* `lib_stdlib`: basic extended OCaml stdlib and generic data structures * `lib_data_encoding`: almost independant 'Data_encoding' * `lib_error_monad`: almost independant 'Error_monad' * `lib_stdlib_lwt`: extended Lwt library * `lib_crypto`: all the crypto stuff (hashing, signing, cryptobox). * `lib_base`: - basic type definitions (Block_header, Operation, ...) - a module `TzPervasives` to bind them all and to be the single module opened everywhere. In the process, I splitted `Tezos_data` and `Hash` in multiple submodules, thus removing a lot of `-open`. The following two modules may not have found their place yet: - Base58 (currently in `lib_crypto`) - Cli_entries (currently in `lib_stdlib_lwt`)
