Summary:
Use jbuilder to build infer instead of ocamlbuild. This is mainly to get faster builds:

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.

Summary:
Conversion and reformat of infer source using ocamlformat
auto-formatting tool.
Current status:
- Because Reason does not handle docstrings, the output of the
conversion is not 'Warning 50'-clean, meaning that there are
docstrings with ambiguous placement. I'll need to manually fix
them just before landing.

Summary:
This removes the dependency of libffi, and gives better guarantees at
compile-time. A bit overkill to retrieve the width of the terminal but what do
you know...

Summary:
This makes sure that one can run `./build-infer.sh` then `make`. Otherwise it's
not always clear what one should do to recompile infer, eg when `make` will
work and when `./build-infer.sh` should be used instead, in particular when the
user doesn't have opam configured for her terminal.

Summary:
This replaces the previous integration written in Python, which consisted in 1)
run the mvn command and parse its output to locate "directories containing
source files", 2) run on files named "*.java" in these directories. This meant
we had to run javac twice on each source file, and more importantly this
mechanism of finding source files was very fragile. In fact, I could not make
it work on several mvn projects I tried.
The new integration is based on parsing "pom.xml" to add an "infer-capture"
profile which instructs mvn to run `/path/to/infer` instead of `javac`. We also
add this profile to each maven submodule.
Users can specify an "infer-capture" profile themselves if the default one
doesn't work; in that case we don't inject our own "infer-capture" profile.

Summary:
This will make it easier to bisect on top of this commit, as values in
Makefile.autoconf.in are not expected to change across commits, but
Makefile.config may fluctuate.
This should also make it easier to rebase stacks of diffs without having
to rerun `./autogen.sh && ./configure`.
