SMB RTT statistics for tethereal and ethereal.

SMB RTT statistics are similar to the RTT statistics already supported by ONC-RPC and DCE-RPC.
It will present a table with all seen SMB commands and present the Min/Max and Avg response time in ms.

Transaction2 and NT-Transaction commands are broken out and presented in its own subtables.

tethereal feature is activated with -z smb,rtt    switch
and in ethereal it is activated either through -0z smb,rtt switch or through the Menu.
