QEMU modules — QEMU documentation

# QEMU modules

module info annotation macros

`scripts/modinfo-collect.py` will collect module info, using the preprocessor and -DQEMU_MODINFO.

`scripts/modinfo-generate.py` will create a module meta-data database from the collected information so qemu knows about module dependencies and QOM objects implemented by modules.

See `*.modinfo` and `modinfo.c` in the build directory to check the script results.
