Summary:
## Issue
There are a number of times when users building `facebook-clang-plugins` hit memory limitations, typically due to the OOM killer and when linking.
In https://github.com/facebook/facebook-clang-plugins/pull/21, I implemented support for building `facebook-clang-plugins` using both Ninja and to only use one process when linking.
## Resolution
This PR exposes the optional flags added in https://github.com/facebook/facebook-clang-plugins/pull/21 to `build-infer.sh`, such that you can build `facebook-clang-plugins` with either just `ninja` or `ninja` + only one process for linking.
As part of this, it updates the `facebook-clang-plugins` submodule.

- make most behaviours independent of the java version so that either works fine without user intervention
- modify regexp used to parse `javac` output to work for all versions
- no need to be sure we are in Java 11 to match java 11-only method name in quandary
- for the rest, provide a command-line flag to specify the java version manually in case it differs from the version that infer was built against
- this only affects the Maven integration for now
To do all that, also change the configure script to record the version of java instead of just a boolean for whether it's >= 10.

Summary:
TL;DR: Until this patch, if you ran infer on MacOS Mojave you most
likely would get an error related to missing header files. Now infer
tries to automatically locate current MacOS SDK path thus providing a
better experience for first time users.
Consider helloworld.c
```
#include <stdio.h>
int main()
{
return 0;
}
```
Invoking the analysis `infer -- cc -c helloworld.c` fails with
facebook-clang-plugins/.../include/c++/v1/stdio.h:108:15: fatal error: 'stdio.h' file not found
The reason for this is twofold:
1. infer uses its own clang, not Apple's one (thus custom paths are
not properly setup).
2. Apple stopped copying standard headers from SDK to /usr/include.

Previously it was required to provide SDKROOT during configure on Mojave

Use these and opam to copy the more exotic library objects into the installation of infer on a new `make install-with-libs` target so that the binaries can be distributed usefully, i.e., without users having to install gmp, mpfr, and more importantly apron and elina (which need ocaml + opam + ..., which would defeat the point of having binaries).

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.

It adds relational domains to Inferbo: octagon of Apron and polyhedra of Elina.
- Each Mem domain value includes one relational value containing relations among symbols. The relational values are modified by the `Prune` and `Store` commands.
- Each abstract value includes three symbols, which represent integer value, array offset, and array size of an abstract value.
The relational domain is deactivated by default. Use the `--bo-relational-domain {oct, poly}` option for the activation, though Inferbo with the relational domains does not work at this point because some modifications of Apron and Elina we made has not been applied to their opam repositories yet.

Run with `SHELL = bash -e -u -o pipefail` to catch many kinds of failures. We
were silently failing during `make install` because of some missing escaping,
and the failure was hidden because it was happening inside a bash `for` loop.
This fixes the escaping issue and makes sure such issues will result in an
error as of now.
Also removes dangerous `find -exec` instances: `find` will `exit 0` event if
some commands failed.

Menu:
1. Write a jbuild file, autogenerated from jbuild.in because we need to fill in
some information at build-time (really, at configure time, but TODO), such as
whether or not clang is enabled.
2. Nuke lots of stuff from infer/src/Makefile that is now in the jbuild file
3. The jbuild file lives in infer/src/ so it can see all the sources. If we put it somewhere else, eg, infer/, then `jbuilder` scans too many files (all irrelevant) and takes 2.5s to start instead of .8s. Adding irrelevant directories to jbuild-ignore does not help.
4. jbuilder does not support subdirectories, so resort to listing all the
source files in the generated jbuild (only source directories need to be
manually listed in jbuild.in though). Still, the generated .merlin is wrong
and makes merlin find source files in _build, so manually tune it to get
good merlin support. We also lose some of merlin for unit tests as it
cannot see their build artefacts anymore.
5. checkCopyright gets its own jbuild because it's standalone. Also, remove
some deprecation warnings in checkCopyright due to the new version of Core from
a while ago.
6. Drop less-used Makefile features (they had regressed anyway) such as
building individual modules. Also, building mod_dep.pdf now takes all the
source files available so they better build (before, it would only take the
source files from the config, eg with or without clang) (that's pretty minor).
7. The toplevel is now built as a custom toplevel because that was easier. It
should soon be even easier: https://github.com/janestreet/jbuilder/issues/210
8. Move BUILTINS.mli to BUILTINS.ml because jbuilder is not happy about
interface files without implementations.
In particular, I did not try to migrate too much of the Makefile logic to jbuilder,
more can be done in the future.
