[PULL 01/14] spice: add module helpers

[Gerd Hoffmann]

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 ...

[PULL 02/14] spice: add QemuSpiceOps, move migrate_info

[Gerd Hoffmann]

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.

[Gerd Hoffmann]

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.

[PULL 10/14] modules: dependencies infrastructure

[Gerd Hoffmann]

Allow modules depending on other modules.

module_load_file() gets the option to export symbols (by not adding the
G_MODULE_BIND_LOCAL flag).

module_load_one() will check the module dependency list to figure (a)
whenever are other modules must be loaded first, or (b) the module
should export the symbols.

The dependencies are specificed as static list in the source code for
now as I expect the list will stay small.
