Added functions to retrieve set the fs_info structure (i.e. used to get the partition's name); not implemented yet in the internal file systems. Implemented the dir_create_entry_ref() function. Re-ordered some parameters for the fs calls to be more consistent. git-svn-id: file:///srv/svn/repos/haiku/trunk/current@396 a95241bf-73f2-0310-859d-f6bbb57e9c96
