Major overhaul for window size handling. This basically switches qemu
over to use geometry hints for the window manager instead of trying to
get the job done with widget resize requests. This allows to specify
better what we need and also avoids window resizes.
FIXME: on gtk2 someone overwrites the geometry hints :(

Currently only evdev keycodes are handled by the gtk-ui. SDL has
code to handle both. This patch adds similar processing so that
both keycode types will be handled via the gtk-ui.

"View->Detach tab" will move to tab to a new window.
Simply closing the window will move it back into a notebook tab.
The label will be permamently stored in VirtualConsole->label,
so it can easily be reused to (re-)label tabs and windows.
Works for vte tabs only for now. pointer/kbd grab code needs
adaptions before we can enable it for gfx tabs too.

Each display gets its own tab. Tab switching continues to work like it
did, just the hotkeys of the vte consoles changes in case a secondary

In general QMP command parameter values are specified by consumers of the
QMP/HMP interface, but in the case of optional parameters these values may
be left uninitialized.
It is considered a bug for code to make use of optional parameters that have
not been flagged as being present by the marshalling code (via corresponding
has_<parameter> parameter), however our marshalling code will still pass
these uninitialized values on to the corresponding QMP function (to then
be ignored). Some compilers (clang in particular) consider this unsafe
however, and generate warnings as a result. As reported by Peter Maydell:
This is something clang's -fsanitize=undefined spotted. The
code generated by qapi-commands.py in qmp-marshal.c for
qmp_marshal_* functions where there are some optional
arguments looks like this:
bool has_force = false;
bool force;
mi = qmp_input_visitor_new_strict(QOBJECT(args));
v = qmp_input_get_visitor(mi);
visit_type_str(v, &device, "device", errp);
visit_start_optional(v, &has_force, "force", errp);
if (has_force) {
visit_type_bool(v, &force, "force", errp);
}
visit_end_optional(v, errp);
qmp_input_visitor_cleanup(mi);
if (error_is_set(errp)) {
goto out;
}
qmp_eject(device, has_force, force, errp);
In the case where has_force is false, we never initialize
force, but then we use it by passing it to qmp_eject.
I imagine we don't then actually use the value, but clang
complains in particular for 'bool' variables because the value
that ends up being loaded from memory for 'force' is not either
0 or 1 (being uninitialized stack contents).
Fix this by initializing all QMP command parameters to {0} in the
marshalling code prior to passing them on to the QMP functions.

Using error_is_set(ERRP) to find out whether a function failed is
either wrong, fragile, or unnecessarily opaque. It's wrong when ERRP
may be null, because errors go undetected when it is. It's fragile
when proving ERRP non-null involves a non-local argument. Else, it's
unnecessarily opaque (see commit 84d18f0).
The error_is_set(errp) in qemu_chr_new_from_opts() is merely fragile,
because the callers never pass a null errp argument.
Make the code more robust and more obviously correct: receive the
error in a local variable, then propagate it through the parameter.

This patch allows to insert and remove sw breakpoints using the QEMU gdbserver
on s390 as well as to interrupt execution on a breakpoint hit when running
with KVM enabled.
Whenever a software breakpoint is inserted, common code calls kvm ioctl
KVM_UPDATE_GUEST_DEBUG. As this method's default on s390 is to return an error
if not implement, the insertion will fail. Therefore, KVM also has to be
updated in order to make use of software breakpoints.

Commit 40f1ee27aa introduced handy helpers for enable_cap calls on

seem to choke on signedness detection in inline created variables:
target-ppc/kvm.c: In function 'kvmppc_booke_watchdog_enable':
target-ppc/kvm.c:1302:21: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits]

target-ppc/kvm.c:1504:21: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits]
However - thanks to Thomas Huth for the suggestion - we can just cast the
offending potentially 0 value to a signed type, making the comparison signed.
