Add a "pcap_dump_ftell()" routine, to fetch the current offset of a

pcap_dumper_t.  (Just doing an "ftell()" on the result of
"pcap_dump_file()" won't necessarily work on Windows, as Microsoft, in
their infinite wisdom, have multiple different versions of the C library
runtime, and if a DLL is built using one version, and another DLL or an
executable is built with another version, file descriptors and FILE *'s
opened in one of them cannot be used in the other.)
