Revert 93223 - Reland http://codereview.chromium.org/7452002/

Update chromoting input events. (Clang caught this. Thanks, Clang!)

Note I'm leaving in temporary backwards-compatibility.

brettw, just need a rubber-stamp. This is the same as the last CL. awong/garykac/sergeyu, looking for someone on chromoting team to glance at my changes and make sure I didn't do anything you don't like. This is a high priority for 14, so please look if you can.

BUG=None
TEST=ppapi tests
