Note that the commands are executed by spice-server.
The "skip" is only done on the "sleep" part of the
"slow" command-line option.
This is helpful to run quickly through uninsteresting commands
in a beginning of a recorded file and going slowly when
interesting parts appear

Apparently, after using g_option_context_parse with G_OPTION_REMAINING
argv is modified and should not be used.
This patch uses "file" instead of "argv" and makes sure
file is freed later.
No free is called upon error - exit takes care of it.
The req_cmd_notification callback is called by spice-server when it
has processed all commands and wants to be notified (by a wakeup) that
new commands have been appended to the command queue.
Replay utility tries to fill the commands when it detects that
spice-server is trying to read commands but there are no more commands.
However, new commands are appended in a separate thread so if the main
red worker loop on spice-server is really tight this request can
happen.
Avoid printing any message on this condition, message will be appended
and loop woken up when replay code can do it.

Send wakeups only when a command is available.
This emulate better what a guest driver should do (append the command
to the ring and then signal).

The replay file should start with a header such as
SPICE_REPLAY 1
Instead of soldiering on if we don't encounter this header, print a
warning and return NULL. Also exit with a failure if spice_replay_new()
returns a NULL object in main.

Make sure we don't handle event reserved to other loop contexts.

replay.c: In function 'replay_channel_event':
replay.c:226:16: error: zero-length gnu_printf format string
[-Werror=format-zero-length]
g_printerr("");
usage: spice-server-replay -p <port> -c <client command line> <cmdfile>
will run the commands from cmdfile ignoring timestamps, right after a
connection is established from the client, and will SIGINT the client
on end of cmdfile, and exit itself after waiting for the client.
spicy-stats from spice-gtk is useful for testing, it prints the summary
of the traffic on each channel.
You can also run with no client by doing:
spice-server-replay <cmdfile>
For example, the 300 MB file (compressed to 4 MB with xz -9) available
at [1] produces the following output:
spicy-stats total bytes read:
total bytes read:
inputs: 214
display: 1968983
cursor: 390
main: 256373
You could run it directly like so:
curl http://annarchy.freedesktop.org/~alon/win7_boot_shutdown.cmd.xz | \
xzcat | server/tests/spice-server-replay -p 12345 -c `which spicy-stats` -
Known Problems:
* Implementation is wrong. Should do a single device->host conversion
(i.e. get_virt), and then marshall/demarshall that (i.e. RedDrawable).
* segfault on file read done resulting in the above spicy-stats not
being reproducable (well, up to 1% yes).

Now based on glib including using an asyncqueue for reading the playback
file, and proper freeing of the allocated commands, with --slow,
--compression and a progress timer, and doesn't use more then nsurfaces.
