Factor out SimpleSpiceDisplay initialization into
qemu_spice_display_init_common() and call it from
both qxl.c (for vga mode) and spice-display.c

Add wrapper functions for all spice worker calls.

Spice worker does no longer process commands when it is stopped.
Otherwise, it might crash during migration when attempting to process
commands while the guest is not completely loaded.

The driver may change us to vga mode and still issue a QXL_IO_LOG,
which we can easily support.

We don't use qemu internals from spice server context any more.
Thus we don't also need to grab the iothread mutex from spice
server context.  And we don't have to temporarely release the
lock to avoid deadlocks.  Drop all the calls.

This patch moves the displaystate callback calls for setting the cursor
and the mouse pointer from spice server to qemu (iothread) context.
This allows us to simplify locking.

This patch moves the creation of spice screen updates from the spice
server context to qemu iothread context (display refresh timer to be
exact).  This way we avoid accessing qemu internals (display surface)
from spice thread context which in turn allows us to simplify locking.

One spice worker call lacks the unlock/relock calls,
which may lead to deadlocks, add them.

Live migration from and to spice 0.4 qxl devices isn't going to work.
Rip out the bits which attempt to support that.  Zap the subsection
logic which is obsolete now.  Bumb the version to make a clean cut.
This should obviously go in before 0.14 is released.

qxl is a paravirtual graphics card.  The qxl device is the bridge
between the guest and the spice server (aka libspice-server).  The
spice server will send the rendering commands to the spice client, which
will actually render them.

The spice server is also able to render locally, which is done in case
the guest wants read something from video memory.  Local rendering is
also used to support display over vnc and sdl.

qxl is activated using "-vga qxl".  qxl supports multihead, additional
cards can be added via '-device qxl".

[ v2: use qemu-common.h for standard includes    ]
