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.

In preparation for converting RedChannel to GObject, switch to using
RED_CHANNEL()-type macros for casting. For now they just do a regular
cast, but it helps reduce the size of the GObject patch to make it
easier to review.

Convert the RedChannelClient heirarchy into GObjects. Since the existing
constructors could fail and return NULL, I inherited the base channel
client from GInitable, which introduces a dependency on gio.
When using private structs with GObject, there's a maximum size of (I
think) 64k, which was exceeded by some of the private structs. To avoid
this limitation I changed some members to dynamically allocated.
In anticipation of porting to GObject, use casting macros (e.g.
MAIN_CHANNEL_CLIENT()) to cast RedChannelClient types. This will help
reduce the changeset slightly porting to GObject and thus make it easier
to review those upcoming changes.

Don't poke into the structure to get the channel
This prepares for encapsulating RedChannelClient a bit more and
separating it into its own source file.
