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

This allows the compiler to do some more optimisations on the

To allows possible future portability include header/footer in

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.

14403117b5 Make channel client callbacks virtual functions
Rather than having an API to register client callbacks for each channel
type, make them vfuncs.

Since the client callbacks are registered identically for each channel
of the same type, it doesn't make sense for to require these to be
registered separately for each object.  It's cleaner to have these be
per-class properties, so they've been converted to virtual functions.

a5aa2a2261 Use standard "Red" namespace
The objects RedsStream and RedsSASL are currently using the namespace
"Reds" rather than the standard "Red" namespace used throughout the rest
of the project. Change these to be consistent. This also means changing
method names and some related enumeration types.

The files were also renamed to reflect the change:
  reds-stream.[ch] -> red-stream.[ch]

5dbfbb4d78 channel: Move RedChannel::on_disconnect to RedChannelClient
This vfunc only has a RedChannelClient * argument, and most of the time,
it operates on RedChannelClient, not on RedChannel. Moreover, the only
time it's used is from RedChannelClient. This commit moves the vfunc to
RedChannelClient, which seems like a better fit for it.

afc4171c98 red-channel: Use RedChannelCapabilities directly to pass capabilities
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.

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.
