Avoid not constant globals.
We started encapsulating all global state into RedsState however
there are still some global variable. This patch remove the
core_public global variable.
To implement this a new SpiceCoreInterface *public_interface
field is added to SpiceCoreInterfaceInternal and the
SpiceCoreInterfaceInternal* argument is passed to callbacks to
understand which external interface to use.

Noting that coding by hand these loop introduced some regression
I'm trying to introduce back from macros.
Before trying something harder to make possible to bind the type of
the content I'm trying some simple macro as were before.
I added the type to avoid some blindly void* casts.
Also the GListIter is introduced to avoid the possibility to exchange
easily some parameters.

Instead of using a Ring (and having a ring item link in every pipe
item), store them in a GQueue. This also necesitated changing
RedCharDeviceVDIPort->priv->read_bufs to a GList as well.
Also Optimise client pipe by passing pipe position instead of data.
This avoids having the search the data scanning all the queue changing
the order of these operations from O(n) to O(1).

Make RedsState::mig_target_clients into a GList to improve encapsulation

GList, a type implementation can be ignorant of whether they're

Previously we were creating a variable named 'dev_state' and then
apparently not using it. Well, we *were* actually using it, but in a
convoluted sort of way. Creating a new RedCharDevice has a
side-effect of setting itself as the 'st' attribute of
SpiceCharDeviceInstance. So 'dev_state' and 'char_device->st' are in
fact the same variable. But they were being used interchangeably, which
was rather confusing. For example
if (dev_state)
// do something with char_device->st
So this patch doesn't actually change anything, but it makes the code a
bit easier to follow.

Agent properties like file transfer or copy & paste can be disabled by
calling spice_server_set_agent_{copypaste, file_xfer} before the spice
server is initialized. In that case the call crashes the server because
the agent device is created after the initialization.
To avoid the crash this commit introduce a helper function for setting
the agent properties after the server is initialized.

Instead of having all other classes poke into the RedChannelClient
struct to get the RedClient associated with the channel client, call the
accessor function. This commit allows us to encapsulate RedChannelClient
and move it to its own file soon.
Eventually, during a seamless migration, qemu may finish to migrate
before the spice client even finished to connect all channels to
destination and informed the server. In this case,
main_channel_client_migrate_src_complete() will fall back to
switch-host method, and reds_mig_fill_wait_disconnect() is called to
complete the migration (disconnecting all channels).
reds_mig_cleanup() is called when all channels are disconnected, but
reds->mig_wait_connect is still TRUE, and it will call
migrate_connect_complete() instead of the expected
migrate_end_complete(). Setting reds->mig_wait_connect to FALSE when
reds_mig_fill_wait_disconnect() solves the issue.

g_object_new is a variadic function which takes property values.
As the compiler cannot check if these property values are correct,
make sure they are using casts.
