This patch drops DT_VNC.  The display types are only used to select
select the local display (i.e. curses, sdl, coca, ...).  Remote
displays (for now only vnc, spice will follow) can be enabled
independently.

The OpenIndiana (Solaris) e1000g driver drops frames that are too long
or too short.  It expects to receive frames of at least the Ethernet
minimum size.  ARP requests in particular are small and will be dropped
if they are not padded appropriately, preventing a Solaris VM from
becoming visible on the network.

The signedness of enum types depend on the compiler implementation.
Therefore the check for negative values may or may not be meaningful.

Fix by explicitly casting to a signed integer.

Since the values are also checked earlier against event_names
table, this is an internal error. Change the 'if' to 'assert'.

According to the Book3S spec, the interrupt context starts with an MSR
value that is rather simple. If we leave out the HV case, it's almost
always 0.

To reflect this, let's redesign the way that MSR value gets calculated.
Using this, we also squash the bug where MSR_POW can slip through into
the interrupt handler MSR.

The lwarx and ldarx instructions have a bit to give some hint to the
CPU which is safe to ignore. We currently refuse to accept any instruction
with that bit set, as it used to be declared MBZ.

Let's remove the reserved bit and make the instruction work as expected.
