In certain cases changeLock to EXCLUSIVE fails
and throws LockedException. This leaves the
file locked as SHARED in file_put_contents,
which prevents retrying (because on second
call file_put_contents takes another SHARED
lock on the same file, and changeLock doesn't
allow more than a single SHARED lock to promote
to EXCLUSIVE).
To avoid this case, we catch the LockedException
and unlock before re-throwing.

As per https://docs.oracle.com/cd/B19306_01/server.102/b14200/functions060.htm
Oracle uses the first value to cast the rest or the values.
So when the first value is a plain int, instead of doing the math,
it will cast the expression to int and continue with a potential 0.

In the 99% case the bucket is just always there. And if it is not the
read/write will fail hard anyways. Esp on big instances the Objectstore
is not always fast and this can save a few hundered ms of each request
that acess the objectstore.
In short it is adding
'verify_bucket_exists' => false

* removes the ability for users to import their own certificates (for external storage)
* reliably returns the same certificate bundles system wide (and not depending on the user context and available sessions)
The user specific certificates were broken in some cases anyways, as they are only loaded if the specific user is logged in and thus causing unexpected behavior for background jobs and other non-user triggered code paths.

since `json_encode` returns `false` if it's input isn't utf8, all non utf8 paths passed to normalizePath will currently return the same cached result.
Fixing this makes working with non utf8 storages a *little* bit more possible for apps

Currently the "add new files during scanning" call stack is smaller than
the "remove deleted files during scanning" call stack. This can lead to
the scanner adding folders in the folder tree that are to deep to be
removed.
This changes the `removeChildren` logic to be non recursive so there is
no limit to the depth of the folder tree during removal

Fixes#16876
Before we'd just fetch everything from all storages we'd have access to.
Then we'd sort. And filter in php. Now this of course is tricky if a
user shared just a file with you and then has a ton of activity.
Now we try to contruct the prefix path. So that the filtering can happen
right away in the databae.
Now this will make the DB more busy. But it should help overall as in
most cases less queries are needed then etc.

having the "cache rename" after the "storage move" caused the target
to get the fileid from the source file, without taking care that the object
is stored under the original file id.
By doing the "cache rename" first, we trigger the "update existing file"
logic while moving the file to the object store and the object gets stored for the
correct file id

"Exception: substr() expects parameter 3 to be int, bool given" can occur on Line 378 $mimePart = substr($icon, 0, strpos($icon, '-'));
This happens, when '-' is not found and strpos returns false instead of an int.
When this occurs, e.g., Activity hangs.

Right now if you want to get events via the Node API you have to have a
real instance of the Root. Which in turns sets up the whole FS.
We should make sure this is done lazy. Else enabling the preview
generator for example makes you setup the whole FS on each and every
authenticated call.

Currently you need to use `opendir` and then call `getMetadata` for
every file, which adds overhead because most storage backends already
get the metadata when doing the `opendir`.
While storagebackends can (and do) use caching to relief this problem,
this adds cache invalidation dificulties and only a limited number of
items are generally cached (to prevent memory usage exploding when
scanning large storages)
With this new methods storage backends can use the child metadata they
got from listing the folder to return metadata without having to keep
seperate caches.
