GXemul Code2

Implementing rudimentary tx/rx interrupts for clmpcc; OpenBSD/mvme88k can input/output stuff in userland now :)

Interrupt exceptions (in cpu_dyntrans.c) are no longer generated while single-stepping. (It was too annoying.)

FINALLY found the M88K bug I've been hunting: conditional
branches with delay slots did not set the delay target address
correctly in the case the branch was _not_ taken.

Do not do translation read-ahead when using breakpoints.

Using register names in dev_clmpcc, but no actual progress on getting OpenBSD/mvme88k to boot further.

Updating the man page date from November to December 2008.

Applying a patch from Oleksandr Tymoshenko, to make
piix*_ide register writes work:

Implementing the SH4 fipr instruction (vector dot-product).

Implementing the SH4 fsrra instruction, 1/sqrt(x).

Continuing on i80321 registers (mostly dummy).
