Added argument to getFileInfo() to disable adding the size of
mountpoints to a directory's size.

Fixes #5924

Now removing "/./" and trailing "/." from the paths when normalizing.

Legacy home storage ids with the format "local://path/to/datadir/user1"
are now also wrapped by the HomeStorage.

Conflicts:

This reverts commit 079f918d.

this is needed because there is no possibility to set $defaultInstance to false after filesystem::init

revert changes to fbbc76f2 because master is very unstable right now

Thanks @kabum

$password is not supported

When this is the case only the configured max upload size is taking into account for uploading
