The invariant of the `clear` function was not properly inforced by the
module interface. This patch remove the inappropriate invariant and
properly rename the function.
New category:
- node.distributed_db.p2p_reader
log all incoming message, from any peer (debug)
- node.distributed_db.scheduler.*
log the request scheduler of the given ressources (notice/debug),
where '*' might be:
- Operation_hash (individual operation)
- Block_hash (block header)
- operation_hashes (aggregated operation_hashes of a block)
- operations (aggregated operations of a block)
- Protocol_hash (protocol)
Concurent request of the same ressource might insert multiple 'Pending
request' in the request tracking table. Resulting, only one of them
will ever be satisfied and some worker might be stuck for ever. We
avoid this be removing any cooperation between lookup and insertion in
the table.
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.

Ouch! That was a subtle Lwt misuse.
With the current (very-old) validator code, when the validation of
block is waiting to the validation of its predecessor, a "pending" Lwt
thread is created. The validation of the predecessor might also wait
on its own predecessor, potentially creating a very long chain of
pending validation"... If in the process one of the block is tagged
invalid, all the pending "successors" in the chain are 'wakeuped'
immediatly and in sequence, potentially blowing the stack in the
process.
A quick fix is to add an `Lwt_unix.yield` to break the recursion.
A better fix is to not create such long chain of "pending" validations.

With this patch the economic protocol is now compiled as as
"functor-pack", parameterized over the environment. This will ease the
protocol reusability outside of the tezos source tree (e.g. for a
michelson Web IDE) and will allow proper unit testing of the economic
protocol.
This functorization allows to break the dependency of the
'tezos-protocol-compiler' on various '.mli' of the node, and hence
we don't need anymore the unusual compilation schema:
a.mli -> b.mli -> b.ml -> a.ml
where 'A' is linked after 'B' but 'a.mli' should still be compiled
before 'b.mli'. This will simplify a switch to 'ocp-build' or 'jbuiler'.
