[PATCH wayland v3] protocol: Add minimize/maximize protocol

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 a minimize button for example.
The compositor needs a way to tell clients to maximize and unmaximize their
surfaces. The desktop shell client can ask the compositor to send a surface
an (un)maximize event, in response to a panel button for example.
The compositor can minimize and unminimize surfaces but clients can only
request that its surface is 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.
Further, the term minimize is relatively subjective and defined by the
implementation. Clients should not expect that minimized means the surface
will be invisable to the user. There are several use cases where displaying
minimized surfaces will be useful. Clients might want to change input handling
or pause when minimized but nothing should change with regards to submitting
surface buffer updates.
