Enable ticket notification mails to be properly threaded by adding "Re:" to the subject. Thanks for the patch Tim! Closes #4118.

Ported [4206] to 0.10-stable, follow-up to r4201 (''use repos.authz in web_ui/changeset.py'')

The TracChangeset module shouldn't assume the authorizer is a !SubversionAuthorizer; use the `repos.authz` instead.

This also eliminates the incompatibilities with the changes introduced by r4200 to its `__init__` method.

Ported r4204 to 0.10-stable (fixes #2169)

don't send ticket notification when there were no changes to save (fixes #2169)

More nit-picking for the ITicketGroupStatsProvider related code.

In particular, I've changed the TracIni settings, from:
{{{
[trac]
milestone_stats = ...
roadmap_stats = ...
}}}
to:
{{{
[roadmap]
stats_provider = ...
[milestone]
stats_provider = ...
}}}

Simplified the `milestone_stat_to_hdf` helper function and renamed it `milestone_stats_data`

Ported [4200] to 0.10-stable (''#3996, TracBrowser hanging'')

Follow-up to r3971: a loop was introduced between `get_repository()` and `SubversionAuthorizer()`.
That loop in turn got masked by a "hang" will trying to re-acquire the non-reentrant lock introduced by r3980.

Now we explicitely pass the repository instance to the `SubversionAuthorizer` constructor.
Fixes #3996, a big ''thank you'' to Markus, the.ajarn, sam and simon for helping out on this one!

Use `req` instead of `env` in the `milestone_stat_to_hdf` helper method.
