[PATCHv2,00/37] SCSI result handling cleanup, part 1

Hi all,

this is the first part of an attempt to clean up SCSI result handling.
The patchset primarily cleans up various drivers by fixing up
whitespaces or move to standard definitions.
It also fixes some minor issues in some drivers which set the
wrong result values.
And, of course, another attempt to kill the gdth driver

I have a larger patchset based on this one to update the SCSI result
handling for all drivers, but decided to split things in two to not
overload reviewers

As usual, comments and reviews are welcome.

Changes to v1:
- Add reviews from Christoph
- Included review from Finn Thain
- Add set_status_byte() helper
- Add cleanup for dc395c
- Add additional patch for using SAM status values instead
  of the shifted linux versions
