Message:

Rework the way how open files are passed from parent task to child.

• Instead of passing fdi_node_t's, pass handles directly using the IPC_M_STATE_CHANGE_AUTHORIZE mechanism.
• Remove open_node(), fd_node(), fdi_node_t.
• Replace fopen_node() with fopen_handle().
• Replace fnode() with fhandle().
• The child task does not synchronize with VFS yet.
