* fixes #20455

Fix absolute path creation for remote shares with /oc webroot

Fixes #23325

It can happen that a user shares a folder with public upload. And some
time later the admin disables public upload on the server.

To make sure this is handled correctly we need to check the config value
and reduce the permissions.

Fix is kept small to be easy backportable.

Display external storage GUI even if user mounting disabled

Exclude only known failing third-party files

[CI] Installation: Combined database errors

Some typo corrections in occ command output

Don't try to execute a dav syntax test

Fallback for crappy ancient distributions

Add integration tests for sharee endpoint

Error Fixed

combined the database errors

Merged Database Errors

Give swift 15 seconds after startup

add title and color to birthday calendar

handle connection errors as storage not available in smb

This way we can also scan the third-party folder for incompatibilities with a used PHP version. Since there are some polyfills that would otherwise fail I had to exclude them manually here.

Ensure that stored version is at least 1 for cross-storage copy

Check the syntax on travis

Require at least libxml 2.7.0

Specify the target user when unsharing a federated share

In case of a move operation from an unencrypted to an encrypted
storage the old encrypted version would stay with "0" while the
correct value would be "1". Thus we manually set the value to "1"
for those cases.
