Summary:
It is unsafe to call protocol methods defined optional. Before calling them we should check it
the implementation exists by calling
`if ([object respondsToSelector:selector(...)]) ...`
Without the above check we get run time crashes.

Somehow clang now chooses slightly different arguments to pass to `ld`

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:
- Rename `invariantModels` to `purityModels`
- Track which arguments are modified in purity models. Before we were invalidating all arguments of impure modeled functions. Instead, now we only invalidate modified args given in the model. This should ideally result in more precision in the analysis.
- Add some more purity models for :`cast`, `new`, `new_array` and `Math.random`

Summary:
`infer_events` table is a key-value storage that also have list of fields common for entire infer run.
Infer should be agnostic of many of such fields (e.g. diff number).
Hence we will pass such extra fields through CI.
Note that only "normals" (strings in scuba terminology) are currently supported.
Reason being: most of things that are technically ints (like IDs) should actually be normals (because average etc does not make sense for them; and group by, in contrast, does).

Thanks to the newly added `StarField`, path length is better controlled before ondemand is used.

Summary:
Some edge case involving casting field pointers to the structure type itself generated arbitrarily long paths when used in a loop.
Without changing the widening, this diff avoids repetitions of fields in paths by abstracting them with a star.
E.g. `x.a.b.c.b` will become `x.a.b.c*.b`, and so will `x.a.b.c.a.b`, `x.a.b.c.c.b`, or `x.a.b.c.b.b`.
