MINGW, gitpython-developers#525: FIX remote urls in config-files

+ Parse most remote & config-urls \-->/.
+ Used relative daemon-paths.
+ Use git-daemon PORT above 10k; on Windows all below need Admin rights.
+FIXED git-daemon  @with_rw_and_rw_remote_repo():
  + test_base.test_with_rw_remote_and_rw_repo() PASS.
  + test_remote.test_base() now freezes! (so still hidden win_err)

+ repo_test: minor finally delete test-repos created inside this repo.
+ util: delete unused `absolute_project_path()`.
