Add Yacc library, since POSIX requires it.
* doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
* lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
* lib/main.c, lib/yyerror.c: New files.
gram_error can be static; it need not be extern.
* src/reader.h (gram_error): Remove decl.
* src/parse-gram.y (gram_error): Now static. Add static decl.
(print_token_value): Omit parameter names from forward decl,
for consistency.

* doc/bison.texinfo: Emphasize that yylex and yyerror must
be declared before being used. E.g., one should typically
declare them in the prologue. Use GNU coding style in examples.
Put "const" consistently after the type it modifies. Mention
that C99 supports "inline". Mention that yyerror traditionally
returns "int".
%parse-param and %lex-param now take just one argument, the
declaration; the argument name is deduced from the declaration.
