py3: use io.BytesIO directly

Previously, pycompat.bytesio and pycompat.stringio referred to
io.BytesIO. And util.bytesio and util.stringio aliased the pycompat
symbols.

This commit switches everything to use io.BytesIO directly. util.bytesio
and util.stringio still exist to provide backwards compatibility, as
they were the preferred symbols.

Check if ":hg:`help TOPIC`" is valid:
(use "xargs -n1 -t" to see which help commands are executed)
