Build text2pcap on Windows.

Fix text2pcap.c so that it can be compiled with Microsoft Visual C++
6.0:

	protect some includes with #ifdefs, as not all the header files
	in question exist in the MSVC++ build environment;

	include <winsock.h> if we have it, to declare "ntohs()" and the
	like;

	include "getopt.h" if we need it, to declare stuff for
	"getopt()";

	include "config.h" if we have it, so we know whether the header
	files in question exist or are needed;

	rename "BYTE" to "READ_BYTE", as <winsock.h> defines BYTE as
	well, and that definition causes a conflict;

	get rid of references to "__FUNCTION__", as MSVC++ doesn't
	define it (I suspect at least some UNIX compilers don't define
	it, either).
