LibreOffice only allows one invocation per user profile.[^1]
The office provider set the user profile to /tmp/owncloud-instanceid and therefore only one invocation per instance is allowed. This was introduced a while ago, yet it's unclear if this was intentionally or just a side effect.[^2]
The limitation on one invocation leads to the situation that the preview generation only works for a couple of files if you upload a whole folder of emf or word files.
This commit removes the limitation by using a new user profile for each preview. That's done by using instance id plus file id as postfix for getTemporaryFolder.
This has some drawbacks:
- Overload protection: If you upload 100 emf files, you may end up with 100 LibreOffice invocations. Though, you can use preview_concurrency_new to limit the number of previews that can be generated concurrently when php-sysvsem is available.
- New profile: I assume it takes a few bits to generate a fresh LibreOffice user profile. It appears that there is no way to ask LibreOffice to not create a profile and just work with the defaults. The profile will be cleaned after use by our temp manager.
- Remove the configuration option preview_office_cl_parameters: This is not strictly necessary yet, but if you set the configuration option, the generated path for the user profile is also missing. The configuration option is not well documented (e.g., it's unclear that the last option needs to be --outdir) and actually, there should be no reason to change it after all.

The new global search UI is new and might be unstable, hence
we are giving users the option to use the old unified search UI, if
the encounter signficant bottlenecks.

doc(auth): Warn about disabled token passwords and LDAP logout
Auth tokens store the user's login password by default. If the password
changes externally (on LDAP), all connected clients stop syncing after 5
minutes max when the password is verified the next time. A web login
revivess those app passwords.
If storing the password is disabled, the tokens continue to work after
password change. But that also means the clients are not logged out the
same way. This can be fine for some setups and problematic for others.

Fix comments in sample config to be correctly marked as verbatim
The comments were not marked as verbatim and thus the Sphinx compiler to generate
the online admin manual interpreted backslashes as special chars. They disappeared
from the output.
By adding ``, it is marked as verbatim and the backslashes are not removed.

config: add a switch to control truncate before update
To avoid extra truncate on non WORM file systems, add a new config
option `localstorage.unlink_on_truncate`, which defaults to false.
The OC\Files\Storage\Local is update to respect that option.
