Changed an unused field of struct stat (st_rdev) to st_type, so that we

can use this structure to call fstat() on attributes and indices. Added more functions to the file system interface (attributes, and indices). Added header fs_attr.h, and fs_index.h. git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1158 a95241bf-73f2-0310-859d-f6bbb57e9c96
