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.

Ported [4196] to 0.10-stable (''#1816, / in milestone names'')

Started [milestone:0.10.2]dev

Support "/" in Milestone names. There's no need for replacing '/' by '%2F', I checked that with Apache as well. Fixes #1816.
