capturing; if we succeed, display the packet drops count as the "Drops" value in the status line and as the "Dropped packets" statistics in the summary dialog box, otherwise don't display it at all. In Tethereal, attempt to get the packet statistics from libpcap when capturing; if we succeed, and if there were any dropped packets, print out the count of dropped packets when the capture finishes. svn path=/trunk/; revision=3016
