Support cabal update --index-state.
The strategy is to save an 01-index.timestamp file that remembers what --index-state the user requested during cabal update. Subsequently, we use that index state if no more precise index state was specified (via the flag or a project config.) Signed-off-by: Edward Z. Yang <firstname.lastname@example.org>
