Change the type of the first argument to the I/O emulation handlers to 'struct vm *'. Previously it used to be a 'void *' but there is no reason to hide the actual type from the handler. Discussed with: tychon MFC after: 1 week

Add emulation of the "outsb" instruction. NetBSD guests use this to write to the UART FIFO. The emulation is constrained in a number of ways: 64-bit only, doesn't check for all exception conditions, limited to i/o ports emulated in userspace. Some of these constraints will be relaxed in followup commits. Requested by: grehan Reviewed by: tychon (partially and a much earlier version)
