Report listed in the ''Available Reports'' report where not checked for REPORT_VIEW fine grained permissions.

Thanks to Dave Gynn for the (bug) report and the initial patch.

Fix the call to `extract_link` in !InterTrac module, which was using the pre-context-refactoring API. Closes #6329.

Timeline refatoring: `changeset_collapse_events` now defaults to `false`.

Fix range order and log link which are generated when this feature is activated.

Timeline refactoring: clean-up the API changes that were introduced during 0.11dev.

The main idea of the original refactoring has been kept: don't render the events directly when generating them, but defer this last step when the event is actually processed within the template.

But instead of requiring a intermediate `TimelineEvent` object, we now rely on a `render_timeline_event` method of the `ITimelineEventProvider` to do the job. The event itself is still a tuple, but of different arity than the one of 0.10, so that we can easily make the difference and keep backward compatibility. The new tuple enable the components to add an arbitrary amount of "private" data to the tuple, for the rendering needs

timeline-refactoring: start new branch for cleaning-up the trac.timeline API changes that occurred during 0.11dev

Merged the [source:sandbox/context-refactoring@... context-refactoring] branch into trunk.

context-refactoring: merging [6135], [6136] and [6137] from trunk

Expand the range of valid InterTrac links by being less strict when interpreting the links on the remote side:
* Use `trac:wiki` or `[trac:wiki]` for linking to the Wiki module
* Use `[trac:]` for linking to the toplevel (#4314)
(replace `trac` by any valid intertrac prefix)

Fixes #5968

Make the error.html template more useful when Javascript is not enabled.

The default view is the plain text view, and only when Javascript is available does the interactive view and the toggle button get shown.
