Rename qmp_query_spice() to qmp_query_spice_real(), add to QemuSpiceOps.

Add new qmp_query_spice() function which calls the real function via
QemuSpiceOps if available, otherwise return SpiceInfo.enabled = false.

Add QemuSpiceOps struct.  This struct holds function pointers to the
spice functions.  It will be initialized with pointers to the stub
functions.  When spice gets initialized the function pointers will
be re-written to the real functions.

The spice stubs will move from qemu-spice.h to spice-module.c for that,
because they will be needed for both "CONFIG_SPICE=n" and "CONFIG_SPICE=y
but spice module not loaded" cases.

This patch adds the infrastructure and starts with moving
qemu_spice_migrate_info() to QemuSpiceOps.

Add new spice-module.c + qemu-spice-module.h files.  The code needed to
support modular spice will be there.  For starters this will be only the
using_spice variable, more will follow ...

Header guard symbols should match their file name to make guard
collisions less likely.

Cleaned up with scripts/clean-header-guards.pl, followed by some
renaming of new guard symbols picked by the script to better ones.

This patch replaces the license header for those files that were either
GPL v2-or-v3, or GPL v2-only; the replacing license is GPL v2-or-later.
The code for task switching/handling, which is derived from KVM and
hence is GPL v2-only, is isolated in the new files (with this license)
x86_task.c/.h, and the corresponding compilation rule is added to
target/i386/hvf-utils/Makefile.objs.
