[Qemu-devel] [PATCH V3 0/2] tests: Fix possible deadlock in qtest initialization

[Marcel Apfelbaum <marcel.a@redhat.com>]

V2 -> V3:
     Addressed Eric Blake's review:
     - Corrected a typo.
     - Replace the commented Makefile part

V1 -> V2:
    Addressed Stefan Hajnoczi's review:
    - Dropped qtest_state_valid API
    - Moved socket options in socket_accept. 

'socket_accept' waits for Qemu to initialize its unix socket.
If Qemu encounters an error during command line parsing,
it can exit before initializing the communication channel.

Using a timeout for sockets fixes the issue, but is not
enough. We need to know which test from check-qtest-*
fails.

We tweak the Makefile to produce per-test output.
The effect is that the output will grow, but we will know
which qtest failed. This helps when an assert is made on
other code and not in the test itself.
