Ensure an initial draw is sent immediately upon client connection
if the DMA-BUF video encoder is in use. Without this, a frame would
only be pushed when the screen content changes and the GPU renders
a new frame—which could take a while, causing delays for the client.
GStreamer now receives a duplicated file descriptor (fd) and takes
responsibility for closing it. This guarantees the buffer remains
available long enough. The previous fd mechanism is still retained
to ensure a valid scanout buffer is always available for a new
client.
We need to determine if the client is new enough to support multiple
codecs -- which might include any of the Gstreamer based ones.

Do not offset the time attempting to fix client latency.
Client should handle it by itself.
This remove entirely the delay introduced by the server.
This avoids surely possible time drifts in the client.
The server just sends it's concept of time without trying to force any
delay. Only one end should handle this delay in an attempt to
synchronize audio and video instead that doing it in both ends.

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.

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.

For each channel there are two set of capabilities, one
for the common ones and one for the specific ones.
A single set were almost always passed using 2 arguments,
a number of elements and an array but then before using
these were converted to a GArray.
Use a single structure (already available) to pass all
channel capabilites using a single argument.

red_channel_client_parse() currently does roughly:
if (klass->parser) {
parsed = klass->parser(msg, msg_size, &parsed_size);
klass->handle_parsed(rcc, parsed_size, msg_type, parsed);
} else {
klass->handle_message(rcc, msg_type, msg, msg_size);
}
The handle_parsed implementation expects a void * 'parsed' argument,
which will then be cast to the correct type. There is not really a need
to provide distinct handle_parsed/handle_message vfuncs, instead we can
say that if a RedChannel subclass provides a 'parser' vfunc, then it's
'handle_message' vfunc will be called with the parsed message, otherwise
it will be called with unparsed data (ie what handle_message currently
expects).
This makes the code slightly easier to follow as messages will always be
handled by the same vfunc.

The video encoders already have sophisticated bit rate control code that
can react to both stream reports sent by the client, and server frame
drop notifications. Furthermore they can adjust both the frame rate and
the image quality to best match the network conditions.
But if the client cannot send stream reports all this is bypassed and
instead the streaming code performs its own primitive bit rate control
that can only adjust the frame rate.
So this patch removes the code duplication and lets the video encoders
do their job.

Convert the RedChannelClient heirarchy into GObjects. Since the existing
constructors could fail and return NULL, I inherited the base channel
client from GInitable, which introduces a dependency on gio.
When using private structs with GObject, there's a maximum size of (I
think) 64k, which was exceeded by some of the private structs. To avoid
this limitation I changed some members to dynamically allocated.
