Summary:
Switches from opam 1 to opam 2.
Opam2 has some cool new features that simplify some of the scripting.
Notable changes:
1. Use the new `opam lock` *plugin* from https://github.com/AltGr/opam-lock/ instead of https://github.com/rgrinberg/opam-lock. This has a simpler interface for our purposes.
2. Change the way `./build-infer.sh` can be called to use an already existing switch: simply pass `--user-opam-switch` to the script and it won't attempt to create/set the current switch. This can be used to build infer in a local switch for instance.
3. Take advantage of automatic pinning where possible, eg to install infer deps without using opam.locked.

Summary:
With flambda (`-O3`), compilation time is ~5x slower, but the backend is ~25% faster!
To mitigate the atrocious compilation times, introduce a new `opt` build mode in the jbuilder files.
- build in "opt" mode by default from the toplevel (so that install scripts and external users get the fastest infer by default), in "default" mode by default from infer/src (since the latter is only called directly by infer devs, for faster builds)
- `make byte` is as fast as before in any mode
- `make test` will build "opt" by default, which is very slow. Solution for testing (or building the models) locally: `make BUILD_MODE=default test`.
- You can even change the default locally with `export BUILD_MODE=default`.
The benchmarks are to be taken with a sizable pinch of salt because I ran them only once and other stuff could be running in the background. That said, the perf win is consistent across all projects, with 15-20% win in wallclock time and around 25% win in total CPU time, ~9% win in sys time, and ~25% fewer minor allocations, and ~5-10% fewer overall allocations. This is only for the backend; the capture is by and large unaffected (either the same or a tad faster within noise range).
Here are the results running on OpenSSL 1.0.2d on osx (12 cores, 32G RAM)

Exactly the same as base.

infer binary: 56870376 bytes (2.17x bigger)

capture is the same as base:

=== flambda `-O2`
Not nearly as exciting as `-O3`, but the compilation cost is still quite high:

Summary:
Installing with `opam pin` risks upgrading a lot of package in the current
switch, which is very slow. It's also wasted work since we'll install back
their older versions afterwards with `opam lock`. Moreover, that second step
can now fail if javalib needs to be recompiled (which it seems it does),
because we delete the javalib sources after having pinned them.
Solution: 1. do not install javalib at `opam pin` time, and 2. do not remove its source tree after pinning.

- change build-infer.sh so that it also tries to init opam even if a switch is
specified. This shouldn't matter according to my testing and that means that
it's easier to have `./build-infer.sh --opam-switch 4.04.0` work out of the box
without needing to initialise the `4.04.0` opam switch ourselves beforehand.
- use that in .travis.yml

- `make -C infer/src clang java` followed by `make -C infer/src clang` results
in a cached build the second time. Previously, a bug in ocamlbuild meant that
building infer/java would stomp over some files used by infer/clang, hence
infer/clang would get partially recompiled. More generally, alternating
between targets, or simply repeatedly calling `make` would result in unecessary

The instructions to install opam from the web on linux were not enough:
you need to install opam somewhere on the PATH. Moreover, the wget
command could erase "opam" if launched from the infer repo, which
already has an "opam" file.
./build-infer.sh's "opam init" command would fail if ocaml was not already
installed, instead of installing a default compiler.
Finally, check that ocamlfind is installed using the same logic as other
ocamlfind packages, to get an error message explaining how to get it
using opam if it's not installed, instead of just a failure.
