bde fc1f58e6bb Always wake up writers after clearing TS_BUSY. This will soon be
essential when I fix excessive wakeups for output-below-low-water.
In cy.c and sio.c, wake up via the driver start routine to also
eliminate duplicated code involving the clearing of TS_TTSTOP.

Always (except in code to be replaced soon) call driver start
routine directly instead of going through ttstart().
