7dfe24ee2c Rework kboot/chainload flow to shut down before calling the next stage 
Next stage boots now exit back to main() after replying to the proxy
command, allowing shutdown functions to be called. Introduces a new
P_VECTOR proxy op, distinct from P_CALL. The Python side is reworked
to remain compatible with older versions that do not support this.
