Mercurial can have bookmarks pointing to "nullid" (the empty root
revision), while Git can not have references to it. When cloning or
fetching from a Mercurial repository that has such a bookmark, the
import failed because git-remote-hg was not be able to create the
corresponding reference.
Warn the user about the invalid reference, and do not advertise these
bookmarks as head refs, but otherwise continue the import. In
particular, we still keep track of the fact that the remote repository
has a bookmark of the given name, in case the user wants to modify that
bookmark.
Also add some test cases for this issue.

A fast-import stream expresses a pathname with funny characters by
quoting them in C style; remote-hg remote helper forgot to unquote
such a path.
* ap/remote-hg-unquote-cquote:
remote-hg: unquote C-style paths when exporting
git-fast-import documentation says that paths can be C-style quoted.
Unfortunately, the current remote-hg helper doesn't unquote quoted
path and pass them as-is to Mercurial when the commit is created.
This results in the following situation:
- clone a mercurial repository with git
- add a file with space in a directory: `>dir/foo\ bar`
- commit that new file, and push the change to mercurial
- the mercurial repository now has a new directory named '"dir',
which contains a file named 'foo bar"'
Use Python str.decode('string-escape') to unquote the string if it
starts and ends with ". It has been tested with quotes, spaces, and
utf-8 encoded file-names.

Keep track of Mercurial revisions as Git notes under the 'refs/notes/hg'
ref. This way, the user can easily see which Mercurial revision
corresponds to certain Git commit.
Unfortunately, there's no way to efficiently update the notes after
doing an export (push), so they'll have to be updated when importing
(fetching).

If we have an old organization (v1.8.3), and want to upgrade to a newer
one (v1.8.4), the user would have to fetch the whole repository, instead
we can just move the repository, so the user would not notice any
difference.
Also, remove other clones, so in time they get set up as shared.

6796d49 (remote-hg: use a shared repository store) introduced a bug by
making the shared repository '.git/hg', which is already used before
that patch, so clones that happened before that patch, fail after that
patch, because there's no shared Mercurial repo.
So, instead of simply checking if the directory exists, let's always try
to create an empty shared repository to ensure it's there. This works
because we don't need the initial clone, if the repository is shared,
pulling from the child updates the parent's storage; it's exactly the
same as cloning, so we can simplify the shared repo setup this way while
at the same time fixing the problem.

The current code fixes the path to make it absolute when cloning, but
doesn't consider tilde expansion, so that scenario fails throwing an
exception because /home/myuser/~/my/repository doesn't exists:
$ git clone hg::~/my/repository && cd repository && git fetch
Expand the tilde when checking if the path is absolute, so that we don't
fix a path that doesn't need to be.

The logic when working with a local repository is totally different from
the one where we work with a remote repository; we need to pull and push

Mercurial always checks out the 'default' branch, so there's no point in
complicating our lives trying to do something fancier, which causes
different behavior depending on whether the repository is local or
remote.
So let's always use 'default' (which we translate to 'master'), unless
we are in hg-git mode, which expects us to use the 'master' bookmark
instead.
Also, update the tests that used to check for different checkout
behaviors to simply check that the refs are there, remove unnecessary
ones, and fix the ones that expect something different.
