error:
Overhaul our message printing: - provide a consistent way to print messages: - filesystem corruption should be reported via adfs_error() - everything else should use adfs_msg() - clean up the error message printing when mounting a filesystem - fix the messages printed by the big directory format code to only use adfs_error() when there is filesystem corruption, otherwise use adfs_msg().
