14403117b5 Make channel client callbacks virtual functions
Rather than having an API to register client callbacks for each channel
type, make them vfuncs.

Since the client callbacks are registered identically for each channel
of the same type, it doesn't make sense for to require these to be
registered separately for each object.  It's cleaner to have these be
per-class properties, so they've been converted to virtual functions.

fb3c602d75 qxl: Add red_cursor_cmd_{new, ref, unref} helpers
Currently, the cursor channel is allocating RedCursorCmd instances itself, and then
calling into red-parse-qxl.h to initialize it, and doing something
similar when releasing the data. This commit moves this common code to
red-parse-qxl.[ch]
The ref/unref are not strictly needed, red_cursor_cmd_free() would
currently be enough, but this makes the API consistent with
red_drawable_{new,ref,unref}.

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().

5dbfbb4d78 channel: Move RedChannel::on_disconnect to RedChannelClient
This vfunc only has a RedChannelClient * argument, and most of the time,
it operates on RedChannelClient, not on RedChannel. Moreover, the only
time it's used is from RedChannelClient. This commit moves the vfunc to
RedChannelClient, which seems like a better fit for it.

7498675c1d Avoid leaking memory on invalid cursor commands
When a RedCursorCmd is passed to cursor_channel_process_cmd(), it
constructs a new CursorItem which takes ownership of that command. If
the cursor_cmd->type falls through to the default case of the switch
statement, we will print a warning and return without freeing the
CursorItem (and thus the RedCursorCmd).

03ab893412 channel: Remove RedChannel::handle_parsed
red_channel_client_parse() currently does roughly:

if (klass->parser) {
    parsed = klass->parser(msg, msg_size, &parsed_size);
    klass->handle_parsed(rcc, parsed_size, msg_type, parsed);
} else {
    klass->handle_message(rcc, msg_type, msg, msg_size);
}

The handle_parsed implementation expects a void * 'parsed' argument,
which will then be cast to the correct type. There is not really a need
to provide distinct handle_parsed/handle_message vfuncs, instead we can
say that if a RedChannel subclass provides a 'parser' vfunc, then it's
'handle_message' vfunc will be called with the parsed message, otherwise
it will be called with unparsed data (ie what handle_message currently
expects).

This makes the code slightly easier to follow as messages will always be
handled by the same vfunc.

0ace8a81c7 Remove third argument from red_channel_client_init_send_data()
This third argument (and the 'item' member of
RedChannelClient::priv::send_data) was a somewhat roundabout way to keep
the RedPipeItem alive until a message is sent, just in case some data
owned by that pipeitem was added to the marshaller by reference. This
was a rather confusing mechanism, however, since it did not have any
obvious connection to the _add_by_ref() call. It was never very clear
whether you needed to pass an item to this function or not. The previous
series of patches made this parameter unnecessary since the referencing
of the pipe item (or other related structure) is now more explicitly
connected to the calls to spice_marshaller_add_by_ref_full().

333ef51ece Refactor cursor marshalling for SET, INIT
Use spice_marshaller_add_by_ref_full() instead of
spice_marshaller_add_by_ref() to allow the marshaller to manage the
lifetime of the referenced data buffer rather than having to manage it
by passing a PipeItem to red_channel_client_init_send_data(). Since the
data is owned by CursorItem (which is not in fact a RedPipeItem, but is
owned by a pipe item and is itself refcounted), we take a reference on
the CursorItem when adding the data buf to the marshaller, and then
unreference it in the marshaller free func.

5c0f2e341c Avoid passing pipe item to red_channel_client_init_send_data()
The only time that the pipe item needs to be passed as the third
argument to red_channel_client_init_send_data() is when the pipe item
holds a data buffer that has been added to the marshaller by reference
(spice_marshaller_add_by_ref()) and needs to be kept alive until the
data has been sent. In all other cases, the item does not need to be
kept alive, so we can safely pass NULL for this third parameter.

3613ead4d8 marshaller: rename _add_ref() to _add_by_ref()
The spice_marshaller_add_ref() family of functions is confusing since it
sounds like you're incrementing a reference on the marshaller. What it
is actually doing is adding a data buffer to the marshaller by reference
rather than by value. Changing the function names to _add_by_ref() makes
this clearer.

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).
