[PATCH v4 00/13] New remote-hg helper

Hi,

I've ported the tests from hg-git and made sure that the output from remote-hg matches the output of hg-git. With these extensive tests I would consider this one ready for wide use. Not only do the tests pass, I've compared the generated repos of a few projects, and the SHA-1's are exactly the same :)

This remote-hg has advantages other tools don't have:

 * Uses transport-helper (git clone hg::path)
 * The code is small
 * The code is simple
 * No external dependencies (other than mercurial)
 * It's easy to install (put into your path)
 * Has extensive tests
 * Active development
 * Has compatibility with hg-git
 * The required patches are available
 * No changes necesary to git core

One important alternative is the one written by Sverre Rabbelier that is now maintained and distributed in msysgit. It's hard to evaluate this option as there isn't a branch specific to this remote helper so it would be possible to evaluate the necessary patches.

Changes since v3:

 * New extensive tests
 * Add compatibility mode with hg-git
 * Added support for boomkars
 * Add mercurial information to the git msg (branch, renames, extra, etc.)
 * Properly handle HEAD
 * Fix author/committer information
 * Implement 'done' feature for error handling
 * Restore hg user properly
 * Set file correct modes
 * Match hg merge behavior
 * Prefix hg branches
 * Encoding fixes
 * Stricter parser
 * Support for 'reset' command
 * Fix support for URL pushing (unaliased)

Changes since v2:

 * Added support for pushing
 * Tests copied from original remote-hg
 * Custom default -> master renames removed
 * Code reorganized

Changes since v1:

 * Improved documentation
 * Use more common 'python' binary
 * Warn, don't barf when a branch has multiple heads
 * Fixed marks to fetch after cloned
 * Support for cloning/pulling remote repositories
 * Use a more appropriate internal directory (e.g. .git/hg/origin)
 * Fixes for python3
