Summary:
It can be useful when debugging infer or the Makefiles themselves to see what
`make` is doing. Instead of editing Makefiles to remove `@` now you can `make
VERBOSE=1`.
This is just `git ls-files | grep -e Makefile -e '.*\.make' | xargs sed -e 's/^\t@/\t$(QUIET)/' -i`, and adding the definition of `QUIET` to Makefile.config.

Summary:
This was the one type of races we were not yet reporting (besides ones that use the wrong synchronization :)).
Wrote new utility function to aggregate all accesses by the memory they access.
This makes it easy to say which accesses we should report and what their conflicts are.
Eventually, we can simplify the reporting of other kinds of unsafe accesses using this structure.

Summary:
We can simplify the code now that the procedure callback are always executed through Ondemand. The procedure callback is still registered for Ondemand analysis by the time we run the cluster callbacks. This allows to run allows to run `Summary.read_summary`, which may run the analysis on-demand, while collecting the summaries for reporting errors.
This allows further simplifications of the Ondemand API.

Summary:
Don't pass names as strings in clang frontend. Instead use QualifiedCppName which preserves
each identifier of qualified name.
Done by
1. change return type of `Cast_utils.get_qualified_name` to return `QualifiedCppName.t`
2. change types in `Typ.Name.t` and `Typ.Procname.t` to use qualified names where applicable
3. Keep changing the code until it compiles

Summary:
Most of our tests work by comparing the output of some command to a baseline
expected output. It's often needed to update that baseline.
Previously, that was crudely done by attempting to move every foo.exp.test file
to foo.exp. This does not work terribly well, in particular because
foo.exp.test might be stale.
Instead, add a `replace` target to every test that knows how to update the
baseline. This allows custom behaviours too, eg in the differential tests.
Most of the tests include base.make or differential.make, so add a replace target
there. A few tests are completely custom, add a replace target to them too.

Summary:
This issue was spotted in the wild. There may be more of those, unfortunately it's hard to predict
More general problem is that types in infer frontend diverge from clang's types for DerivedToBase cast.
Then, infer uses types from clang anyway and that confuses backend. Getting it always right is very hard
