This is the first attempt at moving all internal parts from using struct timeval to integer ticks. Those provides simpler and faster code due to simplified operations, and this change also saved about 64 bytes per session. A new header file has been added : include/common/ticks.h. It is possible that some functions should finally not be inlined because they're used quite a lot (eg: tick_first, tick_add_ifset and tick_is_expired). More measurements are required in order to decide whether this is interesting or not. Some function and variable names are still subject to change for a better overall logics.
