Use Path type for mount points
Implemented sendable trait for file locks and tuples of sendables
Implemented dispatching of create, getlk and setlk operations
Added dummy dispatching for interrupt operations (still does nothing)
Made opcode match expression exhaustive
Convert to fuse_opcode enum using the FromPrimitive trait rather than doing an unsafe transmute
Don't debug print unused mode for open and opendir operations. Output octal mode for create operation
Some doc updates
Fix logging after mozilla/rust#10006
