Summary:
Equality relies on the result of solving an equation to be a "solution
substitution". In constrast to unconstrained Map's, solution
substitutions are idempotent and have constraints on the terms that
may appear in their domain (they must be "maximal solvables", that is,
variables or uninterpreted function applications, which would be
variables if explicit "variable abstraction" was done).
This diff factors out the manipulation of concrete Map's into a
Equality.Subst module, and uses these for the result of `solve`.

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.

`clang.make` does this, but `java.make` was missing the flag which led

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.
