Move utility routines for capturing into a libcaputils static library.
Some of those routines are used only in dumpcap; others are used in TShark and Wireshark as well. Change-Id: I9d92483f2fcff57a7d8b6bf6bdf2870505d19fb7 Reviewed-on: https://code.wireshark.org/review/2841 Reviewed-by: Guy Harris <guy@alum.mit.edu>
