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:

This commit moves some DrawablePipeItem declarations to
display-channel.h, though the function implementations remain in
red_worker.c until they can be disentangled some more.

It's a regression introduced by commit e601e920bd. The logic error was
introduced when trying to achieve the following code[0]. but rewritten
to prefer an early return, which was wrogly negated.
[0]:
if (cursor_is_connected(worker)
&& !COMMON_CHANNEL(worker->cursor_channel)->during_target_migrate) {
red_channel_pipes_add_type(RED_CHANNEL(worker->cursor_channel),
PIPE_ITEM_TYPE_CURSOR_INIT);
}

In order to invalidate a single palette cache item, we were using
spice_marshall_msg_cursor_inval_one(), which is the marshal function
used to send an invalidation message for the Cursor channel's cache.
This didn't cause any problems because SPICE_MSG_CURSOR_INVAL_ONE and
SPICE_MSG_DISPLAY_INVAL_PALETTE have the same message ID and parameters,
but it's better to use the correct marshalling function.

Doing so allows us to remove the extra QXLInstance parameter from
cursor_item_unref() and makes the code a bit cleaner.
Also add cursor_item_ref().

Move the cursor-specific pipe item types to cursor-channel.h, and the
display-specific types to red_worker.c. Only leave the common
definitions in red_worker.h. This prepares for splitting the display
channel into a separate file.

There is no guarantee in the code that this can't be hit, so we should
cope with it (the condition can be reached easily by running the server
without waiting for blocked clients or pipe size)
The following commit will attempt to address this.
