Public API support for broadcasts and connectivity control.

* Three new DB fields, one indicating whether a download was initiated by the public API or not, two to hold connectivity control info.  DB migration to add these fields and code in DownloadProvider.insert() to handle them.
* Change broadcast intent code to match public API spec, for public API downloads only.  (Legacy code can go away once existing clients are converted over to the new API.)
* Introduce SystemFacade methods for sending broadcasts and checking package ownership; this facilitates new tests of broadcast code.
* Change DownloadInfo.canUseNetwork() to obey new connectivity controls available in public API, but again, retain legacy behavior for downloads initiated directly through DownloadProvider
* New test cases to cover the new behavior

Also made a couple changes to reduce some test flakiness I was observing:
* in tearDown(), wait for any running UpdateThread to complete
* in PublicApiFunctionalTest.setUp(), if the test directory already exists, remove it rather than aborting

DB changes for broadcast + roaming support
