TracRevisionLog: merged first part of changes from 0.11.6dev to trunk.

0.11-stable: Fixed parent directory link in log view. Related to #8349.

TracRevisionLog: in the template, refactor check for separator row.

TracRevisionLog: test CHANGESET_VIEW permission in "verbose" mode as well.

TracRevisionLog: in "verbose" mode, don't show changeset messages for separator entries.

Test infrastructure: fix initial retrieval of a db connexion, right after the creation of the tables.

Doing a shutdown here flushes all the connections from the pool and therefore the next attempt to get a connection will get a new one. Only then apparently will the connection be aware of the newly created tables (remember that `init_db` can't use the connection from the pool, as it's not aware of the pool).

Should fix #8518.

TracRevisionLog: return `limit` entries for the RSS and Changelog format.

Closes #6595.

TracRevisionLog: propagate `revs` parameter to the alternate format links.

TracRevisionLog: improve support for discontinous ranges
- propagate revranges when changing the log options
- the ''Previous revisions'' links to the remaining revisions from the range

Part of #8349.

TracRevisionLog: show ''From r...'' and ''To r...'' tooltips for the Diff radiobuttons.

This is hopefully enough for #4083.
