Support @Nullable annoations marked with @Target({TYPE_USE})

[nresare]

Java support for annotation metadata has evolved, and projects providing
implementations of @nullable has been adopting those new features. This
has had the side effect of some commonly used @nullable annotations not
working as expected with Guice. This change uses reflection to extract
new style @nullable annotations as well as old style ones. Addresses
the issue described in #1193

1a410a8 has done some work for type annotations. That may be sufficient for your needs (though I don't believe there's been a release yet).

Indeed that commit already fixed this.
