This is a rewrite of the build system with `jbuilder`, with just a
minimal toplevel Makefile for backward compatibility.
This first patch preserves the project architecture, we only gain
proper dependencies handling and always up-to-date `.merlin` files.
A latter patch may split the project in smaller "sub-package",
i.e. multiple `.opam` files.
The embedded versions of the economic protocol are now compiled with
`jbuilder` instead of `tezos-protocol-compiler`, potentially allowing
proper inlining at the cost of slightly-less-stricter
sandboxing. Nevertheless, dynamically loaded protocol are still
compiled with the `tezos-protocol-compiler` and thus strictly
sandboxed ; and a CI rule also checks the proper sandboxing of
embedded protocols.

- introduced `test/utils/test_lib.inc.sh` to simplify usage of
sandboxed node/client in the testsuite
- it reuses code from `./script/{node,client}_lib.inc.sh`
- use `wait_for_the_node_to_be_ready` to properly wait for the node to
be launched rather to use a fexed delay
- `test_multinode.sh` now launch 8 nodes.
