    extmod: Add generic VFS sub-system. · dcb9ea72
    Damien George authored
    This provides mp_vfs_XXX functions (eg mount, open, listdir) which are
    agnostic to the underlying filesystem type, and just require an object with
    the relevant filesystem-like methods (eg .mount, .open, .listidr) which can
    then be mounted.
    
    These mp_vfs_XXX functions would typically be used by a port to implement
    the "uos" module, and mp_vfs_open would be the builtin open function.
    
    This feature is controlled by MICROPY_VFS, disabled by default.
