Summary:
Use an SQLite database to store proc attributes, instead of files on disk.
Wrap SQLite operations in two layers:
1. `SqliteUtils` provides helper functions to make sure DB operations succeed
2. `KeyValue` provides a functor to expose a simple and type-safe key/value store backed by the SQLite DB.

Summary:
This simplifies the jbuild files: no need to list these files explicitly
anymore, nor to exclude them explicitly from the main `InferModules` library
(due to their different compilation flags).
Isolate common parts into jbuild.common do `cat`-based code inclusion into
jbuild files to factorize code.

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.

This changes a bunch of things that were hard to break up from the diff, so the
resulting diff is big.
Use `Cmdliner.Manpage` to format man pages (and also format a bit ourselves
since it is so stubborn).
As a bonus, introduce the following subcommands:
```
infer run ... # same as default mode with -- before
infer capture ... # -a capture
infer compile ... # -a compile
infer analyze ... # InferAnalyze
infer report ... # InferPrint
infer diff ... # this one is not new
infer clang ... # InferClang, not that you should use it

`ENVIRONMENT`, stuff about .inferconfig, some example usage, `DESCRIPTION`, ...

There are 2 possible places where to find toplevel.cmo:
- infer/_build/infer/toplevel.cmo, built by `make toplevel`
- infer/_build/test/infer/toplevel.cmo, built by `make test`
The test loading and running toplevel.cmo would give priority to the non-test
version of toplevel.cmo, which might be stale because `make test` doesn't
rebuild it.
This diff makes sure we use the test version of toplevel.cmo in `make test`.

- Which formula is being evaluated
- In which part of the AST is such formula being evaluated
- Line number of the source file
- Whether a CTL-Transition will take place or not
- Node-ID that can be related to the dotty file containing the evaluation graph (the one in infer-out/lint_dotty/)
The AST is shown with coloured nodes, where each colour has the following meaning:
- [Default terminal colour], Bold: The node is being evaluated
- Green, Bold: The formula returned true on the current node

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.

This attempts to properly sanitise text input/output in the Python parts of
infer. Do three things:
- encode user input (coming from the command-line or reading files)
- decode infer output
- in both cases, we may be using the wrong encoding, eg: locale says we're in
ascii, but the source code contains utf-8. In many cases, like error
messages, it's safe to ignore these encoding mismatches.
Also, since we `import __future__.unicode_literals`, it's safe to remove `u'`
prefixes on many unicode literals.

Adds test_build target to toplevel Makefile, which compiles
InferAnalyze, InferPrint, InferClang, and InferJava where warnings
listed in OCAML_FATAL_WARNINGS defined in infer/src/Makefile are fatal.
Other builds do not treat warnings as fatal. The test build is
performed in parallel with the tests by scripts/test.sh. This makes
refactoring and debugging easier, but prevents warnings from slipping
into the repo.
Also, make test target robust wrt parallel make.
