Passing the CPUARMState around in the decoder is a recipe for
bugs where we accidentally generate code that depends on CPU
state which isn't reflected in the TB flags. Stop doing this
and instead use DisasContext as a way to pass around those
bits of CPU state which are known to be safe to use.
This commit simply removes initial "CPUARMState *env" parameters
from various function definitions, and removes the initial "env"
argument from the places where those functions are called.

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.

On gtk < 3.8, this has the unfortunate side effect of no longer listing

it won't forcibly disable the feature for all CPU models (i.e. add it to
kvm_default_unset_features), but it will instead turn off the KVM
auto-enabling of the feature (i.e. remove it from kvm_default_features),
meaning the feature may still be enabled by default in some CPU models).
