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.

Make the html output available to checkers when -g is used on the command-line.
A checker needs to call a function to start and finish the processing of each node,

Summary:
Previously, we would first compute which build command is at hand, based on the
first argument after "infer --", then do everything depending on that piece of
information. However, the build command alone is not enough to know in which
"build mode" we are operating. For instance, there are several build modes
corresponding to "buck" build commands.
This led to duplication of the logic (to retrieve which build mode we are in in
the various phases of an infer run), and some invariants that had to be
re-asserted at various points in the code, eg that the arguments are not empty.
This diff adds a `build_mode` type (renaming the previous `build_mode` to
`build_system`) that identifies the various integrations we support. We compute
the build mode at the start of infer, then pass the build mode around.
Also, move `run_javac` to a new `integration/Javac.ml` file given that it's a
bit large.

Summary:
If an access path rooted in some parameter `p` is accessed outside of synchronizaton, but `p` is owned by the caller, then we should not warn.
We will implement this by separating writes into "conditional" (safe if a certain parameter is owned by the caller" and "unconditional" (safe only if the caller synchronizes appropriately).
This diff just introduces the map type for conditional writes and changes the transfer functions accordingly.
We'll actually use the map in a follow-up.

This makes it more obvious why infer would force a path to be absolute since we
base that decision on the resolved path. For instance:
```
$ mkdir foo
$ cd foo
$ ln -s ../examples goo
$ infer -- clang -c goo/hello.c
[...]
/home/jul/infer/examples/hello.c:14: error: NULL_DEREFERENCE
```
We see that the path is outside of the current directory clearly, whereas
before infer would report on "goo/hello.c".

Summary:
`make byte` will populate infer/bin/ with bytecode version of each executable,
plus infer/bin/infer.byte (used to remember which of the native or byte
executables have been built most recently). `make infer` now also creates
infer/bin/infer.native, so that we're sure to replace the executables with
native/byte versions as appropriate.
This is to make debugging a tad easier:
make byte
ledit ocamldebug $(which infer) <infer args>
Whereas previously one had to:
make -C infer/src byte
ledit ocamldebug infer/_build/infer/backend/infer.byte <infer args>

Summary:
Currently, if we don't find `-d` or `-classes_out` on the command line then we
tell javac to redirect the compiled classes in some other directory, by default
the initial working directory. But we don't detect when these arguments are
hidden inside files (`foo` arguments on the javac command line) so the
heuristic was incomplete. Look inside these files to better tell whether we need
to make up an output directory or not.
