[PATCH wayland 5/8 v2] protocol: Add minimize/maximize protocol.

[Scott Moreau]

In order for clients to notify the compositor that they wish to be minimized, a
minimize request is needed. This can be used to minimize the surface when a
user clicks the clients minimize button.

The compositor needs a way to tell clients to maximize and unmaximize their
surfaces. The desktop shell client can ask the compositor that a surface be
sent an (un)maximize event, in response to a panel button for example.

The compositor can minimize and unminimize surfaces but clients can only
request their surface be minimized. The client doesn't need to be involved
in a minimize action, unlike (un)maximize, it only needs a way to track its
minimize state and request to be minimized. This patch adds minimize and
unminimize protocol events for this purpose.
