Jesse Larrew beb54a87ba libqtest: only call fclose() on open files
libqtest.c can segfault when calling fclose() if the pidfile wasn't
opened successfully. This patch fixes the issue.

Anthony Liguori 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.

Andreas Färber 872536bf5d qtest: Add MMIO support
Introduce [qtest_]{read,write}[bwlq]() libqtest functions and
corresponding QTest protocol commands to replace local versions in
libi2c-omap.c.

Also convert m48t59-test's cmos_{read,write}_mmio() to {read,write}b().

Andreas Färber 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.

Eduardo Habkost 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).

Paolo Bonzini 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.

Anthony Liguori 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.
