Summary:
Turns out that swapping stdout and stderr using a temporary fd 3 was screwing
up with make's jobserver, who also uses fd 3!
Also, infer is partly to blame as it also calls `make`. Unsetting `MAKEFLAGS`
in infer tells `make` that the way infer calls `make` is independent from
parent `make` invocations.
Also, simplify the rules for direct tests and build system tests.

Maintain an "ownership" set of access paths that hold locally allocated memory that has not escaped.
This memory is owned by the current procedure, so modifying it outside of synchronization is safe.
If an owned access path does escape to another procedure, we remove it from the ownership set.

This diff introduces place-holders strings in error messages and evaluates them
when an error needs to be reported.
Place-holders strings are of the form %name_of_helper_function%. They will be evaluated
using and helper function that gives a value.
For example if we need to display the name of a variable in the error message we will have:
".... %var_name%...."
then %var_name% will be evaluated in the ast node calling the appropriate
helper function and the results will replace %var_name% in the message.

C stubs were causing issues with building:
- need OCaml stubs of the C stubs for byte compilation!
- brittle (to remain polite) support in ocamlbuild
Ctypes is awesome, use it instead.
Slight wrinkle on the previous statement:
- ioctl(2) is variable arguments, which is not officially supported by Ctypes but should work in our use-case
- I'm hardcoding the value of a C macro found in system headers

Temporarily redirect stderr to /dev/null before calling `Javalib.get_class` so
as to avoid getting spammed with "Warning: unexpected attribute: Code" messages
when parsing Java files.

I suspect that now that Javalib handles Java 8 this issue is more prevalent. An
issue/PR should be sent to Javalib too so that it's fixed upstream and we can
eventually remove the hack (t15039096).

Summary:
Before, the Interprocedural functor was a bit inflexible. You couldn't do custom postprocessing like normalizing the post state or coverting the post from an astate type to a summary type.
Now, you can do whatever you want by passing a custom `~compute_post` function.
Since `AbstractInterpreter.compute_post` can be used by clients who don't care to do anything custom, this doesn't create too much boilerplate.
