Summary:
One gets very obscure errors when trying to run infer for clang when it was
compiled for Java, or vice-versa. This diff makes sure we crash early with the
appropriate error message. For instance:
```
$ ./build-infer java
$ infer -- clang -c hello.c
Uncaught exception:
(Failure
"Unsupported build mode: make/cc\
\nInfer was built with clang analyzers disabled.\
\nPlease rebuild infer with clang enabled.\
\n")

Summary:
- inferbo introduced a dependency to extlib. When building Java analyzers, this
is implicitly pulled in by javalib, but it's missing when building only the
clang analyzers. Add `extlib` to the packages we build against.
- infer.ml and Javac.ml depend on Javalib, but it's easy to push down the code
that needs it to `jMain.ml` so that we can build without javalib for the
clang-only case.
- jMain.mli had 2 copies: one in java/ and one in java_stubs/. Make one a symlink to the other.

Summary:
Native compilation seems to take a couple of seconds to build the unit test
binary, but we don't need it to be native (and neither do users building infer
to install it on their machines). In fact, the test mode rebuilds it in
bytecode mode. For the sake of being able to run the unit tests when developing
on infer (and thus possibly while having some fatal warnings showing up in the
code, preventing us from building the test target), also build InferUnit in
bytecode mode.

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:
1. One call to `Core.Std.String.slice` was wrong and caused the program to crash, and
2. The crash was silently ignored because the error code of uncaught OCaml
exceptions was the same as `CheckCopyright.copyright_malformed_exit_code` (=2)
Address both issues. Also build CheckCopyright with debug options.

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:
C stubs were causing issues with building:
- need OCaml stubs of the C stubs for byte compilation!
- brittle (to remain polite) support in ocamlbuild
Ctypes is awesome, use it instead.
Slight wrinkle on the previous statement:
- ioctl(2) is variable arguments, which is not officially supported by Ctypes but should work in our use-case
- I'm hardcoding the value of a C macro found in system headers

Summary:
This removes support for developing infer using Eclipse. If you use Eclipse,
consider using Atom/Emacs/vim instead, which have good OCaml/Reason support.
This allows us to get rid of a couple quirks:
- do not generated ocaml annots (this is very slow)
- move OCaml _build directory to infer/src/ where it makes more sense

Summary:
Use In_channel and Out_channel operations instead of those in Pervasives. Don't
use physical equality on values that aren't heap-allocated since it doesn't help
the compiler generate faster code and the semantics is unspecified. Also use
phys_equal for physical equality.

InferClang knows what to do if its name ends in ++. So it is not
necessary to pass whether or not the original clang executable ended in
++ to InferClang using the the INFER_XX environment variable. Instead,
create an InferClang++ symbolic link and make the clang wrapper call
either InferClang or InferClang++ as needed.

Summary:
This diff adds a make target to generate interface files from
implementation files. These generated interface files can then be used
as a starting point for documenting and restricting the exposed module
interface. For example, to generate an interface for JavaTaintAnalysis.ml,
execute:
```
make -C infer/src M=quandary/JavaTaintAnalysis mli
```
Note that this relies on `ocamlc -i`, which for reason currently
produces syntactically ill-formed files.
