Grégoire Henry b6449cae87 Jbuilder: split src/utils/ in multiple OPAM packages
* `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`)
