[master] Remove OCS IDs

While making the AppStore ready for 8.1 I also deleted some dummy entries which means that these IDs do not resolve anymore. We should remove them to prevent errors such as https://github.com/owncloud/core/issues/17307

Revert z-index changes

Fix scanFile signature to avoid boring warning

This reverts commit 4edf388a.

This reverts commit 71e5bc18.

Only do the description kung-fu on strings

Clean up part file only once, not twice on error

Changed broken links to php manual

Catch more error codes thrown by federated shares

Use OCP classes as much as possible in files_external

Most of the time it doesn't make sense to forward Guzzle's

This prevents unpredictable error codes to block access to unrelated
folders needlessly.

[upgrade] add verbosity check and show repair info & steps

[upgrade] show timestamp for output during upgrade

Fix undefined offset

OCS Share API link shares now always have an url

Small perf tweak in strlen loop

Remove unneeded getetag entries in properties table

Move core apps from OC_Log::write to OCP\Util

Move files sharing app (mostly) to OCP\DB

Adding exception handling for ServerNotAvailableException

Do not try clearing locked files in cache folder

Use UTF-8 mode for preg_split and preg_replace

Otherwise a single application with a description containing a non compliant character can break the whole ownCloud appstore. This is for example https://apps.owncloud.com/content/show.php?content=149553
