Use log crate instead of hand-rolled solution.

  * Remove my logging macros except *_now variants, since those are
    still handy.

  * Move log flush into RTC handler. This probably belongs in a
    separate timer at some point.

  * Change all old log messages to log crate's macros, except the
    Panic and HardFault calls.
