blink: Rename modules/ method to prefix with get when they collide.

      This focuses on modules/ to rename methods that are named foo() and
that return a Foo*, which will have collisions when foo() is renamed
to Foo() in chromium style.

This patch uses the following to do many of the replacements, so it's
a bit on the larger side..

git gs '\b$foo()'|grep '\.\(cpp\|h\|cc\):'|cut -d: -f1|sort|uniq|xargs sed -ie 's/\b$foo()/$getFoo()/g'
