[PATCH 0/7] Prepare git-remote-helpers series for hg support

[Sverre Rabbelier <srabbelier@gmail.com>]

This series does not add hg support, but it does do all the
refactoring that is needed to make it possible. With this series
applied actually adding full-fledged hg support is a matter of adding
the git-remote-hg file.
The reason the git-remote-hg file is not included in this series is
that while I have finished support for 'git clone hg::/path/to/hg' as
well as 'git fetch hg::/path/to/hg' and 'git fetch hgremote',
currently it does a full export on each run (that is, incremental
fetch is not supported).
Nevertheless, I think it is vital that this is included in the series
before we do anything serious with it. I hope to have the
git-remote-hg bit done tomorrow before I get on my airplane, but no
promises there.

Junio, I can try to re-roll the entire series after I finish
git-remote-hg, or I can just send it in on top of this series.

Based on abdcdc5c [More fixes to the git-remote-cvs...].

Johannes Schindelin (1):
      Finally make remote helper support useful

Sverre Rabbelier (5):
      .gitignore: add git-remote-cvs
      Add notify and warn to util.py
      Allow both url and foreign vcs in remote config
      When updating refs after a fetch, resolve the symref if set
      Factor ref updating out of fetch_with_import
