encoding: add fast path of from/toutf8b() for ASCII strings

See the previous patch for why.

The added test seems not making much sense because ASCII strings should
never contain "\xed" and be valid UTF-8.

====================================
Testing head checking code: Case A-1
====================================

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 A: simple case involving a branch being superceeded by another.
TestCase 1: single-changeset branch

.. old-state:
..
.. * 1 changeset branch
..
.. new-state:

.. * 1 changeset branch succeeding to A
