  SVN rev 187544 on 2009-01-21 17:32:26Z by jkim
  
  MFC:    r184976
  
  - Revive fdc(4) per-device flag 0x10, which was removed in r1.284[1].
  - If the flag is set and auto-select fails, assume disk is not present.
  - Set disk empty flag only when the floppy controller reset is needed.
  It fixes regression introduced in r1.311, which prevented it from ignoring
  errors.  Now fdformat(1) and dd(1) with conv=noerror option can continue
  when read/write errors occur as they should.
  - Do not retry disk probing as it is extremely slow and pointless.
  - Move the disk probing code into a separate function.
  - Do not reset disk empty flag if write-protect check fails somehow.
