Also increase precision making sure that number of precision is

Removing an interface cause SpiceBaseInstance->st to be set to NULL.

As SpiceBaseInstance should not be used after this call make sure

When a client disconnects remove it from the list of clients connected
to the spice char-device.
This was caused by commit 1cec1c5118
("reds: Make VDIPortState a GObject") as the lifespan of RedCharDevice
was changed.
This could be reproduced with:
- start rhel7 machine
- connect remote viewer (RV)
- RV: login
- connect ssh
- SSH: stop agent
- disconnect RV
- SSH: start agent
- connect to RV
and caused (using address sanitizer):

We may get stream reports after the stream has been closed, and even, in
extreme cases, after a new stream has started reusing the same stream
id. Neither case should cause the server to crash.
So restore dcc_handle_stream_report() to how it was before being moved
to dcc.c.

Instead of exporting 2 methods to get number of channels, and to fill

RedCharDevice implementation had to callback into reds.c in order to let

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.

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.
Since PipeItem is already refcounted, this allows to remove various
layers of ref/unref helpers from reds.c, and use the generic
pipe_item_{ref, unref} instead.
A user-defined callback is called when the refcount drops to 0.
Reference counting is manually coded for several classes deriving from
PipeItem, so this change will help to share this code, and allow to remove
some ref/unref virtual functions in some interfaces when we can assume
every instance derives from this base class.
