ui: yield unchanged values in walkconfig

Ever since walkconfig was introduced back in 25e7ea0f2cff, the values
yielded has been mutated by replacing "\n" with "\\n". This makes
walkconfig less useful than it could and there is no other way to
iterate over all config sections.

The third-party reposettings extension used ui.walkconfig but did not
take the replacement into account -- this change will actually fix a
bug in the extension when a value contains a newline.

adjust to non-default HGPORT, e.g. with run-tests.py -j

We cannot use the default commit message if fetching from a local
repo, because the path of the repo will be included in the commit
message, making every commit appear different.
