bug fix, msp430 hw bug (undocumented):
...
when in continuous/compare mode the interrupt handler may get called before CCR==TR.
behavior observed when the timer is toggled between STOP/CONT in an external interrupt handler (serial input).
possibly this problem may also affect watchdog timer/timer B

Added a clock_seconds() function prototype to core/sys/clock.h, that returns seconds in 32 bit format. On platforms like the MSP430, which has a 16 bit native datatype, this cannot be implemented with an interrupt tick that increments a 32 bit value because access is not atomic. Instead, the MSP430 code increments 16 bit seconds value and converts this into a 32 bit value through an offset calculation. If the new value is smaller than the last check, the offset is incremented by 65536. This change also means that CLOCK_CONF_SECOND must be a power of two because a modulo operation is used inside the periodic tick interrupt handler.
