Work around Python 2.7 urllib2 bug

If the remote is using authenticated HTTP, but does not have
$GIT_URL/clone.bundle files in each repository, an initial sync
would fail around 8 projects in due to the library not resetting
the number of failures after getting a 404.

Work around this by updating the retry counter ourselves.

The urllib2 library is also not thread-safe. Make it somewhat
safer by wrapping the critical section with a lock.
