Summary:public
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.

The analysis of the Buck project was failing because this script converts the aliases into their expanded target names. It turns out that for Buck, the name of the command is `buck` and the name of the alias is also `buck`, which led to conflicts. This is now fixed by only replacing the targets in the part of the command line that is after `build` in `buck build ...`

When no classpath was specified, Infer were considering it to be None instead of the current directory. The consequence is that we were replacing the current directory with the annotation processor for suppress warnings, leading to cases where `javac` was compiling fine but `infer -- javac` was failing with classes not found compilation issues. This diff fixes by always having at least "." in the classpath.

In the case of Java, the name of the method is enough to lookup the summary of the callees and run the symbolic execution. This revision separates the case of method call in Java and in C, C++ and Objective C. Most of the code for executing method calls was Clang specific and this is an intermediate step to be able to run the capture and analysis on demand.

With this change it will be possible to instruct Buck to not analyze certain files whose names match
with the regex passed in input.
So for example if you want to skip the analysis of files containing `skip_me` on their names, then
the command:
infer --use-flavors --blacklist-regex ".*skip_me.*" -- buck build <target-name>
will do it, because the `.*skip_me.*` regex will match the desired rule.

Summary: public
With this change, it will be possible to pass to InferAnalyze a list of folders to be
searched for spec files, through a file containing those paths, separated by the newline
character.
For example, if there's a `PathList.txt` file containing
/path/to/specs/folder1
/path/to/specs/folder2
/path/to/specs/folder3
Then invoking `infer --specs-dir-list-file PathList.txt [--other_args, ...] -- <build_cmd>`
will instruct the analyzer to lookup to those three folders whenever it searches for specs.
It's important to note that since the analyzer runs in parallel from different locations, it's necessary to pass **absolute** paths, or the analyzer will fail with an error.
