Split the callout return value into two bits indicating either cancelled or draining/servicing state. This gets us a total of four callout states instead of three. This also will allow better diagnosis and debugging of callout related problems. Identify all callout clients in the kernel and make them use the correct CALLOUT_RET_XXX return value and test. Update the timeout(9) manual page to reflect these changes. END
