wireproto: make iterbatcher behave streamily over http(s)

Unfortunately, the ssh and http implementations are slightly different
due to differences in their _callstream implementations, which
prevents ssh from behaving streamily. We should probably introduce a
new batch command that can stream results over ssh at some point in
the near future.

The streamy behavior of batch over http(s) is an enormous win for
remotefilelog over http: in my testing, it's saving about 40% on file
fetches with a cold cache against a server on localhost.

        if err.errno != errno.EINVAL:
            raise
        print f, 'not a symlink'
