	Some String++ refactoring, setting out in the general direction of
	eventually just using the STL std::string, not our own class.

	* String++.cc (String::cstr, String::cstr () const): Remove.
	(new_cstr_char_array): New function.
	* String++.h: Sync with above.
	Remove irrelevant "class io_stream;" declaration.

	* cygpackage.h: Add "class io_stream;" declaration, now no longer
	being supplied by side-effect.

	* filemanip.cc: Remove unneeded includes, add "using namespace std;".
	(parse_filename): Exchange some awkward pointer manipulation for
	std::string usage. Use new_cstr_char_array ().
	* filemanip.h: Sync with above.
	(fileparse): Improve style of declaration.

	* io_stream_cygfile.cc (io_stream_cygfile::normalise):
	Use new_cstr_char_array ().
	* site.cc (site_list_type::init, get_site_list): Ditto.
