sigreturn() and ptrace() security violations will now trap. Deal with those

traps by looking at the instruction stream and the stack to see if it looks
like we're returning to user mode, and if so pop to the hooks in locore.s.
This will fail in the case where a pop %ds or pop %es faults when returning
from a fast interrupt, but this should not be possible.

Sparc disassembler from David Miller.

Heavily munged by me to:
- reduce table size significantly.
- follow various opcode tables in the Sparc Architecture Manual (V9)
more closely.
- recognise V8 priviliged instructions.
- fit the DDB interface.
- fix many typos.
Todo:
- get a number of FP ops right (unimportant until V9 is here).
- opcode aliases (`mov',`cmp',`set') for simple instructions.
- better template matching; current method is sloppy and is prone to spurious
matches.
