d: add support for lookahead correction
When using lookahead correction, the method YYParser.Context.getExpectedTokens
is not annotated with const, because the method calls yylacCheck, which is not
const. Also, because of yylacStack and yylacEstablished, yylacCheck needs to
be called from the context of the parser class, which is sent as parameter to
the Context's constructor.
* data/skeletons/lalr1.d (yylacCheck, yylacEstablish, yylacDiscard,
yylacStack, yylacEstablished): New.
(Context): Use it.
* doc/bison.texi: Document it.
* tests/calc.at: Check it.
