Config memory is reset to 0xff and initialized with 'factory defaults' if
a valid header & checksum is not found. Config version number is only
increased when information is _relocated_ or space is _reused_ so that old
versions can read and modify configuration changed by new versions.
Memory locations not used by a given version should not be
modified unless the header & checksum test fails.
