7720039ee0 red-channel-client: Move handle_message as a virtual function
The messages coming are from the client so it's a better place
to be in RedChannelClient instead of RedChannel.

176970f3f1 red-channel-client: Remove GObject type
Make all RedChannelClient hierarchy a C++ class.
This allows to use virtual methods.
Added a normal contructor instead or properties and g_object_new.

As we remove GObject conversion macros I added a macro XXX_CAST
to create a function to replace the old macro.
They will be removed when more type safety is introduced.

There's a new SPICE_CXX_GLIB_ALLOCATOR macro in red-common.h.
This macro, added to a class define the class allocator allowing
to use, in this case, GLib for allocation. This to avoid C++ library
dependency and to initialize all structure to 0 (not all fields
are manually initialized, will be improved with more encapsulation).

Currently the methods are mainly public, access will be modified
when more encapsulation (all functions in method) are done.

Some classes are now defined in the header, C++ uses access to
limit accessibility but for efficiency and type safety/inline and
other features require types to be defined in the headers.

Some fields were moved from XxxPrivate structure to class, C++
has accessibility.

Many destructors are defined as protected to forbid the use of
stack, this as these objects uses internal reference counting
to have normal pointers. Maybe in the future pointers like
std::shared_ptr could be used instead.

Reference counting is now implemented very easily using atomic
operations.

38cd152952 automake: Link with C++ linker
If automake sees no C++ files in the source it assumes have to
use C linker settings not linking C++ library.
This was not a problem as code did not use C++ libraries but next
patch will use pure virtual function call.
It could be provided but as later we will use RTTI use C++ library.

attache_worker was always spelled wrongly.
Use anonymous union (standard feature already used in different

Also removed a parameter from this new callback and deprecate

Due to C ABI removing a parameter is not an issue,
red-qxl.c:red_qxl_attach_worker will continue to pass the parameter,
