Initial conversion performed using '2to3 -f print .'. Imports added and duplicate parentheses removed manually. Manually converted files, comments and inline code that 2to3 missed. Presubmit disabled due to an unrelated error in find_runtime_symbols/find_runtime_symbols.py. Afterwards ran "git cl format --python" and cherry-picked the formatting changes. There are no intended behavioural changes.
