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.

Any data that is added to the marshaller by reference (using e.g.
spice_marshaller_add_by_ref_full()) is freed during
spice_marshaller_reset(). But the marshaller is not currently reset
until we begin to send the next message (in
red_channel_client_send_item()). This means that the sent message data
lives longer than expected and can violate some assumptions in other
parts of the code.
To make sure that the data is cleaned up right after being sent, I've
added a reset call to clear_sent_item() and called that function from
_on_out_msg_done(). This means that _restore_main_sender() no longer
needs to reset the marshaller, and we no longer need to call
_reset_sent_item() within _on_out_msg_done() (since this function is
called from _clear_sent_item()).
This prepares the way for refactoring
red_channel_client_init_send_data() to change how we keep the
RedPipeItem alive while sending a message.

We should replace the video_codecs GArray only after the parsing of
input is done, otherwise we might lose previous configuration.
Tests were updated to match this situation. Input that fails to
replace video_codecs are considered bad.

The partial expression "MSEC_PER_SEC * size * 8" can overflow if
size is 536870 or more. This as the operation is done using
32 bit unsigned integers. Being the size potentially double of
a compressed frame size the limit can be easily reached.
As get_average_frame_size already return a 64 bit use 64 bit
even for the size to avoid the integer overflow.

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.

hramrach on IRC had an issue with audio not working. He was using
suse and his qemu defaulted to using the pulseaudio audio driver instead
of spice. Explicitly setting the audio driver to spice using the
QEMU_AUDIO_DRV environment variable solved the problem. Add this tip to
the manual for others having the same issue in the future.
Reduce GObject changes coming in the next commit since we'll need to
change how we access the marshaller anyway. This will make the
following commits easier to review.

When qemu (for example) delivers audio samples to the spice server, it
does so by requesting a buffer from the spice server
(spice_server_playback_get_buffer()), filling them with audio data, and
then calling spice_server_playback_put_samples() to send them to the
client. Between the call to _get_buffer() and the call to
_put_samples(), we need to ensure that the buffer remains valid. Since
this buffer is allocated within PlaybackChannelClient, we did this by
incrementing a ref on the PlaybackChannelClient in _get_buffer(), and
decrementing the ref in _put_samples(). This has the effect of
potentially keeping the PlaybackChannelClient alive after the spice
client has disconnected.
This was not a problem when PlaybackChannelClient was a simple helper
class. But we intend to change PlaybackChannelClient so that it
inherits from RedChannelClient. In that case, the reference taken in
_get_buffer() would result in the RedChannelClient (and associated
RedChannel, etc) being kept alive longer than expected. To avoid this,
we add an additional ref-counted adapter class (AudioFrameContainer)
that owns the allocated audio frames and can outlive the
RedChannelClient if necessary. When the client is freed, the
AudioFrameContainer is just unreferenced.
