Put pcap_win32_err_to_str() into fmtutils.c, and use it for all Win32 errors.

We don't need N different places all doing their own calls to
FormatMessage(); centralize it in pcap_win32_err_to_str(), now in
fmtutils.c for use in rpcapd as well as libpcap.

Merge in some fixes from the code in sock_fmterror().
