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.

Factored out setup directory search path for source files into Makefile.include.
...
- All compilers used support the -I option for setting an include search directory.
- The Contiki source tree follows the (common) approach of placing declarations (in headerf iles) in the same directory as definitions (in source files).
As a result it makes sense to use the -I compiler option for just the same set of directories used for the vpath gnumake directive.
Note: I checked several builds but nevertheless one or the other might need some additional adjustsments. Sorry for the inconvenience.
