Log:
Switch to using 16 bit handles instead of 32 bit handles.
This is a pretty invasive change, but there are three good
reasons to do this:
1. We'll never have > 16 bits of handle.
2. We can (eventually) enable the RIO (Reduced Interrupt Operation)
bits which return multiple completing 16 bit handles in mailbox
registers.
3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec
changed such that at_reserved (which was 32 bits) was split into
two pieces- and one of which was a 16 bit handle id that functions
like the at_rxid for Fibre Channel (a tag for the f/w to correlate
CTIOs with a particular command). Since we had to muck with that
and this changed the whole handler architecture, we might as well...
Propagate new at_handle on through int ct_fwhandle. Follow
implications of changing to 16 bit handles.
These above changes at least get Qlogic 1040 cards working in target
mode again. 1080/12160 cards don't work yet.
In isp.c:
Prepare for doing all loop management in outer layers.
