Fix warnings

First, update our various project-specific Eclipse compiler settings
configuration files to include the new Eclipse 4 flags.

Second, turn off the "Unchecked conversion from non-annotated type to
@NonNull" warnings; there are hundreds or thousands of these, and
there isn't much we can do about them when they're coming from
platform and library APIs.

Third, make the lint projects warning-clean again by addressing
various warnings Eclipse found (such as some unclosed resources and
some null handling issues; yesterday's null annotation fixes only
addressed errors, not warnings.)
