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.

This makes it less generic and only used for actual file chunking

As discussed we move all old style classes (OC_FOO_BAR) to legacy.
Then from there we can evaluate the need to convert them back or if they
can be fully deprecated/deleted.

This code is not used anymore.

Fixes #22601

Before we did a full test on all chunks to verify if a chunked upload
was completed. This is unneeded since if we are missing one chunk we can
already fail.

Also we look from back to front since it is much more likely that we
find a missing chunk thus can error out early.

This reverts commit 6a1a4880.

using scrutinizer patch

- fixed free space detection based on the already uploaded chunks
- now deleting chunks as soon as it is read out before writing it into
  the part file, which reduces the space needed when assembling part
files
