d: remove support for parse.error verbose

[adelavais]

Without the history, D should not support this option. Before the removal, 'detailed' and 'verbose' options generated the same code.

• data/skeletons/lalr1.d: Here.
• doc/bison.texi: Adapt tests to use 'detailed' instead of 'verbose'.
• tests/calc.at: Document it.

The patch was installed, I'm closing the PR.
