Make SVM be disabled by default on all CPU models when in KVM mode.
Nested SVM is enabled by default in the KVM kernel module, but it is
probably less stable than nested VMX (which is already disabled by
default).

Add a new compat function, x86_cpu_compat_kvm_no_autodisable(), to keep
compatibility on previous machine-types.

TCG doesn't support VMX, and nested VMX is not enabled by default in the
KVM kernel module.

So, there's no reason to have VMX enabled by default on the core2duo and
coreduo CPU models, today. Even the newer Intel CPU model definitions
don't have it enabled.

In this case, we need machine-type compat code, as people may be running
the older machine-types on hosts that had VMX nesting enabled.

The following CPU features were never supported by neither TCG or KVM,
so they are useless on the CPU model definitions, today:

 * CPUID_DTS (DS)
 * CPUID_HT
 * CPUID_TM
 * CPUID_PBE
 * CPUID_EXT_DTES64
 * CPUID_EXT_DSCPL
 * CPUID_EXT_EST
 * CPUID_EXT_TM2
 * CPUID_EXT_XTPR
 * CPUID_EXT_PDCM
 * CPUID_SVM_LBRV

As using "enforce" mode is the only way to ensure guest ABI doesn't
change when moving to a different host, we should make "enforce" mode
the default or at least encourage management software to always use it.

In turn, to make "enforce" usable, we need CPU models that work without
always requiring some features to be explicitly disabled. This patch
removes the above features from all CPU model definitions.

We won't need any machine-type compat code for those changes, because it
is impossible to have existing VMs with those features enabled.

KVM never supported the CPUID_ACPI flag, so it doesn't make sense to

The motivation here is exactly the same we had for the MONITOR flag

but does include an M profile specific oddity (disabling

on the other hand is getting rapidly more complicated

code out into its own implementation of cpu_exec_interrupt

Passing the CPUARMState around in the decoder is a recipe for
bugs where we accidentally generate code that depends on CPU

and instead use DisasContext as a way to pass around those
bits of CPU state which are known to be safe to use.

In fullscreen mode, we attempt to shrink the menubar to 1 pixel in height,
so it takes up as little room as possible while still allowing us to use
the keyboard shortcuts for its various operations.

However this shrinking is disregarded on gtk3, so the entire menu bar is
visible, which isn't very pleasant. This patch hides the menu bar instead.

The side effect is that the only keyboard shortcuts that will work in this
mode are the ones that we explicitly register on the top level window and
not the menu bar. The previous patches changed the fullscreen and vc
shortcuts to work like that, which I think are the only ones that really
matter in for the fullscreen case.
