extensions: avoid enabling evolve for unrelated repositories (issue6057)
The support for the `experimental.evolve` config have been there forever. So we
can stop using the global variable. This help avoiding evolve to enable itself
of repository that did not explicitly activated it. For example, this is useful
for hgwebdir.
Before this change, evolution feature had to be explicitly disabled or enabled
in every single repository.
============================
Testing extensions isolation
============================
In this test case, we check that a repository using the extensions can co-exist
with a repository not using the extension.

Setup
=====
Create repo
$ hg init repo-evo
$ cat > repo-evo/.hg/hgrc << EOF
> [extensions]
> evolve=
> EOF
$ hg init repo-topic
$ cat > repo-topic/.hg/hgrc << EOF
> [extensions]
> topic=
> EOF
$ hg init repo-both
$ cat > repo-both/.hg/hgrc << EOF
> [extensions]
> evolve=
> topic=
> EOF
$ hg init repo-no-ext
check setup
$ hg -R repo-evo help -e evolve | head -n 1
warning: --repository ignored
evolve extension - extends Mercurial feature related to Changeset Evolution
$ hg -R repo-both help -e evolve | head -n 1

$ hg -R repo-no-ext help -e topic

start hgweb dir for all repo
$ cat > hgweb.conf << EOF

Test isolation
--------------
As of 4.9 (and previous version). It seems like extensions are displayed as
enabled even for repository where they are not supposed to be. See the output
tagged `no-false`.
(however, topic and evolve are not supposed to affect other repository as shown
in the rest of this test).

make sure repos don't affect each other (and check both ways)
