For non-gl/remote clients, if there is no stream associated with
the DisplayChannel, then we create a new stream. Otherwise, we
just update the current stream's timestamp.

Store pointers to surface object in "surfaces" and allows to
have different surfaces with same ID in memory.
The surface was keep "busy" if there was pending drawing around.
Consider the following case:
1- receive drawing command
2- queue command on DCCs
3- destroy surface
4- send draw
Previously at point 4) you would have to use a surface from
"surfaces" which was destroyed, that is we would have to maintain
the pointer (and canvas) to the surface until reference counter
was 0.
However consider this case:
1- receive drawing command
2- queue command on DCCs
3- destroy surface
4- create surface
5- send draw
What would happen in point 4) ?
We could not change the surface as it will be used by point 5).
To avoid this the code attempts to wait the commands to release the
surface. However this can be an issue, you can't force the clients
to receive pending data if network is slow.
So this patch change this allowing to create surfaces while the old
version will still be used.
This is also more clean from the reference pointer prospective,
as the reference is increased for a specific surface.
Note that now instead of checking for canvas to not be NULL a
simple check for surface pointer is enough.

Mostly left on dcc-send.cpp.
Other minor too.
The change in BitmapData seems odd but the id for cached image
was not used so the only information left was the surface.

As we use reference counting is more direct to use direct pointers.
Also this will allow to have a surface in a "released state"
reducing the complexity of code destroying a surface.

Most of the times each class has an associated constant so
allows to be able to define the constant at declaration time.

This allows to:
- reuse reference counting;
- avoid having to manually call g_free to release item memory;
- assure item is initialized;
- avoids some manual casts.
It will also allows to use smart pointers.

The patch seems pretty huge but mainly are mechanical steps:
- remove GObject declarations
- do not inherit from GObject
- add SPICE_CXX_GLIB_ALLOCATOR to avoid using C++ allocators
- CLASS_init and CLASS_constructor code goes into C++ constructor
- CLASS_dispose and CLASS_finalize code goes into C++ destructor
- g_object_new is replaced by new operator
- class members goes into virtual methods
- class parameters became argument to constructor
- use push-visibility.h and pop-visibility.h to limit visibility
- temporary use XXX_CAST for old GObject casts, they will
be replaced
- g_object_get is replaced by accessors

Now that we have a refcounted RedSurfaceCmd, we can store the command
itself in DisplayChannel rather than copying QXLReleaseInfoExt. This
will let us move the release of the QXL guest resources in red-parse-qxl
in the next commit.

display-channel.h contains lots of information used by different
DisplayChannel components.
In the past all RedWorker, CursorChannel and DisplayChannel code was in
a single file. Since lots of code to handle DisplayChannel is still in
RedWorker, display-channel.h contains a lot of declarations so that they
can be accessed from RedWorker.
Moving declarations that are not needed by RedWorker and other external
class components helps to reduce dependencies between RedWorker and
DisplayChannel.

Use new structures and functions to implement the statistics code.
Use inline functions instead of macros for increased type-safety.
If statistics are disabled, the structures and functions become
empty. This confines the configuration-specific #defines to the
statistics implementation itself and avoids the need for #defines in
the calling functions. This greatly reduces the chance of accidentally
breaking the build for one configuration or the other. The reds option
was removed from stat_inc_counter() as it was not used.

The Surface and Display channels each have a 'current_list' Ring, and
Surface also has a 'current' Ring. these names are confusing, so at
minimum, add a comment indicating the type of object they hold. The
DisplayChannel::current_list already had a comment, but it was
incorrect.
