Summary:This enables controlling the encoding chosen by infer via the usual environment
variables. For instance:
```
LC_ALL="C" infer ... # sets LOCALE to "ascii"
LC_ALL="en_US.UTF-8" infer ... # sets LOCALE to "UTF-8"
```
This gives an easy solution to #320: run `LC_ALL="en_US.UTF-8" infer ...`.
Right now the only solution is to edit the Python scripts by hand instead!

Simplifies the way to configure cmake to run infer's fake compiler commands.
Instead of `CC=/path/to/infer/infer/lib/capture/clang cmake .`, which is what
is advised on #25 and is now outdated because the paths to infer's clang has
changed since, simply run `infer -- cmake .`. The only caveat is that infer
tries to analyze the end result, and prints "No issues found". This could be
fixed later.

Eradicate need the procedure attributes for callees.
It relies on the java front-end to create proc descs for callees that are declared but not defined.
This diff remove that needs, and when a callee without prodedure attributes is found, it creates one on the fly. The attribute created is similar to what the Java front-end would do, except
that the number and types of arguments are part of the call instruction, so they can
be used to create the formal parameters.

In Python 2, `shutil.rmtree()`, `os.walk()`, `os.path.join()`, etc. are not
happy when the locale cannot decode the filenames they have to deal with.
Decrease the likelihood of this happening by making the file names generated by
infer ascii-only.
Also ignore character decoding errors optimistically when reading the json
report file.
Add tests that we are able to run the analysis and report the bug on a function
with a utf8 name, and that we are able to remove the previous results
directory.

The reactive analysis starts from the set of changed files/procedures, and proceeds
reactively to analyze their dependencies.
This means that after every command, the set of changed files/procedures is reset.
With the --continue option, the capture is continued: all the files/procedures marked
as changed stay changed, plus any additional changes are recorded.
In addition to allowing to spread capture over several commands, the option also allows to separate capture and analysis in reactive mode, or to repeat the analysis.

Instead of using the collection of suppress warnings annotations to filter out the errors while generating the error reports, we just add this SuppressWarnings at translation time, like any other annotations, and the reporting functions in the Reporting module will just skip the errors when the method is annotated with SuppressWarnings.

Lazy dynamic dispatch handling works as follows:
Assuming a call of the form:
foo(a);
where the static type of `a` is `A`. If during the symbolic execution, the dynamic type of the variable `a` is `B` where `B <: A`, then we create on-demand a copy `foo(B)` of `foo(A)` where all the uses of the typed parameter `a` are replaced with a parameter of type `B`. Especially, if `foo` contains virtual call, say `get` where `a` is the receiver, then the call gets redirected to the overridden method in `B`, which simulates the runtime behavior of Java.
This lazy dynamic dispatch mode is only turn on for the tracing mode for now in order to avoid conflicts with sblackshear's approach for sound dynamic dispatch.

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.

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.
