Pointer support and embedded types in HIDL.
* Pointers work per transaction. Don't work
across transactions.
* ref<T> in HIDL translates to T const* in C++.
* No Java support.
* Embedded types like ref<vec<vec<int32_t>>>
or vec<ref<T>> is supported. Pointers to
pointers like ref<ref<ref<T>>> is supported.
* Array of pointers and pointer to array supported.
* Pointer inside a union is NOT supported.
Test: `mma`
Test: `make hidl_test && adb sync && adb shell hidl_test`
Note that this only works with a kernel patch.
