We rename the generated lexer from yylex to glcpp_lex. Then we implement our own yylex function in glcpp-parse.y that calls glcpp_lex. This doesn't change the behavior at all yet, but gives us a place where we can do implement alternate lexing in the future. (We want this because instead of re-lexing from strings for macro expansion, we want to lex from pre-parsed token lists. We need this so that when we terminate recursion due to an already active macro expansion, we can ensure that that symbol never gets expanded again later.)
