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).

Somehow clang now chooses slightly different arguments to pass to `ld`
in the invocation that `ndk-build` makes to link:

In particular:
- `lc++` results in `libc++.so` not found from the toolchain
- the forced relocation `-z relro` fails with "/..//bin/ld: ./obj/local/arm64-v8a/objs/hello/__/hello.o: Relocations in generic ELF (EM: 183)" and other weirder errors
Somehow pretending the C++ compiler is `clang` instead of `clang++` stops the insanity.
Also add an Application.mk file to specify some sane defaults.
Also add `V=1` to the `ndk-build` invocation in our tests so that when it fails we have a bit more to work with.

Summary:
Previously, the command parsing code filtered out any elements that were `False`y in the Python sense (starting with D5507925).
This meant that a command like `javac -classpath '' -Xmaxerrs 1000 MyFile.java` would be parsed as `javac -classpath -Xmaxerrs 1000 MyFile.java`, which will fail with "unrecognized option 1000".
This diff removes the filtering and fixes that issue.

It's already turned of systematically for the Java integration, this just

Summary:
This is to fix the conflicts between Eradicate and the Biabduction when reporting the same kind of errors: when Eradicate is on, the Eradicate warnings will have priority over the null deference reported by the biabduction.
If this approach proved to be successful in prod, I will refactor the reporting mechanism in the analysis itself to simply not report the null dereference in this case at all. For the codebases that aren't yet fully consistently using `Nullable`, this combined approach looks like a good way to deploy Infer toward full null safety.

Summary:
Instead of storing the type environment in infer-out/captured/foo.c/foo.c.tenv,
store it in the `source_files` table of the SQLite db. This limits the number
of files we create on disk.
The "file local" type environemnts are specific to the clang integration. For
Java, there is a "global tenv" file. Instead of matching on string names, this
diff also makes the API of `Tenv` reflect this situation.
The global tenv is serialized as a separate file in "infer-out/.global.tenv"
instead of "infer-out/captured/global.tenv", because "infer-out/captured/" will
soon be removed as it now only contains the global tenv (except in debug mode,
where it will still be created).
In the DB, we either store the local tenv for the file, or "global" to indicate
that the global tenv should be consulted.
This diff also moves `Cfg.store` to `SourceFiles.add` because that function
deals with more than just `Cfg.t`.

Summary:
In buck queries, the `regex` in `kind(regex, ...)` is open, it can match superstrings, like `prebuilt_cxx_library` when we want `cxx_library` instead.
This adds `^` and `$` to our existing kind filtering.
Also optimizes the query in `buck_target_determinator.py`.
