[Qemu-devel] [PATCH v2 2/1] libqtest: add more exit status checks

["Michael S. Tsirkin" <mst@redhat.com>]

Add more checks on how did QEMU exit.

Legal ways to exit right now:
- exit(0) or return from main
- kill(SIGTERM) - sent by testing infrastructure

Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

Changes from v1:
- drop SIGTERM as suggested by Eric
