Bug 1291363 - Add geckoview and geckoview_example Gradle projects. r=jchen,sebastian

include new test dependencies; and use freshly uploaded tooltool
archives (manually uploaded) containing the new test dependencies.

+// We run fairly hard into a fundamental limitation of the Android Gradle
+// plugin.  There are many bugs filed about this, but
+// https://code.google.com/p/android/issues/detail?id=216978#c6 is a reason one.
+// The issue is that we need fine-grained control over when to include Gecko's
+// binary libraries into the GeckoView AAR and the Fennec APK, and that's hard
+// to achieve.  In particular:
+//
+// * :app:automation wants :geckoview to not include Gecko binaries (automation
+// * build, before package)
+//
+// * :geckoview:withLibraries wants :geckoview to include Gecko binaries
+// * (automation build, after package)
+//
+// * non-:app:automation wants :geckoview to include Gecko binaries (local
+// * build, always after package)
+//
+// publishNonDefault (see
+// http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Library-Publication)
+// is intended to address this, but doesn't handle our case.  That option always
+// builds *all* configurations, which fails when the required Gecko binaries
+// don't exist (automation build, before package).  So instead, we make both
+// :app and :geckoview both know how to include the Gecko binaries, and use a
+// non-default, non-published :geckoview:withGeckoBinaries configuration to
+// handle automation's needs.  Simple, right?
