266ea334b2 tests/qtest: capture RESUME events during migration
When running migration tests we monitor for a STOP event so we can skip
redundant waits. This will be needed for the RESUME event too shortly.

aca0406958 tests/qtest: replace wait_command() with qtest_qmp_assert_success
Most usage of wait_command() is followed by qobject_unref(), which
is just a verbose re-implementation of qtest_qmp_assert_success().

cdf5ab5587 tests/qtest: switch to using event callbacks for STOP event
Change the migration test to use the new qtest event callback to watch
for the stop event. This ensures that we only watch for the STOP event
on the source QEMU. The previous code would set the single 'got_stop'
flag when either source or dest QEMU got the STOP event.

11936f0ef6 tests/qtest: get rid of some 'qtest_qmp' usage in migration test
Some of the usage is just a verbose way of re-inventing the
qtest_qmp_assert_success(_ref) methods.

ffd4727589 tests/qtest: get rid of 'qmp_command' helper in migration test
This function duplicates logic of qtest_qmp_assert_success_ref.
The qtest_qmp_assert_success_ref method has better diagnostics
on failure because it prints the entire QMP response, instead
of just asserting on existance of the 'error' key.

d7613ee216 tests/qtest: migration-test: Skip running test_migrate_fd_proto on win32
The test case 'test_migrate_fd_proto' calls socketpair() which does
not exist on win32. Exclude it. The helper function wait_command_fd()
is not needed anymore, hence exclude it too.

276dfd03f0 tests: wait max 120 seconds for migration test status changes
Currently the wait_for_migration_fail and wait_for_migration_complete
functions will spin in an infinite loop checking query-migrate status
to detect a specific change/goal. This is fine when everything goes
to plan, but when the unusual happens, these will hang the test suite
forever.

Any normally executing migration test case normally takes < 1 second
for a state change, with exception of the autoconverge test which
takes about 5 seconds. Taking into account possibility of people
running tests inside TCG, allowing a factor of x20 slowdown gives
a reasonable worst case of 120 seconds. Anything taking longer than
this is a strong sign that the test has hung, or the test should be
rewritten to be faster.

fd3540adb9 tests: ensure migration status isn't reported as failed
Various methods in the migration test call 'query_migrate' to fetch the
current status and then access a particular field. Almost all of these
cases expect the migration to be in a non-failed state. In the case of
'wait_for_migration_pass' in particular, if the status is 'failed' then
it will get into an infinite loop. By validating that the status is
not 'failed' the test suite will assert rather than hang when getting
into an unexpected state.

5e34005571 qtest: remove qtest_qmp_receive_success
The purpose of qtest_qmp_receive_success was mostly to process events
that arrived between the issueing of a command and the "return"
line from QMP.  This is now handled by the buffering of events
that libqtest performs automatically.

1e8a1fae74 test: Move qtests to a separate directory
The tests directory itself is pretty overcrowded, and it's hard to
see which test belongs to which test subsystem (unit, qtest, ...).
Let's move the qtests to a separate folder for more clarity.
