[PATCH v7 01/10] t5601: remove clear_ssh, refactor setup_ssh_wrapper

[Torsten Bögershausen]

Commit 8d3d28f5 added test cases for URLs which should be ssh.
Remove the function clear_ssh, use test_when_finished to clean up.

Introduce the function setup_ssh_wrapper, which could be factored
out together with expect_ssh.

Tighten one test and use "foo:bar" instead of "./foo:bar",

Comments to V6:
Code from Johannes Sixt is part of the series, original found here:
 http://permalink.gmane.org/gmane.comp.version-control.git/237339
 http://permalink.gmane.org/gmane.comp.version-control.git/237338

Changes since V6:
- git fetch-pack --diag-url uses stdout instead of stderr
- cleanup in the test scripts
- Removed [PATCH v6 07/10] connect.c: Corner case for IPv6
- Added missing sign-off
- Try to explain better why windows supports file://C:/repo
  (Actually we should support file:///C:/repo, but we don't
- Other remarks from code review, did I miss any ?

I'm not sure about 10/10, 2 cleanups which I didn't manage
to find a  better place to be.
However, I want to concentrate on 1..9, so that 10/10 can be dropped.

And a question:
Can we replace tb/clone-ssh-with-colon-for-port with this stuff ?
If we are OK with part 1..4, I don't need to send them again.
