Add ICMP tap support, and add a tshark tap to measure such things as:

  * Number of ICMP echo requests, replies, lost replies and percent loss.
  * Min, Max, Average SRT (Service Response Time), and standard deviation.
(This is my first tap, so hopefully I didn't miss something, but we'll see ...)

+Compute total ICMP echo requests, replies, loss, and percent loss, as well as
+min, max and average SRT statistics typical of ping statistics.

+Example: S<B<-z icmp,srt,ip.src==1.2.3.4>> will collect ICMP SRT statistics

+This option can be used multiple times on the command line.
