Sometimes it is useful to be able to automatically destroy a guest when a connection is closed. For example, kill an incoming migration if the client managing the migration dies. This introduces a map between guest 'uuid' strings and virConnectPtr objects. When a connection is closed, any associated guests are killed off. * src/qemu/qemu_conf.h: Add autokill hash table to qemu driver * src/qemu/qemu_process.c, src/qemu/qemu_process.h: Add APIs for performing autokill of guests associated with a connection * src/qemu/qemu_driver.c: Initialize autodestroy map
