Hans de Goede f3f8ebe91b server/spicevmc: Don't destroy the rcc twice 
spicevmc calls red_channel_client_destroy() on the rcc when it disconnects
since we don't want to delay the destroy until the session gets closed as
spicevmc channels can be opened, closed and opened again during a single
session.

This causes red_channel_client_destroy() to get called twice, triggering
an assert, when a connected channel gets destroyed.

This was fixed with commit ffc4de01e6 for
the case where: a spicevmc channel was open on client disconnected, and
the main channel disconnect gets handled first.

But the channel can also be destroyed when the chardev gets unregistered
with the spice-server. This path still triggers the assert.

This patch fixes this by adding a destroying flag to the rcc struct, and
also moves the previous fix over to the same, more clean, method of
detecting this special case.

   SPICE: Simple Protocol for Independent Computing Environments
   =============================================================

SPICE is a remote display system built for virtual environments which
allows you to view a computing 'desktop' environment not only on the
machine where it is running, but from anywhere on the Internet and
from a wide variety of machine architectures.

Installation
------------

The SPICE package uses GNU autotools, so the build install process
follows the standard process documented in the INSTALL file. As a
quick start you can do

  ./configure --prefix=/usr --sysconfdir=/etc \
        --localstatedir=/var --libdir=/usr/lib
  make
  sudo make install

Or to install into a private user specific location

  ./configure --prefix=$HOME/spice
  make
  make install

The following mandatory dependancies are required in order to
build SPICE

    Spice protocol >= 0.9.0
    Celt           >= 0.5.1.1, < 0.6.0
    Pixman         >= 0.17.7
    OpenSSL
    libjpeg
    zlib
    Cyrus-SASL

The following optional dependancies increase the available
functionality

    GE Gui         >= 0.6.0,  < 0.7.0   (GUI app support)
    OpenGL                              (GUI app support)
    Alsa                                (Linux support)
    XRandR         >= 1.2               (X11 support)
    Xinerama       >= 1.0               (X11 support)
    libcacard      >= 0.1.2             (Smartcard support)
    Slirp                               (Tunnelling support)

Communication
-------------

To communicate with the development team, or to post patches
there is a technical mailing list:

   http://lists.freedesktop.org/mailman/listinfo/spice-devel

There is also a mailing list for new release announcements:

   http://lists.freedesktop.org/archives/spice-announce/

To view known bugs, or report new bugs, in SPICE visit

   https://bugs.freedesktop.org/describecomponents.cgi?product=Spice

Bugs found when using an OS distribution's binary packages should
be reported to the OS vendors' own bug tracker first.

The latest SPICE code can be found in GIT at:
