D6843: ui: option to preserve the progress bar

  The goal here is to allow something like "hg fast-export | git fast-import" to show a proper progress bar.
  At the moment every write via ui.write and friends will hide the progress bar and re-enable it, even when stdout doesn't affect the terminal state. This would also make sense for operations like "hg diff", e.g. when writing a large/complicated diff to a file.
