ui: option to preserve the progress bar

Some interface like the fast-import format of git are meant for pipe
processing. It can be still desirable to have progress bars in this
case, but clearing the bar after each output operation is not desirable.

        The color used is controlled by an optional keyword argument, "label".
        This should be a string containing label names separated by space.
        Label names take the form of "topic.type". For example, ui.debug()
        issues a label of "ui.debug".

        When labeling output for a specific command, a label of
        "cmdname.type" is recommended. For example, status issues
        a label of "status.modified" for modified files.
        '''
        dest = self._fout

                self._buffers[-1].extend(self.label(a, label) for a in args)
            else:
                self._buffers[-1].extend(args)
            return

        # inliend _writenobuf() for speed
        self._progclear()
        msg = b''.join(args)

        # opencode timeblockedsection because this is a critical path
        starttime = util.timer()
        try:

        else:
            self._writenobuf(dest, *args, **opts)

    def _writenobuf(self, dest, *args, **opts):
        # update write() as well if you touch this code
        self._progclear()
        msg = b''.join(args)

        Progress reports via stderr are normally cleared before writing as
        stdout and stderr go to the same terminal. This can be skipped with
        the optional keyword argument "keepprogressbar". The progress bar
        will continue to occupy a partial line on stderr in that case.
        This functionality is intended when Mercurial acts as data source
        in a pipe.
