Leander Kohler 51bd9d24f3 vmm, vm-migration: validate protocol version at start ...

Validate the sender's migration protocol version when
handling the initial Start request.

Read the version from the Start command header, accept only
the supported version window n-1..=n, and reject unsupported
versions with Error. A rejected Start moves the receiver to
the aborted state.

This keeps compatibility one-way, from older protocol
versions to newer ones, and leaves later version-based
branching on the receiver side.

Log the protocol version on both sender and receiver to make
the active migration path visible.
