ab1348486d worker: Simplify flush_commands()
red_disconnect_display() is duplicating what red_channel_disconnect()
already does, so red_disconnect_display() and red_disconnect_cursor()
are actually identical code-wise. We can directly call
red_channel_disconnect() from flush_commands() rather than passing a
'red_disconnect_t disconnect' argument to that function.

becd0d30f6 cursor: Remove cursor_channel_disconnect()
cursor_channel_disconnect() calls
cursor_channel_client_reset_cursor_cache() on all CursorChannelClient
associated with the current CursorChannel before calling
red_channel_disconnect().

red_channel_disconnect() will iterate over all CursorChannelClient
calling red_channel_client_disconnect(), which will eventually call
CursorChannelClient::on_disconnect. This will in turn
cursor_channel_client_reset_cursor_cache(), so calling it in
cursor_channel_disconnect() before calling red_channel_disconnect() is
redundant.

cursor_channel_disconnect() can thus be replaced by a direct call to
red_channel_disconnect().

975d10c9ef red-qxl: Avoid using dangling pointers to RedClient
A RedClient can be freed from the main thread following a main channel
disconnection (reds_client_disconnect). This can happen while another
thread is allocating a new channel client for that client.
To prevent the usage of a pointer which can be invalid
take ownership of the pointer.
Note that we don't need this when disconnecting as disconnection is
done synchronously (the dispatch messages are registered with
DISPATCH_ACK).

For each channel there are two set of capabilities, one

A single set were almost always passed using 2 arguments,
a number of elements and an array but then before using
these were converted to a GArray.
Use a single structure (already available) to pass all
channel capabilites using a single argument.

ce06958fb8 Improve statistic code interface
Use new structures and functions to implement the statistics code.
Use inline functions instead of macros for increased type-safety.
If statistics are disabled, the structures and functions become
empty. This confines the configuration-specific #defines to the
statistics implementation itself and avoids the need for #defines in
the calling functions. This greatly reduces the chance of accidentally
breaking the build for one configuration or the other. The reds option
was removed from stat_inc_counter() as it was not used.

1b15983415 Make QXLMessage handling safe
The QXLMessage has no size so potentially a guest could give an
address that cause the string to overflow out of the video memory.
The current solution is to parse the message, release the resources
associated without printing the message from the client.
This also considering that the QXLMessage usage was deprecated
a while ago (I don't know exactly when).
This patches limit the string to 100000 characters (guest can feed
so much logs in other way) and limit to video memory.

207cd10dcc Limit maximum "n-surfaces" via param spec
In commit beec1b41, we manually limited this property value in
_set_property(). But there's a simpler way to do it: via the param spec
for the property.

This also means that we can remove the warning log in red_worker_new()
since GObject will automatically warn if a property is assigned a value
outside of its valid range.

Change the minimum and default value for this property from 0 to 1 so
that we always have a primary surface.

c5059edb82 Remove red_pipe_add_verb family function
These functions were implementing the same stuff as empty
messages functions provided by RedChannel so reuse them.

The implementation seems a bit different but the result
is the same. Specifically:
- RedEmptyMsgPipeItem::msg is int while RedVerbItem::verb was
  uint16_t however this data goes into the message type which
  is uint16_t (a 16 bit on the network protocol);
- red_channel_client_send_empty_msg calls
  red_channel_client_begin_send_message while red_marshall_verb
  does not. However red_marshall_verb is called only by
  cursor_channel_send_item and dcc_send_item which always
  calls red_channel_client_begin_send_message.
  Note that in dcc_send_item when an empty message is sent
  red_channel_client_send_message_pending always returns
  true;
- when a PipeItem is created red_channel_client_pipe_add_empty_msg
  calls red_channel_client_push while red_pipe_add_verb does not.
  This actually make very little difference as this kind of item are
  never removed from the queue and a push is forced in every case
  running the event handler for the stream watch (see
  prepare_pipe_add and red_channel_client_event).

and a small bit of refactoring to avoid poking into DisplayChannel

accessing private data, so at the moment the private struct is defined
