Improve halt behaviour (trickle clocks)

On halt, finish all four phases of the clock. Restarting from halt
appears to work now. Now halt needs to be deasserted (brought low) after
reset is deasserted (brought high) ; should this be required ?
Mend startup issues

Make reset and halt independent, and cause first instruction not to be
skipped.
Mend multiple-driver issue for clk0_seen
