Summary:
Just a bunch of minor changes.
- The mutable field doesn't need to be mutable: it's only mutated once in the code somewhere that doesn't even need to mutate
- Hence the type can be public
- All the `ms_get_*` functions are replaced by field accesses
- `CMethod_signature` -> `CMethodSignature` while I'm at it, although maybe that's bad since other files in clang/ follow the former convention
- `type method_signature` -> `type t`
- `pp` function instead of `to_string`, since it's used with `fprintf`. This gets rid of the only caller of `IList.to_string`.

Summary:
Instead of storing the type environment in infer-out/captured/foo.c/foo.c.tenv,
store it in the `source_files` table of the SQLite db. This limits the number
of files we create on disk.
The "file local" type environemnts are specific to the clang integration. For
Java, there is a "global tenv" file. Instead of matching on string names, this
diff also makes the API of `Tenv` reflect this situation.
The global tenv is serialized as a separate file in "infer-out/.global.tenv"
instead of "infer-out/captured/global.tenv", because "infer-out/captured/" will
soon be removed as it now only contains the global tenv (except in debug mode,
where it will still be created).
In the DB, we either store the local tenv for the file, or "global" to indicate
that the global tenv should be consulted.
This diff also moves `Cfg.store` to `SourceFiles.add` because that function
deals with more than just `Cfg.t`.

Summary:
In some cases infer runs clang commands where we do not attach the plugin,
notably for pre-processor-only commands like `clang -E foo.c`. Usually these
commands are used by build systems to test their output, so infer should not
swallow it.
This makes infer echo the stdout of clang whenever we do not attach the plugin
to clang. When the plugin is attached, stdout is captured because that's where
the plugin outputs its results, so we cannot do the same in this case (not that
we would want to yet).

Summary:
The diff is very big but it's mostly removing code. It was inspired by the fact that we were getting Dead Store FPs because we were modeling some functions from CoreFoundation and CoreGraphics directly as alloc in the frontend, which caused the parameters of the function to be seen as dead. See the new test.
To deal with this, if we are going to skip the function, we model it as malloc instead. Given how many models we had for those "model as malloc" functions, I removed them to rely solely on the new mechanism.
The modeling of malloc and release was still based on the old retain count implementation, even though all we do here is a malloc/free kind of analysis. I also changed
that to be actually malloc/free which removed many Assert false in the tests. CFRelease is not exactly free though, and it's possible to use the variable afterwards. So used a custom free builtin that only cares about removing the Memory attribute and focuses on minimizing Memory Leaks FPs.
Otherwise we were translating CFBridgingRelease as a special cast, and this wasn't working. To simplify this as well, I removed all the code for the special cast, and just modeled CFBridgingRelease and CFAutorelease also as free_cf, to avoid Memory Leak false positives. I also treated the cast __bridge_transfer as a free_cf model. This means we stopped trying to report Memory Leaks on those objects.
The modeling of CoreGraph release functions was done in the frontend, but seemed simpler to also simplify that code and model all the relevant functions.

Summary:
This resolves#796 . Effectively it adds file specific suffix to name of all global initializers (so initializersof two global variable of the same name will have unique Typ.Procname). which is the same rule as currently used by constructing Procname for the static functions. However this change applies to initializers of all global variables and not just static (arguably it's a right thing. since GCC used to allow multiple global variables with the same name).
Consequences of this change that it becomes impossible to know name of generated initialization function of global ('extern') variables. However get_initializer_pname function is only referenced by the frontend (when creating initializer for the defined global variables) and by the SIOF checker.

void foo() {

Replacing `std::tuple<std::tuple<int>>` by `std::tuple<int>` makes the analysis
terminate.
In the AST, both tuple<tuple<int>> and tuple<int> have the same template
specialization type: "Pack" (which means we're supposed to go look into the
arguments of the template to get their values). This is not information enough
and that's the plugin fault.
On the backend side, this means that two types have the same Typ.Name.t, namely
"std::tuple<_>", so they collide in the tenv. The definition of
tuple<tuple<int>> is the one making it into the tenv. One of the fields of the
corresponding CxxRecord is of type "tuple<int>", which we see as the same
"tuple<_>", which causes the loop.

The behaviour of infer was observed to be different in 4.04.2 vs (4.05.0 or
4.04.2+flambda). Investigating further, the behaviour is also different in byte
vs native versions of infer under 4.04.2. Looking at the Changelog of 4.05.0
(thanks mbouaziz), there are fixes for inconsistent behaviours between byte
and native relative to evaluation order.
Lots of debugging later, this 1 line patch is born. Also use `List.concat_map`
instead of re-implementing it.

Summary: With Logging.exit you have more control of the code that invokes exit, for example when forking and running certain functions that may in turn invoke exit, and you want to handle the execution flow differently - like invoking certain callbacks before exiting, or not exiting at all.

Summary: This will prevent trivial errors like misspelling node names, e.g. when those are typed as part of the operators `IN-NODE <node-name>` or `HOLDS-IN-NODE <node-name>`

Summary:
Not translating these properly was causing false positives for the dead store analysis in cases like
```
int i = 0;
return [j = i]() { return j; }();
```

Summary: Refactoring destructor translation to take type pointer instead of qual type as a parameter, as we only have type pointers for base classes.

Summary: We used to crash whenever we hit these. The simple translation implemented here is not particularly inspiring, but it is better than crashing.
