Summary:
Previously, _override resolution_ considered only the number of
arguments. This led to many FPs in nullsafe's _Inconsistent Subclass
Annotation_ check.
Current version also checks that argument types match. However, we
still don't handle type parameters and erasure, so in this sense the
rules are incomplete.

Summary:
You should use `--buck-java` instead, which uses the new "genrule
master" integration.
This diff makes it impossible to select the previous integration.
Upcoming diffs will clean up the resulting dead code.
This also make infer fail hard when no buck mode is specified in a buck
capture command, eg `infer -- buck build //foo:foo`. The reason is that
we need to choose between 3 incompatible integrations and making any of
them the default will confuse at least one person in the future.

Summary:
`infer/tests/infer.make` unconditionally runs
```
$(call check_no_duplicates,$(INFER_OUT)/duplicates.txt)
```
as a part of `test` target. This requires the flag to be set to
produce `duplicates.txt`.
`clang.make` does this, but `java.make` was missing the flag which led
to an error on running `make tests` within
e.g. `tests/codetoanalyze/java/nullsafe-default`:
```

Summary:
This diff avoids that null-retuned path's abstract value ruins that of non-null-returned path.
What this diff does is: when joining two abstract states, one is null-return-path and the other is
non-null-return-path (`return obj;`), it keeps the method calls of `obj` from the
non-null-return-path.
While this design is unsound, I think it should work in practice.

Summary:
As part of enabling substitution of arguments into lock names in summaries, and potentially changing the equality relation over locks (so that we can eventually make equal `x.f.g` and `this.f.g` for example), the lock type needs to be elaborated so that the root of an access path is classified into:
- global variables are clearly separated from all other classes (invariant to substitution)
- class objects are also separate (also invariant, but identified by type)
- all other parameters remember their positional index (so that substitution becomes easier)
For now the comparison/equality is kept identical, so as to make easy CI comparisons.

Demonstrate that the per-file type environments don't prevent
the deadlock report here. The fear was that when the analyser
tries to locate the methods of the endpoint class, it might fail to
do so because the types might be stored in different type

Summary:
This changes how we select amongst our (currently) 4 Buck integrations
for Java and clang, as well as how the user's choice is reflected by the
Config module.
The old command line interface is still supported but is now deprecated.
The changes in how to select each integration are:
- clang via "flavors", activated with `--flavors`, now with `--buck-clang`
- clang via "compilation DB", activated with `--buck-compilation-database`, unchanged
- Java via "genrule", activated with `--genrule-master-mode`, now with `--buck-java`
- Java "without genrules", used to be activated by *not specifying any other Buck mode*, unchanged
Instead of various `Config` flags corresponding to the previous CLI that
are allowed in any combination of `flavors`,
`buck_compilation_database`, `genrule_master_mode`, `Config` now exposes
a single `buck_mode` datatype. This allows, eg, `flavors` to override
`buck_compilation_database` if needed. It will also make it easier to
get rid of the old "Java without genrules" integration in a later diff
(see inline comments).
