After spice_char_device_state_destroy is called spicevmc should not keep
reference to that memory. state->chardev_st and sin->st point to the
same SpiceCharDeviceState and both should be set to NULL when it is
destroyed.
As SpiceCharDeviceState is only unref'ed on
spice_char_device_state_destroy the same device could be destroyed more
then once so the pointers that are freed should be set to NULL.

When no client is connect we should not need to keep the memory pool
used by char-device. In most situations this is not significant but
when using webdav this could mean freeing MAX_POOL_SIZE bytes

Otherwise the amount of unused memory could grow while transfering big
chunks of data. This change only means that once the memory was used it
will not be stored again after the limit was reached.

There are places were the could should definetly free the
SpiceCharDeviceWriteBuffer and places that it should only unref it. The
current use of spice_char_device_write_buffer_free was missleading.
This patch creates the spice_char_device_write_buffer_unref and properly
call these two functions.

Functions that check the equality of a path, brush, etc are moved the
display channel source file to prepare for moving the surfaces to the
display channel.

Instead of requiring the dispatcher to send a message to the worker to
create the display channel and cursor channel, just create them when
the worker is created.

Same approach as in spice_server_char_device_wakeup().
Avoid segmentation fault when the webdav channel (spice port channel) is
used with the vnc display:
