This patch fixes a microcode lockup in my CD-ROM adapters when a blank CD
is inserted. However, do not try to burn CDs yet! I'm pretty sure that
trying it will end in coasters.
- Fix a few cases where we were unable to resynchronize with replies
for previous commands. The main thing is to keep reading replies
in case of a stall. This is done with the new state CLRRS.
- Since I am forgetting the basic state machine already, document it.
- Move counter increments in the looping path in its own function.
- Fix a harmless buglet in case CSW read fails to submit: do not
override state.
- Implement the Alan Stern's idea for adaptive signature checking.
