Added support for 32-bit clock ticks: when reading the 32-bit value, make sure that it does not change between readouts to avoid reading right in the middle of it being updated

Removed safeguards around the update code for the timer; turns out they weren't needed (but instead triggered a bug in MSPsim)

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.
