Update to 0.4.2.

Changes between release 0.4.1 and 0.4.2 include, among other things:

    o)	The NetWinder emulation mode now works well enough to let
	NetBSD/netwinder run from a disk image.

	(NetBSD/netwinder has to be installed manually, though, because
	there is no installation ramdisk kernel. The GXemul documentation
	has an example of how to install NetBSD/netwinder using an emulated
	NetBSD/pmax machine.)

    o)	Algorithmics P5064 emulation works well enough to let NetBSD/algor
	run from a disk image. (Similar to NetBSD/netwinder, it has to
	be installed manually, using another emulated machine.)

    o)	PCI configuration register writes can now be handled, which allows
	NetBSD/Malta (evbmips) 3.0.1 and NetBSD/cobalt 3.0.1 to run from
	PCI IDE harddisk images. (Previously, only NetBSD 2.1 worked for
	the Malta and Cobalt emulation modes.)

    o)	Some performance increases:

	The virtual translation table update routine has been simplified
	to work the same way for 32-bit and 64-bit emulation, and this
	apparently results in a speedup for all 64-bit modes.

	For 32-bit MIPS, some more instruction combinations have been added.
