d: change api.token.raw default value to true
...
Generate consecutive values for enum TokenKind, as D's yylex()
returns TokenKind and collisions can't happen.

* tests/scanner.at, tests/d.at: Check it.

d: change the return value of yylex from int to TokenKind
...
* data/skeletons/lalr1.d: Change the return value.

* tests/scanner.at: Adjust.
* tests/calc.at (_AT_DATA_CALC_Y(d)): New, extracted from...
(_AT_DATA_CALC_Y(c)): here.
The two grammars have been sufficiently different to be separated.
Still trying to be them together results in a maintenance burden. For
the same reason, instead of specifying the results for D and for the
rest, compute the expected results with D from the regular case.
