This vfunc only has a RedChannelClient * argument, and most of the time,
it operates on RedChannelClient, not on RedChannel. Moreover, the only
time it's used is from RedChannelClient. This commit moves the vfunc to
RedChannelClient, which seems like a better fit for it.

The base RedChannel already keeps a list of channel clients, so there's
no need for the SndChannel to also keep track of the client itself.
Since the SndChannel only supports a single client (whereas other
channels may have some partial support for multiple clients), I've
provided a convenience function for getting the client and warning if
there is more than one.

The content of these functions almost exclusively deals with channel
client functionality except one line where the channel's active state is
set to TRUE.
These functions are called in two different places.
The first place is from the public API spice_server_record_start() and
spice_server_playback_start(). These functions should alter the
channel's active state, and then set the associated channel client to
active.
The second place is when a new channel client is created. In this
case, it is only called if the channel is already active, so it doesn't
make much sense to set the channel's active state inside of the
function.
To simplify things (and enable some future refactoring), this function
now only deals with the SndChannelClient. The functions have also been
renamed to reflect this fact. The SndChannel's active state is now only
modified from the public API functions.

When a new PlaybackChannelClient or RecordChannelClient is created,
there are several places where we make decisions based on whether the
client is active or not. But these checks are done before the 'active'
flag is ever set, so this code is effectively dead. This has been the
case since commit 6fdcb931 and d351bb35, so this code has not been
executed for approximately 7 years now.

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.

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.

red_channel_client_parse() currently does roughly:
if (klass->parser) {
parsed = klass->parser(msg, msg_size, &parsed_size);
klass->handle_parsed(rcc, parsed_size, msg_type, parsed);
} else {
klass->handle_message(rcc, msg_type, msg, msg_size);
}
The handle_parsed implementation expects a void * 'parsed' argument,
which will then be cast to the correct type. There is not really a need
to provide distinct handle_parsed/handle_message vfuncs, instead we can
say that if a RedChannel subclass provides a 'parser' vfunc, then it's
'handle_message' vfunc will be called with the parsed message, otherwise
it will be called with unparsed data (ie what handle_message currently
expects).
This makes the code slightly easier to follow as messages will always be
handled by the same vfunc.

You can see that SndChannelClient has much less field
as the code to read/write from/to client is reused from
RedChannelClient instead of creating a fake RedChannelClient
just to make the system happy.
One of the different between the old sound code and all other
RedChannelClient objects was that the sound channel don't use
a queue while RedChannelClient use RedPipeItem object. This was
the main reason why RedChannelClient was not used. To implement
the old behaviour a "persistent_pipe_item" is used. This RedPipeItem
will be queued to RedChannelClient (only one!) so signal code we
have data to send. The {playback,record}_channel_send_item will
then send the messages to the client using RedChannelClient functions.
For this reason snd_reset_send_data is replaced by a call to
red_channel_client_init_send_data and snd_begin_send_message is
replaced by red_channel_client_begin_send_message.
