/**
* Upgrade the WikiDB and config settings after installing a new
* PhpWiki upgrade.
* Status: experimental, no queries for verification yet,
* no merge conflict resolution (patch?), just overwrite.
*
* Installation on an existing PhpWiki database needs some
* additional worksteps. Each step will require multiple pages.
*
* This is the plan:
* 1. Check for new or changed database schema and update it
* according to some predefined upgrade tables. (medium, complete)
* 2. Check for new or changed (localized) pgsrc/ pages and ask
* for upgrading these. Check timestamps, upgrade silently or
* show diffs if existing. Overwrite or merge (easy, complete)
* 3. Check for new or changed or deprecated index.php/config.ini settings
* and help in upgrading these. (hard)
* 3a Convert old-style index.php into config/config.ini. (easy)
* 4. Check for changed plugin invocation arguments. (hard)
* 5. Check for changed theme variables. (hard)
* 6. Convert the single-request upgrade to a class-based multi-page
* version. (hard)
* Done: overwrite=1 link on edit conflicts at first occurence "Overwrite all".
