Summary:
This seems like a bug in opam, probably started after we moved the opam
files to opam/ in D27326495 (673c944fc3). I reported the strange behaviour in
https://github.com/ocaml/opam/issues/4313#issuecomment-853179145.

Summary:
This diff renames and moves the opam package definition files to
`<package>.opam` in an `opam` directory at the root of the
repository. This enables opam pinning the different packages contained
in the repo. It is necessary for these files to be either at the root
of the repo or in a directory named `opam` at the root of the repo, or
else opam cannot find them.

Summary:
Before: 3 modes: (where "lenient" build has warnings not crash the
build, while "strict" build errors on warning):
- opt (default): flambda optimisations + lenient build
- dev (recommand for dev): lenient build, no flambda
- test: strict build (used in tests), no flambda
Now:
- dev (default): *strict* build, no flambda
- opt: lenient build, flambda
- dev-noerror: lenient build, no flambda (use when you want to test
infer but there are build warnings)
The goal is to give faster feedback to infer developers and reduce the
amount of times diffs are sent with build warnings. Also it's now faster
to alternate between changing infer and running unit tests since test
mode is just dev mode.

the error was also silently ignored).

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)

=== flambda with stock options (no `-Oclassic`, just the same flags as base)
Exactly the same as base.
=== flambda `-O3`
infer binary: 56870376 bytes (2.17x bigger)
compile time: 191s (4.78x slower)
capture is the same as base:
```lang=text

=== flambda `-O2`
Not nearly as exciting as `-O3`, but the compilation cost is still quite high:
infer: 37826856 bytes
compilation of infer: 100s
Capture and analysis timings are mostly the same as base.

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.

Let's try this one more time.
- 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
