1.0dev: Merged from 0.12-stable.

0.12-stable: Don't store some preferences in the timeline, diff and wiki if they are equal to the default value. This should help limiting the size of the `session_attribute` table.

Closes #10535.

0.12-stable: Use the mode "a+" instead of "r+" to check that the PID file is writable, to avoid failing if the file doesn't exist.

Closes #10566.

1.0dev: Only enable `tracopt.versioncontrol.svn.*` instead of `tracopt.*` for unit and functional tests, to avoid increasing the test run time.

Part of #10712.

1.0dev: Moved the `svn_fs` and `svn_prop` modules to `tracopt.versioncontrol.svn`.

Closes #10712.

1.0dev: add deprecation warning for suggest.js (closes #7355)

1.0dev: make ticket ranges wrap in batch events in the Timeline

Also wrap rendered TicketQuery in grouped compact format.

To make it possible to copy back ticket ranges links as now generated,
and still have them interpreted as the same range in the wiki, we
support ZWSP in the Ranges class.

This closes #10713.

ticket: add helper method `_cc_list`, hiding the use of Chrome

ticket: reformat imports in web_ui.py

1.0dev: Make it easy to revert individual ticket field changes, with a "revert" link next to each change in the preview. This also makes it simpler to resolve ticket edit conflicts.

Closes #7145.
