0.12dev: merged r8381 and r8382 from 0.11.6dev

When performing a backup of a PostgreSQL database, the schema parameter to the `-n` option needs to be quoted if it contains uppercase characters.

Patch contributed by bobbysmith007@..., thanks!

Closes #8502.

Fix database initialization for functional enviroments, in case the schema is not already existing.

See #8518 - the change might be enough to fix that issue.

MultiRepos: Renamed `ChangesetMessage` macro to `CommitTicketReference`, and removed the `hide_noref` argument, as it was only intended for the macro to be useful outside of the plugin.

Related to #1507.

0.12dev: Merged [8375] from 0.11-stable.

MultiRepos: More improvements to the commit ticket updater plugin:

* In the ticket comment, wrap the commit message in a `ChangesetMessage` wiki processor call containing the repository name and the revision. This allows extracting the message from the repository and has the following advantages:
- It can be formatted according to the current `[changeset] wiki_format_messages` option.
- It is always up-to-date, even if the message is modified.
- The ticket comment can be hidden if the message is modified and it doesn't reference the ticket anymore.
- As the initial changeset message is contained in the body of the wiki processor call, it is visible in the (plain text) notification e-mail.

* A special value `<ALL>` in `[ticket] commit_ticket_update_commands.refs` will generate a ticket comment for all tickets referenced by the message, even if no command is given.

Closes #1507.
