New sequencer assembler for the aic7xxx adapters. This assembler performs some amount of register type checking, allows bit manipulation of symbolic constants, and generates "patch tables" for conditionalized downloading of portions of the program. This makes it easier to take full advantage of the different features of the aic7xxx cards without imposing run time penalies or being bound to the small memory footprints of the low end cards for features like target mode. aic7xxx.reg: New, assembler parsed, register definitions fo the aic7xxx cards. This was done primarily in anticipation of 7810 support which will have a different register layout, but should be able to use the same assembler. The kernel aic7xxx driver consumes a generated file in the compile directory to get the definitions of the register locations. aic7xxx.seq: Convert to the slighly different syntax of the new assembler. Conditionalize SCB_PAGING, ultra, and twin features which shaves quite a bit of space once the program is downloaded. Add code to leave the selection hardware enabled during reconnects that win bus arbitration. This ensures that we will rearbitrate as soon as the bus goes free instead of delaying for a bit. When we expect the bus to go free, perform all of the cleanup associated with that event "up front" and enter a loop awaiting bus free. If we see a REQ first, complain, but attempt to continue. This will hopefully address, or at least help diagnose, the "target didn't send identify" messages that have been reported. Spelling corrections obtained from NetBSD.
