Doing a memset(0) on a SpiceStatNode does not create an empty/unattached
node, but instead creates a node '0'. This node could be non-existing,
or totally unrelated.
This patch creates a default '0' node as soon as the file is created.
This will make the behaviour of 0-filled nodes more in line with what

This reverts commit c3d237075b.
When you call gst_buffer_add_video_meta_full GStreamer assumes that
buffer is contiguous. Specifically GStreamer assumes that the first
chunk is big enough to hold a whole frame. This results usually in
some pixel shifts in the video. The pixel shifts you can see are
artifacts due to how the guest sends the frames.
Assuming you allocate the 2 chunks with 2 malloc:
p1 = malloc(size);
...
p2 = malloc(size);
Usually the memory allocator tend to allocate linearly if there are
space adding a prefix to describe next block leading to a memory
arrangement as:
+-------------------+
| p1 prefix |
+-------------------+
| p1 buffer |
+-------------------+
| p2 prefix |
+-------------------+
| p2 buffer |
+-------------------+
now if you take p1 pointer and you assume it points to a 2 * size
buffer you will get p2 prefix in the middle, this prefix is the pixel
shifts.
Problems happens specifically in gst_video_frame_map_id.
This bug is reported in https://bugzilla.gnome.org/show_bug.cgi?id=779524.

Send header and reply together.
This potentially save up to 160 bytes on the network which
is a considerable amount considering that the message is
about 50 bytes.
This as sending multiple chunks you can have different framing,
specifically:
- if you use TLS every chunk get encrypted separately
(reds-stream, currently usually 29 bytes for every chunks);
- tcp settings and no delay on socket. More likely with fast
connections or better network cards. The tcp framing is
usually about 80 bytes;
- additional tcp acknowledge (usually 64 bytes).
So 80 + 29 + 64 = 173 bytes.
