  hw/hppa/machine: Allow up to 3840 MB total memory

The physical hardware allows DIMMs of 4 MB size and above, allowing up
to 3840 MB of memory, but is restricted by setup code to 3 GB.
Increase the limit to allow up to the maximum amount of memory.

Btw. the memory area from 0xf000.0000 to 0xffff.ffff is reserved by
the architecture for firmware and I/O memory and can not be used for
standard memory.

An upcoming 64-bit SeaBIOS-hppa firmware will allow more than 3.75GB
on 64-bit HPPA64. In this case the ram_max for the pa20 case will change.

  hw/hppa/machine: Disable default devices with --nodefaults option

Recognize the qemu --nodefaults option, which will disable the
following default devices on hppa:
- lsi53c895a SCSI controller,
- artist graphics card,
- LASI 82596 NIC,
- tulip PCI NIC,
- second serial PCI card,
- USB OHCI controller.

Adding this option is very useful to allow manual testing and
debugging of the other possible devices on the command line.

Please note that this patch is not sufficient to completely boot up
NetBSD on the 64-bit C3700 machine yet.

  target/hppa: Fix PDC address translation on PA2.0 with PSW.W=0

Fix the address translation for PDC space on PA2.0 if PSW.W=0.
Basically, for any address in the 32-bit PDC range from 0xf0000000 to
0xf1000000 keep the lower 32-bits and just set the upper 32-bits to
0xfffffff0.

This mapping fixes the emulated power button in PDC space for 32- and
64-bit machines and is how the physical C3700 machine seems to map
PDC.

Figures H-10 and H-11 in the parisc2.0 spec [1] show that the 32-bit
region will be mapped somewhere into a higher and bigger 64-bit PDC
space.  The start and end of this 64-bit space is defined by the
physical address bits. But the figures don't specifiy where exactly the
mapping will start inside that region. Tests on a real HP C3700
regarding the address of the power button indicate, that the lower
32-bits will stay the same though.

  hw/hppa: Move software power button address back into PDC

The various operating systems (e.g. Linux, NetBSD) have issues
mapping the power button when it's stored in page zero.
NetBSD even crashes, because it fails to map that page and then
accesses unmapped memory.

Since we now have a consistent memory mapping of PDC in 32-bit
and 64-bit address space (the lower 32-bits of the address are in
sync) the power button can be moved back to PDC space.

This patch fixes the power button on Linux, NetBSD and HP-UX.

rfi is used to jump to smp_callin().

  tests/qtest/migration: Add a wrapper to print test names

Our usage of gtest results in us losing the very basic functionality
of "knowing which test failed". The issue is that gtest only prints
test names ("paths" in gtest parlance) once the test has finished, but
we use asserts in the tests and crash gtest itself before it can print
anything. We also use a final abort when the result of g_test_run is
not 0.

Depending on how the test failed/broke we can see the function that
trigged the abort, which may be representative of the test, but it
could also just be some generic function.

We have been relying on the primitive method of looking at the name of
the previous successful test and then looking at the code to figure
out which test should have come next.

Add a wrapper to the test registration that does the job of printing
the test name before running.

target/hppa qemu v8.2 regression fixes

There were some regressions introduced with Qemu v8.2 on the hppa/hppa64
target, e.g.:

- 32-bit HP-UX crashes on B160L (32-bit) machine
- NetBSD boot failure due to power button in page zero
- NetBSD FPU detection failure
- OpenBSD 7.4 boot failure

This patch series fixes those known regressions and additionally:

- allows usage of the max. 3840MB of memory (instead of 3GB),
- adds support for the qemu --nodefaults option (to debug other devices)

This patch set will not fix those known (non-regression) bugs:
- HP-UX and NetBSD still fail to boot on the new 64-bit C3700 machine
- Linux kernel will still fail to boot on C3700 as long as kernel modules are 
used.

Changes v2->v3:
- Added comment about Figures H-10 and H-11 in the parisc2.0 spec
  in patch which calculate PDC address translation if PSW.W=0
- Introduce and use hppa_set_ior_and_isr()
- Use drive_get_max_bus(IF_SCSI), nd_table[] and serial_hd() to check
  if default devices should be created
- Added Tested-by and Reviewed-by tags

Changes v1->v2:
- fix OpenBSD boot with SeaBIOS v15 instead of v14
- commit message enhancements suggested by BALATON Zoltan
- use uint64_t for ram_max in patch #1
