Summary:
First steps towards implementing diff analysis functionalities inside infer
itself. What works: run infer, checkout parent, re-run infer, checkout top
revision, compute the reportdiff (but no final surfacing on the console). Lots
of TODO still, inlined in the code.

Summary:
Spacetime profiling showed that this was allocating a lot more than it needs
to. Switching to a `Hashtbl` makes the memory overhead go away, and halves the
memory consumption of the whole frontend on some pathological files.
This also brings the file "clang_ast_main.ml" into the infer repo, renamed to
"ClangPointers.ml" (and given an mli). It's useful to have something like
"clang_ast_main.ml" checked into the facebook-clang-plugins repo to illustrate
how to use the OCaml AST visitor generated by atdgen, but it can be simplified
to be more pedagogical instead of being the visitor used in infer.

Summary:
Recently we changed the binaries we build and use but it wasn't obvious that
some of the old binaries disappeared. For instance, nothing short of `git clean
-xfd` would get rid of "infer/bin/InferPrint", which can lead to frustrating
attempts to make InferPrint not segfault.
Mitigate this in two ways:
- be more strict in the binaries we ignore in .gitignore, so InferPrint would should up in "git status"
- be less strict in the binaries we clean out with `make clean` so that
InferPrint et al. gets deleted by `make clean`

This enables the following workflow:
```
$ ./build-infer.sh
[...]
$ opam upgrade # takes infer dependencies into account
```
To do so, we install a temporary `infer-deps-XXXX` package as before (the temp
name is because opam thinks there's nothing to do otherwise), then we install
an `infer-deps` package permanently.

Summary:
Nuking the specs then building the models was not a great idea: the models do
not look at specs but only at some dummy marker files, eg
infer/lib/specs/c_models, so they don't necessarily realize that they need to
be rebuilt when the specs have been nuked!
One easy workaround would be to also delete the marker files, but then we would
*always* rebuild the models when building infer. Not good.
The solution here is to nuke the specs and marker files only when the clang
dependencies change, then rebuild all the models.

Summary:
Given two analysis results, it's now possible to compare them with the following command:
infer --diff --report-current reportA.json --report-previous reportB.json --file-renamings file_renamings.json
this command will then generate 3 files in `infer-out/differential/{introduced, fixed, preexisting}.json`, whose meaning is the following:
- `introduced.json` has all issues in `current` that are not in `previous`
- `fixed.json` has all issues in `previous` that are not in `current`
- `preexisting.json` has all issues that are in both `current` and `previous`
The json files generated can then be used to categorise results coming from incremental analyses of a codebase.

Xcode's compilation databases follows a different convention than cmake's and
escape the `"file"` and `"dir"` fields of each unit to make them shell-ready.
We need to treat them differently when reading them.
This adds a new `--clang-compilation-db-files-escaped` option and makes the
code related to reading compilation databases deal correctly with both
conventions.

Summary:
This replaces the previous integration written in Python, which consisted in 1)
run the mvn command and parse its output to locate "directories containing
source files", 2) run on files named "*.java" in these directories. This meant
we had to run javac twice on each source file, and more importantly this
mechanism of finding source files was very fragile. In fact, I could not make
it work on several mvn projects I tried.
The new integration is based on parsing "pom.xml" to add an "infer-capture"
profile which instructs mvn to run `/path/to/infer` instead of `javac`. We also
add this profile to each maven submodule.
Users can specify an "infer-capture" profile themselves if the default one
doesn't work; in that case we don't inject our own "infer-capture" profile.

`make byte` will populate infer/bin/ with bytecode version of each executable,
plus infer/bin/infer.byte (used to remember which of the native or byte
executables have been built most recently). `make infer` now also creates
infer/bin/infer.native, so that we're sure to replace the executables with
native/byte versions as appropriate.
This is to make debugging a tad easier:
make byte
ledit ocamldebug $(which infer) <infer args>
Whereas previously one had to:
make -C infer/src byte
ledit ocamldebug infer/_build/infer/backend/infer.byte <infer args>

Instead of the custom filtering done by `InferPrint --issues-tests`, use the
filtering done by `infer` and run without filtering for our e2e tests. We still
test the filtering for our build systems integration tests, and this diff
restores that behaviour for the ant test (hence the bugs removed from
ant/issues.exp).
Also add internal exceptions to most tests to get more signal out of them (eg,
knowing when we add assertion failures and the like).
Retire the old `--issues-tests` to limit the number of ways we do filtering.
