[Owncloud] getInternalPath and absolute User Homes

[Arthur Schiwon]

Hi Victor,

OC_User::getHome($uid) is a method provided for user backends to return the 
home folder for the user given. For exmaple, instead of 
/var/www/owncloud/data/USER/ it could be /home/USER/ or 
/mnt/someotherstorage/owncloud/USER 

It needs to be in OC_User as it is a core function. User backends who want to 
implement this functionality need to implement such a method.

Cheers
Arthur
