Renaming a resource to banned name is allowed

[haribhandari07]

Description

Renaming a file or folder to the banned name for eg; \name is not forbidden

Steps to reproduce:

1. upload a file curl -X PUT -uadmin:admin -k https://localhost:9200/remote.php/webdav/file1.txt -d"123"
2. rename the file curl -X MOVE -uadmin:admin -k https://localhost:9200/remote.php/webdav/file1.txt -H "Destination: https://localhost:9200/remote.php/webdav/\file1.txt" -v
3. list files: curl -X PROPFIND -uadmin:admin -k https://localhost:9200/remote.php/webdav | xmllint --format -

a file with the name <d:href>/remote.php/webdav/%5cfile1.txt</d:href> is listed

It's also possible to upload a file with that name:
curl -X PUT -uadmin:admin -k https://localhost:9200/remote.php/webdav/%5cfile2.txt -d"123"

The same behavior is noticed for the folder.

on EOS storage the renaming does not work, but the return code is 500 and not 400 as it should be

[refs]

confirm it still occurs with the latest master.

Where is a banned name configured?

I think the thought is that filenames with a \ will get us into trouble on windows systems
I've updated the original post to make it easier to reproduce.
also web happily uploads a file with a \ in its name, but it cannot download such a file again

If a \ is a legal character in a files name then the issue needs to be moved to web, if not creating such files need to be prevented
