check if the item source was shared to me to decide if it is a re-share or not. Re-sharing of encrypted files should work now, we might still need to test some corner cases

the owner uid is not interesting. We want to get all users who have access to the given item source, no matter from whom it was shared

remove util::getPaths(), this function was broken and is replaced my util::getAllFiles(). When unsharing a folder only remove the share key for sub files if the user really no longer have access to the file. Can happen that a sub-file/-folder is shared to a group the user is a member of or explicitly once more to the same user

fix sharing of folders. First we need to collect all files. Than we need to find all users with access to the file because this can vary from file to file and than we can encrypt it for all recipients

fix missing user_id on write

fix for trashbin

fixed broken file-info

getUsersSharingFile() no longer needed, use  getSharingUsersArray() instead; fix filterShareReadyUsers() to return the correct results

Session needs filesystem view as parameter; use getSharingUsersArray(), this function also adds the owner to the list

necessary changes in util.php after the changes in \OCP\Share::getUsersSharingFile() (fe58e4b1)

we need to add the owner of the file as parameter in case someone else like the owner edits the file; if $includeOwner is set than add owner also if no other recipient was found. This changes enable all user with write access to the file to edit it and to encrypt it to the right list of users again

rename $shareFilePath to $path to avoid confusions, it is not about paths to share files but about general path to files stored in ownCloud

fix file sharing, sharing files works now; moved the identification of file owner and the owner path in the keymanager functions so that other functions doesn't have to deal with it

remove ToDo, every time the file key gets encrypted new share keys are generated and a new encrypted filekey. We always need to use the latest share-keys and encrypted keyfiles

always save key file, the key doesn't change but the encrypted keyfile change always the same way like the share-keys change
