Ithaca deprecation

type:deprecated

deprecation of --protocol ithaca (jakarta is now adopted)

also "compressed" the stdlib a bit by:

• curry/uncurry: having one version for function of 1 or less arguments
• having PROTOCOL_N PROTOCOL_N+1 not replicated :) (not visible for now, but any changed/new tezos function should now add only ~one line to stdlib
• stub failwith in module Test now always fails with unit (avoid generating dummy poly_thing)
