API versioning

--------------



All plugins need to declare a symbol which exports the plugin API

version they were built against. This can be done simply by::



  QEMU_PLUGIN_EXPORT int qemu_plugin_version = QEMU_PLUGIN_VERSION;



The core code will refuse to load a plugin that doesn't export a

`qemu_plugin_version` symbol or if plugin version is outside of QEMU's

supported range of API versions.



Additionally the `qemu_info_t` structure which is passed to the

`qemu_plugin_install` method of a plugin will detail the minimum and

current API versions supported by QEMU. The API version will be

incremented if new APIs are added. The minimum API version will be

incremented if existing APIs are changed or removed.
