Simplified the statistics code. Don't crash if the time moves

backwards, but log a nice error message including how much the time
moved.

+	Simplified the statistics code.  Don't crash if the time moves
+	backwards, but log a nice error message including how much the
+	time moved.
+	* src/server/connections.c (set_time): Log how much the time moves
+	backwards when it moves backwards.
+	* src/server/stats.h (check_all_stats): Removed. 
+	* src/server/stats.c: Don't attempt to keep a running average.
+	Rounding errors are far too common.  Recompute it whenever it is
+	requested instead.  This results in simpler code as well.
+	(dump_stats): Removed.
+	(update_one_stat): Check if the time moves backward, to avoid
+	triggering an assertion.
+	(is_nonzero): Removed.
+	(check_all_stats): Removed.
+	* src/server/ramkomd.c (main): Removed calls to check_all_stats().
+
 	Simplify handling of the sent_by misc-info.  Allow the supervisor
 	of the author and sender to modify or remove a recipient (Bug 966,
 	Bug 181 and Bug 1089).  Don't allow a text to be both a footnote
