Guy Harris 7ddca7ecaf From Lars Roland: 
Add Response-Time statistics for each known mgcp message-type.

	Fix a few bugs and remove trailing whitespace.

	Use "gdouble" for printing time-values and calculating the
	average.  It is easier to use and shouldn't overflow on big
	trace files like "guint32".

	Move some functions for time statistics into the new file
	timestats.c in the main directory.  This code may be useful in
	the rpc and smb rtt-taps as well.
