py3: bulk replace sys.stdin/out/err by util's Almost all sys.stdin/out/err in hgext/ and mercurial/ are replaced by util's. There are a few exceptions: - lsprof.py and statprof.py are untouched since they are a kind of vendor code and they never import mercurial modules right now. - ui._readline() needs to replace sys.stdin and stdout to pass them to raw_input(). We'll need another workaround here.
