This is the direction I wanna take with all interfaces: Clearly
separate interface (aka version information and function pointers)
and state information. SpiceKbdInterface defines the interface,
SpiceKbdInstance maintains per-instance state information. Keyboard
hasn't much beside a pointer to SpiceKbdInterface, for other
interfaces this very likely will be different.
VDInterface has been renamed to SpiceBaseInterface. Dropped base_version
element, shlib versioning should be used instead. Dropped id element,
it is passed to spice_server_add_interface() instead. Now
SpiceBaseInterface has static information only, multiple interface
instances can share it.
Added SpiceBaseInstance struct for maintaining per-instance state
information. Adapted spice_server_{add,remove}_interface() functions
to the new world.
This patch adds a new file handle watch interface to libspice, featuring
three callbacks:
(1) watch_add() -- create a new file watch.
(2) watch_update_mask() -- change event mask. spice frequently
enables/disables write notification.
(3) watch_remove() -- remove a file watch.
libspice users must implement these functions to allow libspice
monitoring file handles.
The old interface (set_file_handlers) doesn't explicitly express the
lifecycle of a watch. Also it maps 1:1 to a qemu-internal function.
In case the way qemu implements file watches changes (someone sayed
QemuIONotifier?) this will break horribly. Beside that it is very
bad style.
Follwing patches will switch over users one by one to the new interface
and finally zap the old one.
Interfaces must be registered after spice_server_init().
The "next" callback is used to discover interfaces
registered before spice_server_init(). Which is a empty
list and thus pretty pointless. Remove it.
Surface creation now specifies the exact format, not only the bit depth
of each surface which is used for rendering.
Additionally we now actually store the surfaces in that format, instead
of converting everything to 32bpp when drawing or e.g. handling palettes.
The new command return dirty area to be used
by users that want spice to render localy or
into some framebuffer (sdl / vnc)
