Bison语法分析器

	(get_type_name, copy_guard, copy_action, readgram)
	(get_type, packsymbols):  Revised most error messages.
	Changed `fatal' to `warnxxx' to avoid aborting for error.
	Revised and use multiple warnxxx functions to avoid using VARARGS1.
	(read_declarations): Improve the error message for
	an invalid character.  Do not abort.
	(read_declarations, copy_guard, copy_action): Use
	printable_version to avoid unprintable characters in printed output.
	(parse_expect_decl): Error if argument to %expect exceeds 10 digits.
	(parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
	Allow the type of a non-terminal can be given
	more than once, as long as all specifications give the same type.

	* output.c: (output_headers, output_trailers, output, output_gram)
	(output_rule_data): Implement noparserflag variable.
	Implement toknumflag variable.
	(output): Call reader_output_yylsp to output LTYPESTR.

	* main.c (main):  If reader sees an error, don't process the grammar.
	(fatals): Updated to not use VARARGS1.
	(printable_version, int_to_string, warn, warni, warns, warnss)
	(warnsss): New error reporting functions.  Avoid abort for error.

	* lex.h: Added THONG and NOOP for alias processing.
	Added SETOPT for the new code that allows setting options with %flags.

	(lex): Use literalchar.
	(lex): Implemented "..." tokens.
	(literalchar, lex, parse_percent_token): Made tokenbuffer
	always contain the token.  This includes growing the token
	buffer while reading an integer.
	(parse_percent_token): Replaced if-else statement with percent_table.
	(parse_percent_token): Added % declarations as another
	way to specify the flags -n, -l, and -r.  Also added hooks for
	-d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
	major changes to files.c.
	(lex) Retain in the incoming stream a character following
	an incorrect '/'.
	(skip_white_space, lex):  Revised most error messages
	and changed fatal to warn to avoid aborting.
	(percent_table):  Added %thong declarations.
