When overwriting shared files as recipient, the part file is written on
the uploader's storage before overwriting the target file.
If the uploader has no quota left, they should still be able to
overwrite that file with Webdav. To make this work, they need to be able
to write the part file to their own storage first.
As constants not defined within a class cannot be automatically found by the
autoloader moving those constants into a class makes them accessible to
code which uses them.

Fixed the quota storage wrapper to correctly return the quota value when
the free space is not known (which usually happens when the disk_free_space
function is disabled)
This fixes the "used space" to be based on the unencrypted size, not
encrypted size, to be consistent with how quota/space is handled when
encryption is enabled
When calling fopen() on some storage types, these return false instead
of throwing an exception.
This fix makes sure that in case the stream wasn't opened (for example
when a file doesn't exist any more) the stream isn't wrapped.
Also added 'rb' as another case that doesn't need to be wrapped.
Fixes#6832
