104aa6e1af Remove GObject from RedChannel
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

669df4fb38 red-channel-client: Make send_item a virtual function
The items are send from RedChannelClient so move the callback
to a virtual function in RedChannelClient instead of RedChannel.

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.
