Summary:
This is step further simplify the code to avoid cases where the summary of the procedure being analyzed can exist in two different versions:
# one version is the summary passed as parameter to every checker
# the other is a copy of the summary in the in-memory specs table
This diff implements:
# the analysis always run through the `Ondemand` module (was already the case before)
# the summary of the procedure being analyzed is created at the beginning of the on-demand analysis call
# all the checkers run in sequence, update their respective part of the payload and log errors to the error table
# the summary is store at the end of the on-demand analysis call

Summary:
Nuking the specs then building the models was not a great idea: the models do
not look at specs but only at some dummy marker files, eg
infer/lib/specs/c_models, so they don't necessarily realize that they need to
be rebuilt when the specs have been nuked!
One easy workaround would be to also delete the marker files, but then we would
*always* rebuild the models when building infer. Not good.
The solution here is to nuke the specs and marker files only when the clang
dependencies change, then rebuild all the models.

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:
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
