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.

These function are called on both sides of dispatcher so the
increment/decrement of the counter is done in multiple threads.
This caused the counter to not get incremented correctly and
freed the structure too early, leaving a dangling pointer in
the other thread.
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=1253375.

One more duplicate typedef, once in reds.c and another time in
reds-private.h
RedsState::agent_dev is defined in reds-private.h but only used in
reds.c, so longer term this could all be moved back to reds.c
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.
This inherits from RedCharDevice. Once all char device states are
converted, we can turn the associated vfuncs into RedCharDeviceClass
vfuncs.

This allows to stop using struct RedsState * rather than RedsState * in
headers which cannot include reds.h. This also allows to remove the
duplicate RedsState typedef in reds.h and reds-stream.h which is causing
issues with older gcc versions.
We can pass it a SndChannel rather than an opaque void* data pointer
which we then blindly cast.
This came to light through a -Wshadow warning as there was a local
variable 'data' in addition to the 'data' parameter.
VDIPortState and VDIReadBuf don't really need to be defined in a header
file as they are only used in reds.c

CursorChannel and DisplayChannel was initialized half in red_worker_new
and half in red_dispatcher_init using some accessor for RedWorker
(red_worker_get_cursor_channel and red_worker_get_display_channel).
Moving directly into red_worker_new make easier to follow code path.

Rename the function to channel_supports_multiple_clients() as
channel_is_secondary() is unclear and was coded to return the opposite
of what was originally intended.
Also there are few channel types and whether they support multiple
clients is totally static so we might as well delegate the check to
the compiler.

This should be the final piece of removing the global reds variable. We

AgentMsgFilter needs to know whether monitors config messages need to be
filtered or not. This used to be done from within
agent_msg_filter_config() using the global RedsState, but this got more
tricky as it was removed.
A first attempt a1e62fa5ae caused crashes on qemu startup with
"qemu-system-x86_64 -spice port=5900" (without -vga qxl). A second
attempt added a RedsState* argument to agent_msg_filter_config() which
in my opinion is not really nice from a layering point of view.
This new attempt makes sure AgentMsgFilter state is correct when the
filter is set to stop discarding all data, which allows to remove direct
use of RedsState from within AgentMsgFilter.
