Reland of Creating libwebrtc bundle jar (patchset #1 id:1 of https://codereview.webrtc.org/2640023010/ )

Reason for revert:
It seems that we cannot skip the generation of "//webrtc/base/base_java" in chromium without some refactoring because it is included as a dependency in some places.

lgtm but ideally we'd get rid of Chromium building the base_java since it's not
used. Can you file a tracking bug for cleaning that up?

[sakal, 2017-01-23 09:22:16]

still lgtm
