The first patch set is this previously committed CL:
https://codereview.chromium.org/16494002/ that got reverted. 

The second patch set is what's actually new. Basically I've encountered a cpp
linking error with some of the callbacks in custom function versions when
building Dartium. I'll reapply those specific changes once I get a chance to
talk to Vijay or someone with more experience with Dartium itself. Thanks!

File tools/dom/scripts/htmlrenamer.py (right):

https://codereview.chromium.org/18577002/diff/1/tools/dom/scripts/htmlrenamer...
tools/dom/scripts/htmlrenamer.py:362: 'FormData.append(DOMString name, Blob
value, DOMString filename)':
also removed due to dartium error. (see below)

https://codereview.chromium.org/18577002/diff/1/tools/dom/scripts/htmlrenamer...
tools/dom/scripts/htmlrenamer.py:412: 'WebSocket.send(ArrayBuffer data)':
'sendByteBuffer',

these renames were removed to avoid a dartium error. I'll add them back in once
I get a chance to talk with those with more dartium expertise (everyone's on
vacation right now!)
