multirepos: Added an admin panel to manage repositories.

* `trac-admin` commands to manage repositories in the database have been moved to `DbRepositoryProvider`.
* Repository syncronization must still be triggered with `trac-admin`.

Part of #8291.

multirepos: Fixed display of repositories with errors in repository index.

multirepos: Migrated the SVN cache metadata caching to new caching infrastructure.

Related to #7723.

0.12dev: Merged [8161] from 0.11-stable, now that #G300 is fixed.

0.11-stable: Backed out [8184] due to #8282. I'll propose a better fix in #5640.

0.12dev: backout r8196 - this change triggered `LazyProxy` instances to be used in contexts where they shouldn't have been.

i18n: `Translations.load` return a `NullTranslations` instance when the catalogs are not available.

This later makes the `add` fail:
{{{
NullTranslations instance has no attribute 'add'
}}}
So better ''not'' consider the translations are active in this condition.

0.11-stable: backported r8194 (support alternate db backend for unit-tests)

0.12dev: merged [8189:8193/sandbox/rework-testing], alternate db backend for unit-tests and Makefile improvements.

rework-testing branch: move the environment from the Makefile to a Makefile.cfg.sample file.

Copy the latter into Makefile.cfg and adapt to your local environment.
In case the Makefile.cfg file is missing, the Makefile should work like before r8189.
