This patch series adds support for module meta-data.  Today this is
either hard-coded in qemu (see qemu_load_module_for_opts) or handled
with manually maintained lists in util/module (see module_deps[] and
qom_modules[]).  This series replaced that scheme with annotation
macros, so the meta-data can go into the module source code and -- for
example -- the module_obj() annotations can go next to the TypeInfo
struct for the object class.

Patches 1-3 put the infrastructure in place:  Add the annotation macros,
add a script to collect the meta-data, add a script to compile the
meta-data into C source code which we can then add to qemu.

Patches 4-12 add annotations macros to the modules we have.

Patches 13-15 put the modinfo database into use and remove the
module_deps[] and qom_modules[] lists.

Patch 16 adds two tracepoints for easier trouble-shooting.

Patches 17-19 add support for target-specific modules.

Patches 20-14 start building accelerators modular.  So far it is
only qtest (all archs) and a small fraction of tcg (x86 only).

take care,
  Gerd
