Add extra dereference when accessing fields that have T& type. It is similar
to what is done when accessing variables of T& type.
The only difference is that we need to handle constructor initializer list
separately (this is the only place where the field can be initialized)

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.

Summary:public
Add command-line argument --reactive to enable reactive propagation mode.
When the mode is active, the files changed during compilation are detected, and the analysis propagates reactively starting from the modified files.
The reactive mode allows to analyze a subset of the files in a project and follow their dependencies, without storing the results of previous analyses (specs files). Captured files are preserved from previous runs of the analysis (for example, when the previous analysis was the initial capture), so the mode can be used repeatedly while changing code.

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.

Summary:public
This is intended as a target to build during development when quick
compilation and no duplicate compilation warnings are desired.
This builds byte code for InferAnalyze, InferPrint, InferJava, and
InferClang. This is one ocamlbuild invocation, so builds (and reports
warnings on) each source file once. Building bytecode is currently
about twice as fast as native code.
The llvm frontend is currently not built by this since it requires
menhir and standard ocamlyacc is required by the backend, and ocamlbuild
can only use one at a time.

I have seen enough comments in this space by people during code review to switch on the analyses the compiler can already do. This diff is an automated renaming of unused identifiers to _, with a few additional changes made when reading the diff of the results for things that stood out as particularly strange. This base-lines all of the existing warnings. I'm not sure this is a good idea, since it might be better for those familiar with each part of the code to look at these warnings and use them as pointers to suspicious code.
