First pass at a functional test for the Download Manager.

This "Large" test sets up an HTTP server on the device using
MockWebServer and then initiates downloads from that server through
the download manager.  It uses ServiceTestCase to control the
construction and execution of the DownloadService, and it uses some
logic from ProviderTestCase2 to construct a DownloadProvider and a
ContentResolver that uses it.

This setup gives us some ability to mock dependencies.  This commit
includes use of a fake ConnectivityManager to test responses to
connectivity changes, and use of some customizations to MockWebServer
to test resuming an interrupted download.  This test is disabled,
though, since it requires a very long sleep.

Avoiding that, and achieving certain other things, will require
changes to the Download Manager code itself to introduce new seams.  I
wanted to check this in before I started such changes.
