GXemul Code2

If a device access routine returns having stopped the CPU, then do not cause interrupts/exceptions, but instead return immediately so that we can break out of the dynstrans loop.

Removing "slow_serial_interrupts_hack_for_linux" (-U) command line option, since it is not used for most guest OSes, and occupied a command line option char.

Moving 'arch' from struct machine to struct cpu; in the future, perhaps this would allow a machine to have heterogenous CPU sets (such as the Dreamcast with both SuperH and ARM).

Adding an empty i960 CPU skeleton [again].

More debugmsg:ifying.

Fixing a bug for MIPS R2000/R3000 when writing to coprocessor 0 "entrylo" register (if the lowest 8 bits were 0, the code took the non-R2000/R3000 code path).

Removing the UNSTABLE_DEVEL configure define; it was not used much, and the debugmsg verbosity levels can be used in its place.
