Update to 0.3.7

User-visible change between release 0.3.6.2 and 0.3.7 include:

    o)  The experimental PowerPC emulation mode is now working well enough
        to allow NetBSD/prep 2.1 to be installed and run inside the emulator.
        It is not 100% stable, and it is not optimized for performance yet,
        but hopefully enough for simple experiments.

    o)  I finally took the time to implement a DEC 21143 NIC; this brings
        network connectivity to NetBSD/cats. (The userland "NAT"-like
        networking layer is still a bit buggy, and does not work with
        everything. However, NetBSD/cats can now be installed via ftp.)

    o)  CD-ROM images can now in some cases be detected as ATAPI CD-ROMs
        instead of IDE harddisks. It works for at least NetBSD, OpenBSD,
        and Linux on CATS, and NetBSD on hpcmips.

Internal (code related) changes include:

    o)  Cleanup of the PCI and ISA bus frameworks; in practice this means
        that more code can be shared between different emulated machine
        models than before, and that adding new machine types will become
        easier.

    o)  Dyntrans updates; 32-bit PowerPC mostly, but also many performance
        related updates for ARM.
