- Client (Win): in file_size(), use _stat64() instead of stat().

Otherwise it doesn't work for files >= 2GB
	- Client: TIME_STATS::trim_stats_log() wasn't working because
		it's called in the constructor of TIME_STATS,
		which is called before we've done a chdir() to the data dir.

	Note: for this reason, no disk access should be done in constructors
	of global objects.  A quick scan found no instances of this.
