Jeff Morriss a5cee04fad Move the file utility functions from wiretap to libwsutil so that
libwireshark (and the plugins using those functions) do not depend on
wiretap on Windows.

While doing that, rename the eth_* functions to ws_*.

Some thoughts about a GTK win32 printer dialog:
"EnumPrinters()", asking for information level 2 - the PRINTER_INFO_2
structure contains a pLocation string pointer, along with other
information.
"PrinterProperties", could be used to show a native printer property page?!?
See
