This is another step needed to reduce the size of the gigantic
AbuseFilter and AbuseFilterHooks classes. It also makes many methods
non-static, for more testability.
Note, this layout is still not final. We should somehow merge the
functionality of VariableGenerator and AFComputedVariable, for which
I already have plans.

-new_html: also strip the "Transclusion limit" comment if present, and
anyway take it into account (as well as a "</div>"), which right now
prevent the PP limit report from being stripped as well.
-new_text: trim extra whitespace on the right, which is created when
stripping the aforementioned comments.
Also simplify the test for getEditVars, make it not blindly copy what
AFComputedVariable does.
Extra: kill a temporary variable.
These changes are partly taken from
I96785c6c5fdf381c21d5f8930ee12e706abb7f3f.

Some of these are transformed into real unit tests, while the
AbuseFilterSaveTest class is refactored to avoid using the DB and to use
a lot more of mocks and DI.
