Improvments to time-measurement and stats: - move all the platform-dependent timing related stuff into posix/GetTime.c and win32/GetTime.c, with the machine-indepent interface specified in GetTime.h. This is now used by Stats.c. - On Unix, use gettimeofday() and getrusage() by default, falling back to time() if one of these isn't available. - try to implement thread-specfic CPU-time measurement using clock_gettime() on Unix. Doesn't work reliably on Linux, because the implemenation tries to use the processor TSC, which on an SMP machine goes wrong when the thread moves between CPUs. However, it's slightly less bogus that before, and hopefully will improve in the future.
