simplify processor data accounting (add CPUData structure)
remove Process_clone trick

Reduces resulting code size.

disable useless code in release builds such as runtime type-checking on
dynamic data structures and process fields that are not being computed,
faster(?) method for verifying the process owner (still need to ensure
correctness), don't destroy and create process objects for hidden kernel
threads over and over. Phew. I shouldn't be doing all this today, but I
could not resist.

Mark autogen.sh executable in svn.
