Before this commit, red_channel_client_start_ping_timer() and
red_channel_client_cancel_ping_timer() had checks to be no-ops when
rcc->priv->latency_monitor.timer is NULL.
This commit adds a similar check to
red_channel_client_restart_ping_timer(), and removes explicit NULL
checks before calls to red_channel_client_{cancel,restart,start}_ping_timer()

Commit 590acf3c55 introduced a regression after migration:
PlaybackChannel::connection is never set even if a client is connected,
which means the playback channel is non-functional until a client
reconnects as all the snd_channel_set_xxx() method checks for a non-NULL
PlaybackChannel::connection before sending data to the client.
This commit slightly changes the code flow in
on_new_playback_channel_client()/playback_channel_client_constructed()
so that PlaybackChannel::connection is set regardless of what
red_client_during_migrate_at_target() returns. This is what was done
prior to 590acf3c55.
This resolves https://bugs.freedesktop.org/show_bug.cgi?id=100136

This is a particularly opaque part of the code for managing pending
Drawable operations. This patch adds documentation atempting to explain
these functions.
It can be useful for debug to know what the codec of the playback and
record channels are, so add a debug-level print statement indicating
this.

Main-channel-client.c has code to send pings when the statistics code is
enabled. This is done through a timer calling a ping_timer_cb callback.
However, this timer is created but never started, so this code is
actually dead-code.
Since this code does not seem to be doing much apart from sending the
pings (which can be achieved by simply setting monitor-latency to TRUE
in main_channel_client_create()), this commit removes it.

in main_channel_push_agent_connected(), it used the convenience function
red_channel_test_remote_cap() to determine whether to send the
AGENT_CONNECTED_TOKENS message, or the AGENT_CONNECTED message. However,
this function returns false if *any* one client doesn't support the
capability. We should instead check each individual client separately to
see if they support the capability.
This was a convenience function around
red_channel_client_test_remote_common_cap() that simply iterated over
each client (currently we only really support a single client anyway)
and returned TRUE only if all clients supported the capability. But
nobody ever called this wrapper function.
Both _test_remote_cap() and _test_remote_common_cap() are used as
boolean values, so change the return type from int to bool to follow our
coding standard.
This is a setting for determining whether to compress the audio playback
channel or not. It is variously typed as int or uint32_t. Convert it to
a 'bool' to make it more clear that it is a true/false value rather than
an enumeration or something like that.
The DUMP_BITMAP compile option enable some debugging code to
output image bitmaps in a subdirectory of /tmp.
However if this directory does not exists the server will crash
as not able to create a file in it.

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.
