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).

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.

Each test litters /tmp with several files: a pid file and two
sockets. Tidy up.

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.

accept() expects address_len to point to the length of the sockaddr on

After adding GCC_FMT_ATTR to qtest_sendf, more format errors are reported
by the compiler. These are fixed here.

Use PRIx64 to print 64 bit values to avoid truncation

This also includes a qtest wrapper script to make it easier to launch qtest
tests directly.
