6c77d76f24 qemu: check guest status with qmp query-status
When guest panics or stops with unexpected internal
error, qemu process might still be running but we can
find out such situation with qmp. Then monitor can still
report such failures to watchers.

526d55b4af versions: Update golang to 1.10.4
Move to golang version 1.10.4 -- the oldest stable golang release at the
time of writing -- since golang 1.10+ is needed to make namespace
handling safe.

Re-ordered a couple of structs (moved `sync.WaitGroup` fields) to keep
the `maligned` linter happy. Previously:

``
virtcontainers/pkg/mock/cc_proxy_mock.go:24:18⚠️ struct of size 160 could be 152 (maligned)
virtcontainers/monitor.go:15:14⚠️ struct of size 80 could be 72 (maligned)
```

See:

- https://github.com/golang/go/issues/20676
- 2595fe7fb6

Also bumped `languages.golang.meta.newest-version` to golang version
1.11, which is the newest stable release at the time of writing.

Fixes #148.
