MultiRepos: merged [8082] from 0.12dev

0.12dev: ported r8078 and r8080 from 0.11-stable

MultiRepos: Merged [8079] from trunk.

'''For people who have already upgraded their database to version 22 or 23, this requires manual intervention on the database.'''

You have to remove the `cache` table and re-create it by hand:
{{{
DROP TABLE cache;
CREATE TABLE cache ( id text PRIMARY KEY, generation int );
}}}
(for SQLite; or the equivalent for your database)

See #8197.

Fix some long standing issues in the WSGI layer:
- stop handling a request early when the client disconnected (fix #3043)
- don't write to the client if the file descriptor is already closed (fix #1183)

0.12dev: Renamed the `key` column of the `cache` table to `id` for MySQL compatibility, and changed the type of the `generation` column to `int`.

'''For people who have already upgraded their database to version 22, this requires manual intervention on the database.'''

You can either remove the `cache` table and re-create it by hand:
{{{
DROP TABLE cache;
CREATE TABLE cache ( id text PRIMARY KEY, generation int );
}}}
(for SQLite; or the equivalent for your database)

Or you can downgrade the database version, drop the `cache` table, and upgrade again:
{{{
UPDATE system SET value=21 WHERE name='database_version';
DROP TABLE cache;

trac-admin $TRAC_ENV upgrade
}}}

Closes #8197.

!InterWikiMap component was not always registered in change_listeners.

On trunk, this prevented the proper update of the cache. Fixing on 0.11-stable as well, as the component registration issue is certainly the same there.

MultiRepos: small refactoring of the code for template data preparation in the browser.

MultiRepos: enable directory expansion on Repository Index

MultiRepos: more tweaks to the svn hook script, renamed to trac-svn-hook as it can now be called by both the post-commit hook and the post-revprop-change hook.

MultiRepos: the trac-svn-post-commit script now advises to directly put the TRAC_ENV, PATH (+ eventually LD_LIBRARY_PATH) configuration inside (a copy of) the trac-svn-post-commit script.

That way a multi-repository setup is easier to maintain, as there's only one line which has to be added to each repository's hooks/post-commit script, i.e.

{{{
/path/to/trac-svn-post-commit $REPOS $REV
}}}
