bzr fails to handles too many permanent http redirections

[Vincent Ladeuil]

Reported on the mailing list by Matthias Rahlf <email address hidden>

bzr: ERROR: exceptions.NameError: global name 'redirected_url' is not
defined

Traceback (most recent call last):

<cut for brevity>

bzr 0.15.0dev0 on python 2.5.0.final.0 (linux2)
arguments: ['/usr/local/bin/bzr', 'branch',
'http://launchpad.net/products/bzr-gtk']

The bug is trigered by launchpad doing a double permanent redirection:
http://launchpad.net/products/bzr-gtk
=>
https://launchpad.net/products/bzr-gtk/
=>
https://launchpad.net/bzr-gtk/

Fixed but not tests.

The needed infrastructure is in bzr.http.redirection, I'll add the appropriate tests there.

bzr branch http://launchpad.net/products/bzr-gtk now works correctly.

[Vincent Ladeuil (vila)]

Marked critical as many users may want to branch from launchpad.

This does still fail in 0.15rc2 so we should look at merging before the final release.
