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.
