Hi all,

this series removes the BLK_EH_HANDLED return value, and instead places
responsibility of timed out commands entirely on the drivers.  Except
for some odd layering vilations in libiscsi this actually is
surprisingly simple.   Some of the grunt work here is from Keith and
Bart, just repackaged up

Survives my basic smoke testing, including timeout triggering with
null_blk and SCSI. I have applied this, it's much cleaner and simpler.
And we shrink the request a lot, which is great. Note I applied a
followup patch that kills two holes in struct request, and I fixed
a trailing whitespace in patch #3.
