56db2e5843 qtest: unlink UNIX domain sockets after connecting
UNIX domain sockets are leaked when tests call abort(3) (indirectly via
glib assert functions).

Unlink the files immediately after the connection has been established
to avoid leaks.

1ad3c6abc0 qtest: unlink QEMU pid file after startup
After starting the QEMU process and initializing the QMP connection, we
can read the pid file and unlink it.

Just stash away the pid instead of the pid filename.  This way we can
avoid pid file leaks since running tests may abort(3) without cleanup.

2ad645d285 qtest: Use -display none by default
This avoids each test needing to add it to suppress windows popping up.

[Commit 7ceeedd016 ("blockdev-test: add
test case for drive_add duplicate IDs") and commit
43cd209803 ("qdev-monitor-test: add
device_add leak test cases") added qtest tests without specifying
-display none.

As a result, "make check" now tries to use graphics (GTK or SDL).  Since
graphics are not used by the test and inappropriate for headless "make
check" runs, add the missing -display none.

This fixes "make check" in the QEMU buildbot.

0c460dac03 libqtest: add qmp(fmt, ...) -> QDict* function
Add a qtest qmp() function that returns the response object.  This
allows test cases to verify the result or to check for error responses.
It also allows waiting for QMP events.

0d1aa05e9e libqtest: rename qmp() to qmp_discard_response()
Existing qmp() callers do not expect a response object.  In order to
implement real QMP test cases it will be necessary to inspect the
response object.

Rename qmp() to qmp_discard_response().  Later patches will introduce a
qmp() function that returns the response object and tests that use it.

8a8fd63734 qtest: don't use system command to avoid double fork
Currently we waitpid on the child process we spawn off that does
nothing more than system() another process.  While this does not
appear to be incorrect, it's wasteful and confusing so get rid of
it.

b73cf9e93f libqtest: Introduce qtest_qmpv() and convert remaining macro
In order to convert qmp() macro to an inline function, expose a
qtest_qmpv() function, reused by qtest_qmp().

We can't apply GCC_FMT_ATTR() since fdc-test is using zero-length format
strings, which would result in warnings treated as errors.

6bf0076643 libqtest: Wait for the right child PID after killing QEMU
When running "make check" with gcov enabled, we get the following
message:

   hw/tmp105.gcda:cannot open data file, assuming not executed

The problem happens because:

 * tmp105-test exits before QEMU exits, because waitpid() at
   qtest_quit() fails;
 * waitpid() fails because there's another process already
   waiting for the QEMU process;
 * The process that is already waiting for QEMU is the child created by
   qtest_init() to run system();
 * qtest_quit() is incorrectly waiting for the QEMU PID directly instead
   of the child created by qtest_init().

This fixes the problem by sending SIGTERM to QEMU, but waiting for the
child process created by qtest_init() (that exits immediately after QEMU
exits).

e0fea6b1e4 qtest: implement QTEST_STOP
It is quite difficult to debug qtest test cases without extra wrapper
scripts for QEMU or similar.  This patch adds a simple environment
variable-based trigger that sends a STOP signal to the QEMU instance
under test, before attempting to connect to its QMP session.

This will block execution of the testcase and give time to attach a
debugger to the stopped QEMU process.

039380a8e1 qtest: fix infinite loop when QEMU aborts abruptly
From Markus:

Makes "make check" hang:

    QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64 gtester -k --verbose -m=quick tests/crash-test tests/rtc-test
    TEST: tests/crash-test... (pid=972)
    qemu-system-x86_64: Device needs media, but drive is empty
[Nothing happens, wait a while, then hit ^C]
    make: *** [check-qtest-x86_64] Interrupt

This was due to the fact that we weren't checked for errors when
reading from the QMP socket.  This patch adds appropriate error
checking.
