Always try and show pre rendered preview
Currently if the following situation happens

Server generates preview
Server has command removed which allows a preview to be shown
Client asks for preview, gets a 404 error when preview exists
(Mime checked before preview)

This happens more often with documents, or video as the commands are not
native PHP, they require a binary on the server.

After the fix the following would happen

Server generates preview
Server has command removed which allows a preview to be shown
Client asks for preview, gets preview which has been generated
(Mime checked after preview)

This would also allow offline generation (for example a docker image
containing the extra binaries), allowing a reduction in attack surface
of the instance serving the preview data.

Add occ preview:migrate to migrate previews from the old flat structure to a subfolder structure
* `php occ preview:repair` - a preview migration tool that moves existing previews into the new location introduced with #19214
* moves `appdata_INSTANCEID/previews/FILEID` to `appdata_INSTANCEID/previews/0/5/8/4/c/e/5/FILEID`
* migration tool can be stopped during migration via `CTRL+C` - it then finishes the current folder (with the previews of one file) and stops gracefully
* if a PHP memory limit is set in the `php.ini` then it will stop automatically once it has less than 25 MiB memory left (this is to avoid hard crashes in the middle of a migration)
* the tool can be used during operation - possible drawbacks:
    * there is the chance of a race condition that a new preview is generated in the moment the folder is already migrated away - so the old folder with the newly cached preview is deleted and one cached preview needs to be re-generated
    * there is the chance of a race condition during access of a preview while it is migrated to the other folder - then no preview can be shown and results in a 404 (as of now this is an accepted risk)

Move to subfolders for preview files
Else the number of files can grow very large very quickly in the preview
folder. Esp on large systems.

This generates the md5 of the fileid. And then creates folders of the
first 7 charts. In that folder is then a folder with the fileid. And
inside there are the previews.

Christoph Wurst caff1023ea
Format control structures, classes, methods and function
To continue this formatting madness, here's a tiny patch that adds
unified formatting for control structures like if and loops as well as
classes, their methods and anonymous functions. This basically forces
the constructs to start on the same line. This is not exactly what PSR2
wants, but I think we can have a few exceptions with "our" style. The
starting of braces on the same line is pracrically standard for our
code.

This also removes and empty lines from method/function bodies at the
beginning and end.

optimize batch generation of previews
by allowing the generation of multiple previews at once we save on having to find, open and decode the max-preview for every preview of the same file

the main use case for this is the preview generator app (pr for that comming next)

in my local testing this saves about 25% of time when using the preview generator app

allow keeping multiple preview "versions" of the same file
The main use case here is storage provided versioning where we dont have
separate file ids for all the versions, by allowing a prefix for the
version we can store separate previews for all the versions.

Additionally, by keeping all the version previews in the same folder as the
"normal" previews they will be cleaned up properly when the file is deleted

Only generate previews in powers of 4 and set min
Before we'd round up all preview request to their nearest power of two.
This resulted still in a lot of possible images. Generating a lot of
server load and taking up a lot of space.

This moves it to previews to be powers of 4: 64, 256, 1024 and 4096
Also the first two powers are always skipped (4, 16) as it doesn't make
sense to generate previews for that.

We cache preview pretty agressively and I feel this is a better
tradeoff.
