	* libcsupport/include/rtems/libio_.h: Declare
	rtems_filesystem_mount_table_control.
	* libcsupport/include/rtems/libio.h: Removed
	rtems_filesystem_table_first(), rtems_filesystem_table_next() and
	rtems_filesystem_table_node_t declarations.  Declare
	rtems_per_filesystem_routine, rtems_filesystem_iterate() and
	rtems_filesystem_get_mount_handler().
	* libcsupport/src/mount.c: Added rtems_filesystem_mounts_first() and
	rtems_filesystem_mounts_next().  Simplify mount().  Removed
	rtems_filesystem_mount_table_control_init.  Use
	rtems_filesystem_get_mount_handler().
	* libcsupport/src/mount-mgr.c: Removed rtems_filesystem_mounts_first() and
	rtems_filesystem_mounts_next().  Added rtems_filesystem_iterate() and
	rtems_filesystem_get_mount_handler().  Use rtems_libio_lock() and
	rtems_libio_unlock();
	* sapi/include/confdefs.h, libmisc/shell/main_mount.c: Update for
	mount API changes.
