0.11-stable: Catch errors when writing `trac.ini`, and display a warning. Also, revert all changes to the configuration when `config.save()` fails to avoid inconsistencies between server processes.

Closes #5350.

rework-testing: clear the svn:mergeinfo prop on Makefile.cfg.sample.

rework-testing: get the svn tests to work, using r8222 from trunk.

0.11.5dev: ![[MacroList]] should be more robust when plugins give back a buggy non-unicode description.

Fixes #8286.

0.11.5dev: clarify `[notification] always_notify_updater` doc, as requested in #8287.

0.11.5dev: update INSTALL file
- mention setuptools and easy_install
- mention MySQL
- mention bindings for other databases than SQLite

Closes #8298.

Add svn:keywords on bugzilla2trac.py contrib script, as requested in #8318.

MultiRepos: merged with 0.12dev [T8207:8230/trunk]

The tests using the MySQL backend helped to catch a missing space in a SQL query (`CachedRepository.get_changesets()`). Strangely, the other backends were able to cope with that.

0.11.5dev: backported r8230 - testing TRAC_TEST_TRACD_OPTIONS=--http11 with Python 2.3 is OK.

0.12dev: ported r8228 from rework-testing - testing tracd with TRAC_TEST_TRACD_OPTIONS=--http11, everything is fine ;-)
