zephyr thread, which will be handled in the embedded side in a coherent way. This adds a slightly noticeable overhead, but the performance is still acceptable. Signed-off-by: Alberto Escolar Piedras <alberto.escolar.piedras@nordicsemi.no>

Link in the underlying file system libraries. This can be

enabled without CONFIG_FILE_SYSTEM to enable applications
|
|
to work directly with the underlying file system libraries.

This can be useful to avoid linking in the entire filesystem

implementation via `struct fs_file_system_t` if only a subset
|

is used.

Specify the maximum file name allowed across all enabled file

file name length for enabled in-tree file systems. This

supported by a file system may result in memory access

violations.
