This patch extends the file-system interface with the ability to monitor changes of files or directories. The new 'File_system::sigh' function can be used to install a signal handler for an open node. The 'ram_fs' server has been enhanced to support the new interface. So any file or directory changes can now be observed by 'ram_fs' clients. Fixes #607
