Summary:
Be more flexible in what type of function calls are allowed in `ViaCall ...` actions to be able to include models.
Also get rid of `here here` in traces /o\
As a side-effect, get more precise (=qualified) procedure names in
traces (but not in messages so as not to be too verbose).

Summary:
The domain supported path sensitivity wrt to a specific boolean guard `Branch.unlikely`. This isn't used in actual code, so remove it.
Also
- add an .mli to the domain;
- unabbreviate domain name to match analyser name;
- use Payload.read instead of calling Ondemand directly;
- adjust tests.

`CallGraph.ml` computes a call graph using the explicit procedure calls in the source code (ie computes a syntactic call graph)
I am going to be adding code for an 'analysis call graph' that gives the callees of a procedure from the perspective of the analyses in infer
