cpphash.h (struct cpp_reader): New members line, pseudo_newlines.

	* cpphash.h (struct cpp_reader): New members line, pseudo_newlines.
	* cpplex.c (handle_newline): Update prototype.  Maintain logical
	line number.
	(skip_escaped_newlines, skip_block_comment, parse_string):
	Update accordingly.
	(_cpp_lex_token): Update, and store token position within the token.
	* cpplib.h (struct cpp_token): Add line and column entries.
	* cppmacro.c (replace_args): Position stringified tokens correctly.
