Summary:
This makes sure that one can run `./build-infer.sh` then `make`. Otherwise it's
not always clear what one should do to recompile infer, eg when `make` will
work and when `./build-infer.sh` should be used instead, in particular when the
user doesn't have opam configured for her terminal.

Summary:
Procnames files are now reversed qualifier lists with `#` as separator (instead of `::` which needs to be escaped in bash).
Because of the mechanism that is used to obtain qualifiers, it also affects naming for ObjC classes.
Examples:
```
std::unique_ptr<int>::get -> get#unique_ptr<int>#std#__MANGLED,...__ // C++ method
folly::split -> split#folly#__MANGLED,..._ // function within namespace
NSNumber numberWithBool: -> numberWithBool:#NSNumber#class // ObjC method
```

Summary:
We want to stop supporting '-multiletter' options altogether in the future as
they are not standard.
For boolean switches, we used to have '-short' for true and '-nshort' for
false, but that second form is necessarily > 1 letters, which doesn't work in
this scheme. Replace these by '-s' for true and '-S' for false.

Summary:
When both an unprotected write and a read/write race emanate from the same line,
undoubtedly because of interprocedurality, strip the read/write report (for now).
Perhaps report the info in more succinct form later, but keep to one report/line.

There was a bug where we allowed ourselves to project local variables from the callee summary into an access path in the caller.
We should only be able to project callee variables that are in the footprint.

Summary:
Eradicate detects circular field initializations (e.g. a field initialized with itself)
by checking in the typestate at the end of the constructor whether the origin
of the field is a field name in the current class.
This has the problem that the following initialization pattern is not recognized as correct:
C(C x) { this.field = x.field }
To fix the issue, the origin information for field accesses x.f is extended
with the origin information of the inner object x.
Circularities are detected if the origin of x is "this".

Enrich the domain of SIOF to contain, as well as the globals needed by a

Summary:
I couldn't figure out why, but from within an infer release the traces we get
for this test are different than the expected ones. This is even consistent
across osx and linux.
In order to restore sanity, let's just hide this incomprehensible fact. Let's
come back to it if more tests exhibit this, maybe traces are not guaranteed to
be exactly the same across runs.
