istream.tcc (getline(char_type*, streamsize, char_type), [...]): Restore a generic version of the functions...

2004-11-08  Paolo Carlini  <pcarlini@suse.de>

	* include/bits/istream.tcc (getline(char_type*, streamsize,
	char_type), ignore(streamsize), ignore(streamsize, int_type)):
	Restore a generic version of the functions, not using the
	protected members of basic_streambuf.
	* include/std/std_istream.h (getline(char_type*, streamsize,
	char_type), ignore(streamsize), ignore(streamsize, int_type)):
	Declare optimized specializations for char and wchar_t.
	* src/istream.cc: New file, define the latter.
	* src/Makefile.am: Add.
	* src/Makefile.in: Regenerate.
