pureboot 4: the loader carries its fixes' identity

Browse Source 
The unaligned-W and U2X-hand-over fixes change the loader's observable
on-wire behavior, and the --stay reconnect fix changes the host tool, so
both move: loader version 3 -> 4, tool VERSION 2 -> 3. The protocol and info
block are unchanged, so OLDEST_LOADER stays 1.
