I don't know if this belongs here. You have to implement RequestAutocomplete in
browser.cc because it's the WebContentsDelegate. For now that's the end of the
line.

This does belong here.  We shouldn't need to touch browser.cc.

In an ideal world, though, the AutofillManager should be split up into multiple
classes, with IPC message handling probably being handled by a different class
from the one that actually fills out the forms.

 
   // Fills |host| with the RenderViewHost for this tab.
   // Returns false if Autofill is disabled or if the host is unavailable.
