[PATCH v2 0/6] python/machine: use socketpair() for console socket |

Like we did for the QMP socket, use socketpair() for the console socket
so that hopefully there isn't a race condition during early boot where
data might get dropped on the floor.
May or may not help with various race conditions where early console
output is not showing up in the logs and/or potentially being missed by
wait_for_console_pattern.
V2:
- Fixed some Socket ownership/garbage collection problems
- Fixed callers of now-dropped VM arguments/properties
- added a dedicated sock_fd arg to ConsoleSocket()
- now using socketpair() for qtest console, too.
- dropped sock_dir arg from *all* machine.py classes
- Tested quite a bit more thoroughly ...
CI: https://gitlab.com/jsnow/qemu/-/pipelines/945067498
John Snow (6):
python/machine: move socket setup out of _base_args property
python/machine: close sock_pair in cleanup path
python/console_socket: accept existing FD in initializer
python/machine: use socketpair() for console connections
python/machine: use socketpair() for qtest connection
python/machine: remove unused sock_dir argument
