Fixes bug introduced by #25965 (commit dd96a2) pointed out in:

  https://github.com/edx/edx-platform/commit/dd96a2#r48570091

The next button redirect at the top of the sequence in Studio's Unit editing view
was not going to the correct location.

This reverts commit 777bb633.

BREAKING CHANGE: Remove WaffleSwitchNamespace, WaffleSwitch, WaffleFlagNamespace,
and WaffleFlag from waffle_utils, in favor of the Legecy* classes
in edx-toggles. Although this is a breaking change, we have
preemptively removed all known uses.

* temp: remove false positives on safe sessions middleware

This is a temporary fix to deal with false positives in the system due
to the masquerading feature.  Long term we may not want to rely on
knowing about how masquerding works in the safe sessions middleware and
instead manage masquerding of the requset user in some other way.

* MST-682 Add external_user_key to the student profile CSV
This is a request from some Masters school partners. They would like to download the student enrolled list with the Masters external_user_key data referenced. This way, the schools can properly match the students enrolled in the course with the students enrolled through Masters enrollment system

We're fixing an error that appears when you click the "edit access"
button on an XBlock in the library page.

Libraries in the "Add library" page shouldn't have the accessibility
config icon. Access settings for libraries are changed at the top, on
Settings > User Access. When clicking the access-button (the cog) on a
Library, an error appears. This is known to happen on koa.master and
open-release/juniper.3.

This happens due to the way XBlocks are rendered; as they get rendered
initially, the previews are unaware of whether they're part of a
library. We can confirm this by refreshing the page, this makes the
button disappear.

This fix removes the cogwheel when the XBlock is part of a library.
This doesn't affect the XBlocks imported to courses because those are
rendered on a Randomized Content XBlock, which does have its access
options.

Merge pull request #23457 from open-craft/agrendalath/bb-2063-fix-marking-blocks-as-completed-on-course-outline-page-upstream

[BB-2063] Calculate completion for custom blocks on the Course Outline page

For now only the discussion blocks were supported. If we had a custom XBlock that specified `completion_mode = XBlockCompletionMode.EXCLUDED`, then it could never be marked as completed on the course outline page, despite being marked as such inside the learning sequence.

This adds support for displaying completion on the course outline page, to remove the discrepancies between this view and the learning sequence. It also simplifies course outline page by reusing existing APIs for determining completion state and finding the "Resume block"'s target.

Pillow was pinned for Python 3.5 support, which we no longer need.

The toggle state report could not be shared with other IDAs. Here we make use
of the newly available report from edx_toggles, and customize it to add data
from WaffleFlagCourseOverrideModel.
