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.

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.

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

Fixes#17828
* Modified the preview provider to provider smaller fonts for the
previes (so it is not so screaming)

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

the main difference is passing the `File` object to the provider
instead of a `View` + path
Old providers will still continue to work as before

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.

To allow us to create previews of files stored in appdata we need to
construct the view differently.

Else if a preview provider is registerd but not available (for example
missing support in some external lib). It will do 💥. This way the
providers can at least do the sanity checks required.

Exporting all pages of a document to a PDF is a waste of time. All we
need is a thumbnail of the first page anyway. Plus, reading that PDF
(even just the first page of it) into imagick is presumably much
slower than reading a simple PNG.

Fixes#9469
When a version of a file is restored the previews are no longer valid.
Thus we should remove them so they are regenerated.

This code had the potential to time out. If a huge folder with pictures
for example was deleted then this could easily grow the number of files
to clean with a factor 5 (or more).
Now the previews just get cleaned up in the background. Which is good
enough for the 99% case
As a bonus this now also keeps the previews when in the trashbin so you
don't have a spiking server load when a user opens the trashbin view.
