Found with modernize-use-override
This can be useful as compilers can generate a compile time error when:
The base class implementation function signature changes.
The user has not created the override with the correct
signature.

Like char devices, QXL devices need to be explicily started.
For some historical reason, char devices are started when in running
state. See commi bf1d9007b. Reading that commit comments, there was a
plan to provide an API to stop/start devices invidually, but that never
happened. Whether that API would really be useful now, I wonder.
For now, just follow the char devices behaviour and start QXL devices
added when vm_running.

Big endian machines on server are not officially supported but won't
hurt.
Messages from client are always encoded as little endian (as all
SPICE protocol).
Convert fields from little endian to host endian on some places
where numbers are used and not just binary copied.

Some compiler could generate some warning, like

Reduces usage of manual reference counting.
Avoids usage of new and use instead red::make_shared to both
create and own pipe items.
Use move semantic to reduce useless copies.

Most of the times each class has an associated constant so
allows to be able to define the constant at declaration time.

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.
It will also allows to use smart pointers.

Not much used, can be retrieved from the class if needed.
There are some apparent test removal on reds.cpp.
The test "if (!reds->vdagent)" apparently disappeared but it's included in
the while.
reds->agent_dev cannot be NULL as SPICE server allows only one agent and we
are into a member of an object so it must be reds->agent_dev.get() == this.
As there's only an agent and as the interface (sin) is extracted from that
agent it must be reds->agent_dev.get() == sin->st and either reds->vdagent
== sin or reds->vdagent == NULL.

socket_close is mapped to close under Unix but under Windows
you should call closesocket instead so call socket_close which
will map to the proper close function on both environments.

Darwin does not have MSG_NOSIGNAL but allows to set a SO_NOSIGPIPE
option to disable sending SIGPIPE writing to closed socket.
Note that *BSD has the SO_NOSIGPIPE option but does not affect all
write calls so instead continue to use MSG_NOSIGNAL instead on
that systems.

Instead of including spice.h directly include an header that wraps
it. This allows to remove the SPICE_SERVER_INTERNAL define.
Currently is used to rename SpiceCharDeviceInstance to RedCharDevice
and reduce its visibility to hidden. This remove some warnings
and some weird code in the source.

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
