* Don't parse info.xml but reuse already cached app infos - fixes#25603
* Use === in InfoParser. Fixes test
* InfoParser should not depend on UrlGenerator - fixes issue with session being closed too early
This saves more than 20ms (!) on every request, the previous problem was that `\OC_App::registerAutoloading` calls `\OC\AppFramework\App::buildAppNamespace` which parses the appinfo.xml. Since that was also called multiple times (e.g. on cloud.nextcloud.com over 200 times) that had a significant performance impact. Also on simple PROPFIND requests.
https://blackfire.io/profiles/compare/65a53e6e-7f35-4974-b559-4c81abd01c3b/graph shows the difference nicely.
* setupSettings now also triggered on enable
* fixes detection of present admin section or settings in the DB
* add update routine in such cases
* encryption app migrated
* bump version to ensure tables are created
* make updatenotification app use settings api
* change IAdmin::render() to getForm() and change return type from Template to TemplateResponse
* adjust User_LDAP accordingly, as well as built-in forms
* add IDateTimeFormatter to AppFramework/DependencyInjection/DIContainer.php. This is important so that \OC::$server->query() is able to resolve the
constructor parameters. We should ensure that all OCP/* stuff that is available from \OC::$server is available here. Kudos to @LukasReschke
* make sure apps that have settings info in their info.xml are loaded before triggering adding the settings setup method
At the moment we want to hide the help link from the personal sidebar as it contains the original ownCloud documentation.
Once we have our own documentation with our proper branding and so on we can reenable this.
As discussed we move all old style classes (OC_FOO_BAR) to legacy.
Then from there we can evaluate the need to convert them back or if they
can be fully deprecated/deleted.
