OpenBIOS prints out the name of the detected CPU here, so looking for
this string is a nice test to verify that the CPU detection is still
working correctly.

Now that moxiesim supports the -bios parameter, we can check this machine
in the boot-serial tester, too, by supplying a mini bios that only writes
'T' characters to the UART.

QEMU only ships with some few firmware images, i.e. we can currently run
the boot-serial test only on a very limited set of machines. But writing
some characters to the default UART of a machine can often be done with
some few lines of assembly, so we add the possibility to the boot-serial
tester to use its own mini-kernels or mini-firmwares. We write such images
then into a file that we can load with the "-kernel" or "-bios" parameter
when we launch QEMU.

If the guest continuesly writes characters to the UART, we never leave
the inner while loop and thus never check whether we've reached the
timeout value. So if we fail to find the expected string in the UART
output, the test just hangs and never finishs. Use a counter to regularly
break out of the while loop to check the timeout.

We have several callers that were formatting the argument strings
themselves; consolidate this effort by adding new convenience
functions directly in libqtest, and update some call-sites that
can benefit from it.

Note that the new functions qtest_startf() and qtest_vstartf()
behave more like qtest_init() (the caller must assign global_qtest
after the fact, rather than getting it implicitly set).  This helps
us prepare for future patches that get rid of the global variable,
by explicitly highlighting which tests still depend on it now.

a qemu with an empty s390 guest will exit very quickly. This races
against the testsuite reading from the console pipe leading to
intermittent test suite failures. Using -no-shutdown will keep
the guest running.

A couple of tests for the work-in-progress 'powernv' machine type attempt
to test on POWER9 CPUs.  However the POWER9 CPU support is incomplete and
this doesn't really work.  In particular the firmware image we have
currently assumes the presence of the SDR1 register, which no longer exists
on POWER9.  We only got away with this so far, because of a different bug
which added SDR1 to POWER9 even though it shouldn't be there.

For now, remove POWER9 testing of powernv, POWER8 testing will do for now
until the POWER9 support is more complete.

The new powernv machine ships with a firmware that outputs
some text to the serial console, so we can automatically
test this machine type in the boot-serial tester, too.
And to get some (very limited) test coverage for the new
POWER9 CPU emulation, too, this test is also started with
"-cpu POWER9".

Some of the machines that we have got a firmware image for write
some output to the serial console while booting up. We can use
this output to make sure that the machine is basically working,
so this adds a test that checks the output of these machines
for some well-known "magic" strings.
