LibGUI+WindowServer: Use anonymous files for window backing stores :^)
This patch replaces the use of shbufs for GUI::Window backing stores
with the new anonymous files mechanism.
Backing bitmaps are now built on memory allocated with anon_create().
They are passed across the IPC socket as IPC::File. This means that
WindowServer now pledges "recvfd" and graphical clients need to pledge
"sendfd" to work.
To support the cached bitmap swapping optimization on the WindowServer
side, each backing store is assigned an incrementing serial number on
the client side. (This allows us to re-use an already mapped file.)
