joerg edafc7f53c Implement a few more floppy ioctl commands and IO options, namely:
. FD_CLRERR clears the error counter, thus re-enables kernel error
  printf()s,

. FD_GSTAT obtains the last FDC operation state, if any,

. FDOPT_NOERRLOG (temporarily) turns off kernel printf() floppy
  error logging,

. FDOPT_NOERROR makes the kernel ignore an FDC error, thus can
  enable the transfer of an erroneous sector to the user application

All options are being cleared on (last) close.

Prime consumer of the last features will be fdread(1), to be committed
shortly.

(FD_CLRERR should be wired into fdcontrol(8), but then fdcontrol(8)
needs a major rewrite anyway.)
