It does not make sense that generic repository code contains handling of environment variables, which are specific for the main repository only. Refactor repo_set_gitdir() function to take $GIT_DIR and optionally _all_ other customizable paths. These optional paths can be NULL and will be calculated according to the default directory layout. Note that some dead functions are left behind to reduce diff noise. They will be deleted in the next patch.
