Add keyboard shortcuts inhibitor



This adds a new protocol to let Wayland clients specify that they want
all keyboard events to be sent to the client, regardless of the
compositor own shortcuts.

This protocol can be used for virtual machine and remote connection
viewers which require to pass all keyboard shortcuts to the hosted or
remote system instead of being caught up by the compositor locally.

<description summary="Protocol for inhibiting the compositor keyboard shortcuts">
This protocol specifies a way for a client to request the compositor
to ignore its own keyboard shortcuts for a given seat, so that all
key events from that seat get forwarded to a surface.
Warning! The protocol described in this file is experimental and
backward incompatible changes may be made. Backward compatible
changes may be added together with the corresponding interface
version bump.
Backward incompatible changes are done by bumping the version
number in the protocol and interface names and resetting the
interface version. Once the protocol is to be declared stable,
the 'z' prefix and the version number in the protocol and
interface names are removed and the interface version number is
reset.

<description summary="context object for keyboard shortcuts inhibitor">
A keyboard shortcuts inhibitor instructs the compositor to ignore
its own keyboard shortcuts when the associated surface has keyboard
focus. As a result, when the surface has keyboard focus on the given
seat, it will receive all key events originating from the specified
seat, even those which would normally be caught by the compositor for
its own shortcuts.
The Wayland compositor is however under no obligation to disable
all of its shortcuts, and may keep some special key combo for its own
use, including but not limited to one allowing the user to forcibly
restore normal keyboard events routing in the case of an unwilling
client. The compositor may also use the same key combo to reactivate
an existing shortcut inhibitor that was previously deactivated on
user request.
When the compositor restores its own keyboard shortcuts, an
"inactive" event is emitted to notify the client that the keyboard
shortcuts inhibitor is not effectively active for the surface and
seat any more, and the client should not expect to receive all
keyboard events.
When the keyboard shortcuts inhibitor is inactive, the client has
no way to forcibly reactivate the keyboard shortcuts inhibitor.
The user can chose to re-enable a previously deactivated keyboard
shortcuts inhibitor using any mechanism the compositor may offer,
in which case the compositor will send an "active" event to notify
the client.
If the surface is destroyed, unmapped, or loses the seat's keyboard
focus, the keyboard shortcuts inhibitor becomes irrelevant and the
compositor will restore its own keyboard shortcuts but no "inactive"
event is emitted in this case.

<event name="active">
<description summary="shortcuts are inhibited">
This event indicates that the shortcut inhibitor is active.
The compositor sends this event every time compositor shortcuts
are inhibited on behalf of the surface. When active, the client
may receive input events normally reserved by the compositor
(see zwp_keyboard_shortcuts_inhibitor_v1).
This occurs typically when the initial request "inhibit_shortcuts"
first becomes active or when the user instructs the compositor to
re-enable and existing shortcuts inhibitor using any mechanism
offered by the compositor.
