435ea33540 Reduce C++ symbols visibility
This allows the compiler to do some more optimisations on the
produced binary.
To allows possible future portability include header/footer in
some helper header files.

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.

5ea0f68263 Rename StreamAgent to VideoStreamAgent
Just to avoid confusion between different uses of the word Stream (e.g.
RedStream) clarify that it's related to video streams

2e08354ce1 Rename Stream to VideoStream
To prevent confusion between Stream (a video stream) and RedStream (a
generic data stream between client and server), change the name to
VideoStream to be more explicit about what it is.

5ba0bc6663 dcc: handle preferred video codec message
[0] SPICE_MSGC_DISPLAY_PREFERRED_VIDEO_CODEC_TYPE

This message provides a list of video codecs based on client's order
of preference.

We duplicate the video codecs array from reds.c and sort it using the
order of codecs as reference.

This message will not change an ongoing streaming but it could change
newly created streams depending the rank value of each video codec
that can be set by spice_server_set_video_codecs()

97fcad82eb streaming: Always delegate bit rate control to the video encoder
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.

5193360594 Convert RedChannelClient hierarchy to GObject
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.

82d4edc75a Add DisplayChannelClientPrivate and CursorChannelPrivate structs
These need to be introduced at the same time since cache-item.tmpl.c
assumes that both of these classes will have a cache in the same place:
either within the channel client struct itself or (now) within a priv
struct owned by the channel client.

This encapsulates private data and prepares for porting to GObject.

a84a433e08 Limit direct access to DisplayChannelClient
Add a few more methods and accessors so that other files don't need to
manipulate the struct members directly. Move the struct definition to a
private header which only the dcc-* files will include.
