From spice_server_port_event API you can send port events to
any char device. Although currently this is used only for "port"
devices implemented in spicevmc.c this will allow to support
such events using different objects.
This will be used for instance for a streaming device which
will be a specific SpicePort implementation.

This is causing issues with potential improvements to the logging
system, and I've always found this usage a bit odd anyway.
Using spice_debug(""); was not possible as this triggers
-Wformat-zero-length warnings from our use of -Wall.

This is intended to hold the fields that only char-device.c has a use

This commit changes all functions returning TRUE/FALSE from having an
'int' return value to 'bool'.
This way it's obvious that such a function is not going to return
anything else than TRUE or FALSE.

The spice_marshaller_add_ref() family of functions is confusing since it
sounds like you're incrementing a reference on the marshaller. What it
is actually doing is adding a data buffer to the marshaller by reference
rather than by value. Changing the function names to _add_by_ref() makes
this clearer.

Most of the times the check is done externally
so moving inside the function reduce the code.

As the tokens counter were not being reset you could enter in a
situation where client thinks it has more tokens then server which
would eventually lead to client's disconnection from 0c5eca97f1
onwards (before it was crashing).
It is easy to check the above situation if you track the amount of
tokens you have in the client and simply kill and restart the agent
while doing some file transfer: the client could reach more then 13
tokens which should not really be possible.

RedCharDevice implementation had to callback into reds.c in order to let
it know a char device was being destroyed. Now that RedCharDevice is a
gobject, a weak reference can be used instead allowing to remove that
coupling.

There was an extra RedCharDeviceMsgToClientItem type whose only
purpose was to manage a linked list of items to send. GQueue has the
same purpose as this type in addition to being generic. As the length of
the send queue is tracked, a GQueue is more appropriate than a GList and
allow to remove RedCharDevice::send_queue_size.

Internally, use the method to set the 'sin' member variable so that we
don't have to duplicate the g_object_notify() calls, and there are
consistent debug statements whenever this value is modified. This also
means that we need to handle NULL arguments to this function.

Now that all derived classes use a type deriving from PipeItem for their
RedCharDeviceMsgToClient, we can make this explicit in the
RedCharDeviceClass vfuncs, and remove the RedCharDeviceMsgToClient
typedef.
This structure holding virtual function pointers was kept until now as a
RedCharDevice member in order to make the GObject conversion easier.
Now that all RedCharDevice children are converted to GObject, it can be
moved into RedCharDeviceClass.

spice_char_device_state_* becomes red_char_device_* and
spice_char_device_* also becomes red_char_device_*.
