Move the I/O condition types from `(rnrs conditions)', where they were not exported, to `(rnrs files)', where they are. * module/rnrs/conditions.scm: Remove definition of I/O condition types. * module/rnrs/files.scm: Replace references to I/O condition types inside `(rnrs conditions)' with the actual definitions. * module/rnrs/io/simple.scm: Don't `@@'-reference the I/O condition types, just imported them from `(rnrs files)'.
