Linux/FUSE: honor inodes and map unknown errors to EIO

Browse Source 
Enable use_ino for Linux FUSE mounts so stable inode numbers returned by getattr and readdir are reported to userspace. For FUSE3, set fuse_config.use_ino from init; for FUSE2, pass -o use_ino because there is no fuse_config init hook.

Also map otherwise unhandled FUSE exceptions to EIO instead of EINTR, since these failures are not signal interruptions and should not encourage retry loops.
