Support gitlinks in fast-import.
Currently fast-import/export cannot be used for repositories with submodules. This patch extends the relevant programs to make them correctly process gitlinks. Links can be represented by two forms of the Modify command: M 160000 SHA1 some/path which sets the link target explicitly, or M 160000 :mark some/path where the mark refers to a commit. The latter form can be used by importing tools to build all submodules simultaneously in one physical repository, and then simply fetch them apart.
