    Make btrfs_size_*() static member functions
    
    The member functions btrfs_size_to_num(), btrfs_size_max_delta() and
    btrfs_size_to_gdouble() don't access any member variables.  Therefore
    they don't need the const qualifier allowing them to be called when the
    btrfs object is const for read-only access to member variables, but
    instead need to be static member functions with no access to member
    variables.
