David van Moolenbroek 701f2b4dd5 VFS: select(2) fixes ...

- check each file descriptor's open access mode (filp_mode);
- treat an error returned by a character driver as a select error;
- check all filps in each set before finishing select;
- do not copy back file descriptor sets if an error occurred;
- remove the hardcoded list of supported character major devices,
  since all drivers should now be capable of responding properly;
- add tests to test40 and fix its error count aggregation.
