Log Message:
py-hg-evolve: update to 11.1.1.

This is a bugfix release. Bugs related to wire protocol and topic
namespaces were fixed: `hg incoming` works correctly again
(https://bz.mercurial-scm.org/show_bug.cgi?id=6856), pushing via
ssh shouldn't produce any errors related to tns_heads method on
the peer.  `hg pick` was made to always use current topic for the
resulting changesets, including when users don't have any set (in
which case the resulting changeset will not have any topic, regardless
of what the original changeset had). Default topic namespace value
(which at first was "default", but in 1.1.0 it was changed to
"none") won't get stored on disk and will actively be removed now
(topic extension will do it for at least a couple of releases) to
avoid any confusion when using different versions of topic extension
on the same repo. There were some improvements in handling topics
and topic namespaces that aren't ASCII-only. The evolve and topic
extensions were also marked as compatible with Mercurial 6.6,
although no code changes were required.
