Also depend on gitdb2 to regain control and allow
improvements.

Just to allow uploading a more recent one, that ideally
works now.

+ git-daemon:
  + Use git-daemon PORT above 10k; on Windows all below need Admin rights.
  + Used relative daemon-paths with `--base-pth`.
  + Simplify git-daemon start/stop/ex-hanlding.
  +FIXED git-daemon  @with_rw_and_rw_remote_repo():
  + "Polish" most remote & config urls, converting \-->/.
  + test_base.test_with_rw_remote_and_rw_repo() PASS.
+ Remote: 
  + test_remote: apply polish-urls on `_do_test_fetch()` checking function.
  + test_remote.test_base() now freezes on Windows! (so still hidden win_err).
pump fetch-infos instead of GIL-reading stderr.
  + Push-cmd also keep (and optionally raise) any error messages.
+ `cmd.handle_process_output()` accepts null-finalizer, to pump completely
stderr before raising any errors.
+ test: Enable `TestGit.test_environment()` on Windows (to checks stderr
consumption).
+ util: delete unused `absolute_project_path()`.
+ Control separately *freezing* TCs on Windows with `git.util.HIDE_WINDOWS_FREEZE_ERRORS` flag.

+ Ignore `with_extended_output` arg when reaising the exception, keep
its behavior when `status==0`.

+ Bug discovered after enabling TC in prev commit and rework of fetch.
+ remote_tc: unitestize assertions.
+ util: DEL unused `_mktemp()`.

+ `handle_process_output()` accepts null-finalizer, to pump completely
stderr before raising any errors.
+ test: Enable `TestGit.test_environment()` on Windows (to checks stderr
consumption).

+ cmd: use DEVNULL for non PIPEs; no open-file.
+ TCs: some unitestize-assertions on base & remote TCs.
