This is the first step towards a generated lexer as described in #6256. It adds methods to the parser struct, that make it implement the yyLexer interface required by a yacc generated parser, as described here: https://godoc.org/golang.org/x/tools/cmd/goyacc . The yyLexer interface is implemented by the parser struct instead of the lexer struct for the following reasons: * Both parsers have a lookahead that the lexer does not know about. This solution makes it possible to synchronize these lookaheads when switching parsers. * The routines to handle parser errors are not accessible to the lexer.
