MultiRepos: merge r7081 from trunk, taking care of moving first the previous upgrade db22.py to db23.py.

'''An environment upgrade is needed.'''

For users that were already using the new cached repositories, the upgrade is needed and automated as well.

TracMercurial for 0.11: python 2.3 compatibility fix. Closes #8195.

0.12dev: Refactored various in-process caches into a `CacheManager` component as described in [wiki:TracDev/Proposals/CacheInvalidation].

'''This changeset increments the `db_version` to 22 and therefore requires an environment upgrade.'''

MultiRepos: new command `trac-admin <env> changeset added|modified`, to be used in hooks.

This replaces the `trac-admin <env> repository notify changeset_added|changeset_removed` command.

Patch by rblank (#7723).
Review and trac-svn-post-commit-hook adaptations by me.
