dc7855967f4e did this for the TCP_NODELAY and IP_TOS calls; we should do
it for priority as well if necessary.
We also #ifdef the setting of the low-level socket priority based on
whether we have a definition of SO_PRIORITY available. This option is
not available on Illumos/Solaris platforms; however, since we set IP_TOS
anyway it is not a big deal to omit it here.

With Daniel P. Berrange's patches to allow use of pre-supplied fd's
as channels, we can no longer be sure that our connections are TCP
sockets, so it makes no sense to complain if a TCP/IP specific
setsockopt fails with an errno of ENOTSUP.
Note that this extends Daniel's commit 492ddb5d1d595e2d12208f4602b18e4432f4e6b4
which already added the same check to server/inputs_channel.c

Support for a header without a serial and without sub list.
red_channel: Support the two types of headers.
Keep a consistent consecutive messages serial.
red_worker: use urgent marshaller instead of sub list.
snd_worker: Sound channels need special support since they still don't use
red_channel for sending & receiving.

The code for setting and testing channel capabilities was
unnecessarily duplicated. Now it is in red_channel.
RedsChannel was dropped from Reds; It was used only for holding
the channels common capabilities, which are now held in RedChannel.

Fixes a valgrind discovered possible bug in spice-server - valgrind on
test_playback saw it, didn't see it happen with qemu.
The problem is that the frames buffers returned by spice_server_playback_get_buffer
are part of the malloc'ed SndChannel, whose lifetime is smaller then that of SndWorker.
As a result a pointer to a previously returned spice_server_playback_get_buffer could
remain and be used after SndChannel has been freed because the client disconnected.

Merging the functionality of reds::channel, into RedChannel.
In addition, cleanup and fix disconnection code: before this patch,
red_dispatcher_disconnect_display_client
could have been called from the red_worker thread
(and it must be called only from the io thread).
RedChannel holds only connected channel clients. RedClient holds all the
channel clients that were created till it is destroyed
(and then it destroys them as well).
Note: snd_channel still doesn't use red_channel, however it
creates dummy channel and channel clients, in order to register itself
in reds.
server/red_channel.c: a channel is connected if it holds at least one channel client
Previously I changed RedChannel to hold only connected channel clients and
RedClient, to hold all the channel clients as long as it is not destroyed.
usbredir: multichannel has not been tested, it just compiles.

They were globals before. This introduces api for other channels
to query the low bandwidth status. The queries themselves are still done
from the wrong context (channel and not channel client) but that's because
the decoupling of channel and channel client will be done in the following
patches.
Note that snd_worker.c got two copied function declarations that belong to
main_channel.h but can't be easily dragged into snd_worker.c since it still
uses it's own RedChannel struct.

That means RedClient tracks a ring of channels. Right now there will be only
a single client because of the disconnection mechanism - whenever a new
client comes we disconnect all existing clients. But this patch adds already
a ring of clients to reds.c (stored in RedServer).
There is a known problem handling many connections and disconnections at the
same time, trigerrable easily by the following script:
export NEW_DISPLAY=:3.0
Xephyr $NEW_DISPLAY -noreset &
for ((i = 0 ; i < 5; ++i)); do
for ((j = 0 ; j < 10; ++j)); do
DISPLAY=$NEW_DISPLAY c_win7x86_qxl_tests &
done
sleep 2;
done
I fixed a few of the problems resulting from this in the same patch. This
required already introducing a few other changes:
* make sure all removal of channels happens in the main thread, for that
two additional dispatcher calls are added to remove a specific channel
client (RED_WORKER_MESSAGE_CURSOR_DISCONNECT_CLIENT and
RED_WORKER_MESSAGE_DISPLAY_DISCONNECT_CLIENT).
* change some asserts in input channel.
* make main channel disconnect not recursive
* introduce disconnect call back to red_channel_create_parser
The remaining abort is from a double free in the main channel, still can't
find it (doesn't happen when running under valgrind - probably due to the
slowness resulting from that), but is easy to see when running under gdb.

The C specification reserves use of identifiers starting with __
to the compiler so we shouldn't use one such symbol.

These messages allow the guest to send the audio device volume to the
client. It uses an arbitrary scale of 16bits, which works good enough
for now.
Save VolumeState in {Playback,Record}State, so that we can send the
current volume on channel connection.
Note about future improvements:
- add exact dB support
- add client to guest volume change
Updated since v2:
- bumped record and playback interface minor version to allow
conditional compilation
Updated since v1:
- sync record volume on connection too

When using config.h, it must be the very first include in all source
files since it contains #define that may change the compilation process
(eg libc structure layout changes when it's used to enable large file
support on 32 bit x86 archs). This commit adds it at the beginning
of all .c and .cpp files

This fixes a typo in some function names, there should be no
functional change.

In C, the latter isn't a prototype for a function with no arg,
but declares a function with an undefined number of args.

Try to have a common base dispose() method for channels. For now, it
just free the caps.
Make use of it in snd_worker, and in sync_write() - sync_write() is
going to have default caps later on.

This is stylish change again. We are talking about a RedStream object,
so let's just name the variable "stream" everywhere, to avoid
confusion with a non existent RedPeer object.

This is required because we don't want to free messages that just
refer to the unparsed message (like SpiceMsgData).
Also, in the future we might need it for more complex demarshalling.

VDInterface has been renamed to SpiceBaseInterface. Dropped base_version
element, shlib versioning should be used instead. Dropped id element,
it is passed to spice_server_add_interface() instead. Now
SpiceBaseInterface has static information only, multiple interface
instances can share it.
Added SpiceBaseInstance struct for maintaining per-instance state
information. Adapted spice_server_{add,remove}_interface() functions
to the new world.
