Peter reported that the boot-serial tester sometimes runs into timeouts
with SPARC guests. It's currently completely unclear whether this is due
to too much load on the host machine (so that the guest really just ran
too slow), or whether there is something wrong with the guest's firmware
boot. For further debugging, we need the serial output of the guest in
case of errors, so instead of unlinking the file immediately, this is
now only done in case of success. In case of error, print the name of the
file with the serial output via g_error() (which then also calls abort()
internally to mark the test as failed).

The consoles ("sclpconsole" and "sclplmconsole") can only be configured
with "-device" and "-chardev" so far. Other machines use the convenience
option "-serial" to configure the default consoles, even for virtual
consoles like spapr-vty on the pseries machine. So let's support this
option on s390x, too. This way we can easily enable the serial console
here again with "-nodefaults", for example:
qemu-system-s390x -no-shutdown -nographic -nodefaults -serial mon:stdio
... which is way shorter than typing:
qemu-system-s390x -no-shutdown -nographic -nodefaults \
-chardev stdio,id=c1,mux=on -device sclpconsole,chardev=c1 \
-mon chardev=c1
The -serial parameter can also be used if you only want to see the QEMU
monitor on stdio without using -nodefaults, but not the console output.
That's something that is pretty impossible with the current code today:
qemu-system-s390x -no-shutdown -nographic -serial none
While we're at it, this patch also maps the second -serial option to the
"sclplmconsole", so that there is now an easy way to configure this second
console on s390x, too, for example:
qemu-system-s390x -no-shutdown -nographic -serial null -serial mon:stdio
Additionally, the new code is also smaller than the old one and we have
less s390x-specific code in vl.c :-)
I've also checked that migration still works as expected by migrating
a guest with console output back and forth between a qemu-system-s390x
that has this patch and an instance without this patch.

Commit 92b540dac9 introduce a counter to handle the timeouts in a
better way. But in case ccnt reaches 512, the current read character is
ignored - and if that character is part of the string that we are looking
for, the test fails to match the string.
Almost all of the tests look for a string within the first 512 bytes of
firmware output, so the problem never triggered there. But the hppa test
that has been added recently looks for a longer string at the very end of
a long output, thus there's a chance that we miss a character there so
that the test fails unexpectedly. Fix it by *not* reading and dropping a
character if the counter reaches 512.

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 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.
