Some PHPDocs were incorrect, also used this opportunity to replace some deprecated functions.

This is unused legacy code. Let it die with ~~~honor~~ fire.

Fixes https://github.com/owncloud/core/issues/12346

This reverts commit 09fd34ee.

This is not installed by default in all cases and will break the DAV features of ownCloud. Lot's of reports such as https://github.com/owncloud/ios-issues/issues/167#issuecomment-63798507

add postfix

Warning: -convert-to is deprecated.  Use --convert-to instead.
Warning: -outdir is deprecated.  Use --outdir instead.

Remove all ports from the trusted domains

Conflicts:
	lib/private/repair.php
	lib/repair/repairconfig.php

This lead to a lot of confusion in the past and did not really offer any value. Let's remove the port check therefore. (it's anyways not really a part of the domain)

Fixes https://github.com/owncloud/core/issues/12150 and https://github.com/owncloud/core/issues/12123 and also a problem reported by @DeepDiver1975.

Conflicts:
	lib/private/request.php

make sure that we only find the shares from the correct share type if users and groups with the same ID exists

In some cases the 'size' field is not available resulting in some PHP errors such as:

```json
{"reqId":"03548fd9e3d3aca15a5796b3b35d7b9d","remoteAddr":"::1","app":"PHP","message":"Undefined index: size at \/Users\/lreschke\/Programming\/core\/lib\/private\/files\/fileinfo.php#125","level":3,"time":"2014-11-17T21:38:57+00:00"}
```

This can be experienced when creating a new empty file and deleting it right away, then when going to the trash bin this error is thrown.

Fixes #12236

Because we're closing the session now before controllers are executed there are cases where we cannot write the session.

This PR removes phpass and migrates to the new Hasher interface.

Please notice that due to https://github.com/owncloud/core/issues/10671 old hashes are not updated but the hashes are backwards compatible so this shouldn't hurt.
Once the sharing classes have a possibility to update the passwords of single shares those methods should be used within the newHash if block.

Fixes https://github.com/owncloud/core/issues/12188 for AppFramework apps

Check already implemented in core/settings/ajax/changedisplayname.php

The update routine tries to test the database migration before actually performing the update.

However, this will fail hard if the schema has changed (for example an unique key has been added). App developers can convert the DB in preupdate.php, however it is not called before and therefore the update fails.

This actually breaks ownCloud updates from ownCloud 6 to ownCloud 7 when the files_antivirus app is enabled.

Those old classes have now non-static pendants and can be deprecated IMHO.

The permissions are already catched properly on the installation so we just have to check whether the file is readable to prevent fatal errors from happening.

Fixes https://github.com/owncloud/core/issues/12135

Either we throw an exception or we ignore it. But we should certainly not print this to the end-user...
