Introduce CLOCK_BOOTTIME

This patch set (applies against tip/timers/core) extends the hrtimer, timekeeping, and posix-timer code to support a new
clockid: CLOCK_BOOTTIME.

CLOCK_BOOTTIME is identical to CLOCK_MONOTONIC, except it also includes any time spent in suspend (as currently measured by read_persistent_clock()). This allows applications to get a suspend aware monotonic clock.

Thomas, I've included your suggestions from the last round. Does this look like something you could queue for 2.6.39?

thanks
