sslutil: be less strict about which ciphers are allowed when using --insecure

Python 3.10 restricted which ciphers are enabled by default, leading to
no available ciphers for TLS < 1.2.  When using the --insecure flag we
allow old TLS, so also adjust the cipher list to give connections a
chance to work.

On the server side, also loosen the cipher selection in tests (when
using the devel.serverexactprotocol option).

====================================
Testing head checking code: Case D-7
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category D: remote head is "obs-affected" locally, but result is not part of the push
TestCase 7: single changesets, superseeded multiple time then pruned (on a new changeset unpushed) changeset

This is a partial push variation of B6

.. old-state:
..
.. * 1 changeset branch
..
.. new-state:
..
.. * old branch is rewritten onto another one,
.. * The rewriting it again rewritten on the root
.. * the new version is then pruned.
..
.. expected-result:
..
.. * push allowed
