commit 5e8fc527dd73f46682283810a01445672e475b80
Author: michaeldo <michaeldo@chromium.org>

Move common functionality of IOSChromeIOThread to ios/components.

Most of this functionality is not reliant on ios/chrome. Moving it to
ios/components allows it to be used by ios/web_view. The existing
unittest is left in place because it relies on the setup that happens in
the IOSChromeUnitTestSuite class.

commit 5a855f2c363b8372560eb21d9d7935cd3b0c5055

Remove share script TODO.

There is no need to try to share this script. This script is not
replicated verbatim as chrome has the ability to click(), focus(), or
submit() with a single helper function.
