* add tests for fail filter
also tests that fail does not block inspectability
* add fail filter
fallback message is a bit clunky,
since you can't invoke a filter without specifying an input.
That is, "{{ fail }}" doesn't work,
so you have to do "{{ None | fail }}"
* document 'fail' filter
* add changelog fragment
* fail filter uses default message on Undefined or emptystring
makes it slightly easier to use the default message:
```diff
- "{{ None | fail }}"
+ "{{ '' | fail }}"
```
and the user sees a slightly more relevant message
if the message itself is undefined:
```diff
- The error was: {{ failmsg | fail }}: 'failmsg' is undefined
+ The error was: {{ failmsg | fail }}: Mandatory variable has not been overridden
```
* rebuild as the builtin `Undefined`
* harmonise `hint` parameter for make_undefined with jinja
* use code block for documentation item
[ref](https://github.com/ansible/ansible/pull/75435#discussion_r707661035)
* rename to `undef` to expose less Python into the Jinja
[ref](https://github.com/ansible/ansible/pull/75435#pullrequestreview-757799031)
* explicitly instantiate undefined value now that it's possible
see I knew we would break something with reflection
* preserve test coverage of undefined variable

##### SUMMARY
When I used this example it complains with:
ERROR! The tasks/main.yml file for role 'myrole' must contain a list of tasks
The error appears to be in 'ansible/roles/myrole/tasks/main.yml': line 2, column 1, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
---
tasks:
^ here
Removing "tasks:" fixes it.

This is a follow-up of previous years' 1a11cec and c8315bf. It deals
with links which at that point presumably either were not present or
did not support https://
