v2: * Added qemu_system_shutdown_force() API [Peter] Test cases are supposed to clean up even if they fail. Historically libqtest has leaked QEMU processes and files. This caused annoyances and buildbot failures so it was gradually fixed.
The solution we have for terminating the QEMU process if the test case fails was not very satisfactory. A SIGABRT handler in the test case sends SIGTERM to QEMU. This only works if the test case receives SIGABRT, not other ways in which it could die. The approach is ugly because it installs a global signal handler although libqtest is supposed to support multiple simultaneous instances. This patch series adds the new -chardev exit-on-eof option. QEMU will terminate if the socket/pipe/stdio receives EOF. That happens when the test case process terminates for any reason. By adding this option to -chardev we can use it with both -qtest and -qmp.
