Since 'get_repo_dict' does much more than just querying available
repositories, this patch makes it private. The same data is now
available via the 'repo_dict' property. This also means that
'get_repos' is now faster, because it accesses cached data, instead of
calling 'get_repo_dict' that generates this data.
This patch also allows 'get_repos' and 'repo_dict' to be used even in the
'Repo' class. 'get_repo_dict' creates new 'Repo' instances and thus
invalidates the current instance.
This patch is in preparation of the 'patch support'-feature, that
depends on this patch.
