Remove option to filter source files from being analysed from clang wrapper.
The option is unused and there should be better mechanism to do so if we need it.
This will slightly simplify the script and allow to analyze files that are from
outside of "blessed" extensions (such as .cxx or .hpp)

This create `make install` and `make uninstall` targets that can be used to
install Infer on a system. All the files needed are installed under
"/usr/local/lib/infer" (by default, but can be configured with ./configure
flags as usual), pretty much like their git infer/ counterparts. Moreover,
"infer" and "inferTraceBugs" are installed in /usr/local/bin (similarly
configurable).
As a bonus, `opam install infer` and `opam remove infer` now work. To use
these, it's better to pin the git repo with "-k git":
cd ~/infer/ # where the repo is
opam pin add -k git --yes infer .
The reason is that otherwise, and only if the repo is not clean, opam will
convert symlinks into regular files, which is not good (compilation will fail).

Instead of `CC=/path/to/infer/infer/lib/capture/clang cmake .`, which is what

that the number and types of arguments are part of the call instruction, so they can

Summary:public
The option -merge_captured specifies that this is merging the results of capture
using the buck integration. The file specifying the targets is read from `infer-out/infer-deps.txt`.
Each dependency specifies a path in buck-out for one target:
where the results directory after capture is.
The option triggers a merge of the results directories into infer-out.
The merge consists in making a virtual copy, where each file in a
target in `buck-out` gets virtually copied into infer-out by making
one symbolic link per file.
There is a mechanism to detect when the capture of a target has already
been copied: when each source file already exists at the destination.
There's also an option `-modified_targets modified_targets.txt`.
If a target is listed in `modified_targets.txt`, this will force a new creation of links
for that target, whether those links exist or not.

Assert false have been observed in Procname when analyzing some C projects.
This diff changes the Procname API to make it safe for Java: the java functions in the module don't assert false now. This takes care of the errors observed in C projects.
The new API forces changes throughout the codebase. In particular, the constant propagation module was making assumptions that it would only be executed on Java code, triggering assert false on C. Now it is safe.
For the remaining functions in the Procname module, those for other languages, a special assert false in Utils is used to print stack traces. This is for future debugging.

The first dealing with all the expressions and the latter dealing with all
the declarations (in a later diff, we may want to change names of these moules
to reflect Expr and Decl).
This structure will enable to implement lambdas. The previous version

With the --continue option, the capture is continued: all the files/procedures marked

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.
