stream-clone: add a explicit test for format change during stream clone

They are different kind of requirements, the one which impact the data storage
and are relevant to the files being streamed and the one which does not. For
example some requirements are only relevant to the working copy, like sparse, or
dirstate-v2.

Since they are irrelevant to the content being streamed, they do not prevent the
receiving side to use streaming clone and mercurial skip adverting them over
the wire and, ideally, within the bundle.

In addition, this let the client decide to use whichever format it desire for
the part that does not affect the store itself. So the configuration related to
these format are used as normal when doing a streaming clone.

In practice, the feature was not really tested and is badly broken with bundle-2,
since the requirements are not filtered out from the stream bundle.

So we start with adding simple tests as a good base before the fix and adjust
the feature.

This file contains tests case that deal with format change accross stream clone

#require serve no-reposimplestore no-chg

#testcases stream-legacy

(the #stream-bundle2 variant is actually buggy for the moment)

#if stream-legacy
  $ cat << EOF >> $HGRCPATH

  > bundle2.stream = no

Cloning from a share
--------------------

We should be able to clone from a "share" repository, it will use the source store for streaming.

The resulting clone should not use share.

  $ rm hg-*.pid errors-*.txt
  $ hg share --config extensions.share= server server-share -U
  $ hg -R server-share serve -p $HGPORT -d --pid-file=hg-1.pid --error errors-1.txt
  $ cat hg-1.pid > $DAEMON_PIDS
