This patch makes the following configuration changes: - MICROPY_FSUSERMOUNT is disabled, removing old mounting infrastructure - MICROPY_VFS is enabled, giving new VFS sub-system - MICROPY_VFS_FAT is enabled, giving uos.VfsFat type - MICROPY_FATFS_OO is enabled, to use new ooFatFs lib, R0.12b User facing API should be almost unchanged. Most notable changes are removal of os.mkfs (use os.VfsFat.mkfs instead) and pyb.mount doesn't allow unmounting by passing None as the device.
