Summary:
Fix an issue where, when `-reactive` mode is used, files captured in the first second are not considered modified, and are not analyzed. This happens because file timestamps are used, and the resolution is one second.
Change the front-ends to change the timestamp of the directory where artifacts are created, so that the timestamps are 1 second in the future.
Small reactive commands such as the following now analyze correctly:
rm -rf infer-out && infer --reactive -- clang -c test.c

Summary:
Declared and defined procedure attributes are now saved in different files (hashed_name.decl.attr and hashname.attr).
We always try to load using the filename of defined procedure attributes first,
and fall back to loading the file for declared ones if it does not exist.
The logic for replacing an existing file stays the same, with one extra thing:
when a file for a defined attribute is written, the one for the declared one
is deleted if it exists.
At the end of a capture, either a declared or a defined file exist, but not both.
The reason for this change is that when captures of different subprojects are
merged together, it can happen that a link gets created to a declared attributes
file even though a defined one exists, so the body of the procedure will not be analyzed.
After this diff, both links will be created, and the defined one will be loaded
by the back-end.

Summary:
We updated the version of Reason, which removes the need to pin
reason/merlin/merlin_extend. In fact, the pinning we used to do breaks the
compilation as the version of reason is too old. We don't need to pin anymore
to get the right version of Reason, so simply remove the `opam pin ...` setup
commands (as was done for ./build-infer.sh).

Summary:
Create dummy functions representing the initializers of global variables. This
is so we can implement checks in the backend that can look at the initializer
expressions of global variables. We try not to create these dummy functions
when the initializer is not present, although for some reason we sometimes end
up with empty initializers.
Also add source file info to global variables in the backend (Pvar.re).

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.

The formulas, expressed using the notation of CTL (https://en.wikipedia.org/wiki/Computation_tree_logic) are represented in a graph alongside the current ast-node and their final evaluation result (green for true, red for false)
To get the dotty graph, run infer with the `--debug` flag
