Some enhancements and fixes for the hppa target.
The major change is, that this patchset adds a new SeaBIOS-hppa firmware
which is built as 32- and 64-bit firmware.
The new 64-bit firmware is necessary to fully support 64-bit operating systems
(HP-UX, Linux, NetBSD,...).

Load the 64-bit SeaBIOS-hppa firmware by default when running on a 64-bit
machine. This will enable us to later support more than 4GB of RAM and is
required that the OS (or PALO bootloader) will start or install a 64-bit kernel
instead of a 32-bit kernel.
Note that SeaBIOS-hppa v16 provides the "-fw_cfg opt/OS64,string=3" option with
which the user can control what the firmware shall report back to the OS:
Support of 32-bit OS, support of a 64-bit OS, or support for both (default).
Wrap firmware loading inside !qtest_enabled() to avoid this warning with
qtest: "qemu-system-hppa: no firmware provided".

The QAPI generator forces you to document your stuff. Except for
command arguments, event data, and members of enum and object types:
these the generator silently "documents" as "Not documented".
We can't require proper documentation there without first fixing all
the offenders. We've always had too many offenders to pull that off.
Right now, we have more than 500. Worse, we seem to fix old ones no
faster than we add new ones: in the past year, we fixed 22 ones, but
added 26 new ones.
To help arrest the backsliding, make missing documentation an error
unless the command, type, or event is in listed in new pragma
documentation-exceptions.
List all the current offenders: 117 commands and types in qapi/, and 9
in qga/.

The description of @bins ends with a literal block:
# @bins: list of io request counts corresponding to histogram
# intervals, one more element than @boundaries has. For the
# example above, @bins may be something like [3, 1, 5, 2], and
# corresponding histogram looks like:
#
# ::
#
# 5| *
Except it actually ends *before* the block: the unindented '::' line
starts a new section. Makes no sense.
We could fix this by indenting the '::' line. Instead, double the
colon at the end of the preceding paragraph, and drop the '::' line.
This shifts the box for the literal block right in generated
documentation, so it lines up with the description.

Netbsd isn't able to detect a link on the emulated tulip card. That's
because netbsd reads the Chip Status Register of the Phy (address
0x14). The default phy data in the qemu tulip driver is all zero,
which means no link is established and autonegotation isn't complete.
Therefore set the register to 0x3b40, which means:
Link is up, Autonegotation complete, Full Duplex, 100MBit/s Link
speed.
Also clear the mask because this register is read only.

The BTLB helper function stores the BTLB info (four 32-bit ints) into
the memory of the guest. They are only available when emulating a 32-bit
CPU in the guest, so use "uint32_t" instead of "target_ulong" here.

HP-UX 11 and HP ODE tools use the "rsm 0,%reg" instruction in not priviledged
code paths to get the current PSW flags. The constant 0 means that no bits of
the PSW shall be reset, so this is effectively a read-only access to the PSW.
Allow this read-only access even for not privileged code.

Linux writes zeroes at bootup into the default ports for LASI audio and
LASI floppy controller to reset those devices. Allow writing to those
registers to avoid HPMCs.

Add the do_transaction_failed() handler to tigger a HPMC to the CPU
in case of I/O transaction errors.
This is a preparation commit.
We still lack implementation for some registers, so do not yet enable sending
HPMCs. Having this hunk here now nevertheless helps for the further
development, so that it can easily be enabled later on.

Firmware and qemu reads and writes the MAC address for the LASI LAN via
registers in LASI. Allow those accesses and return zero even if LASI
LAN isn't enabled to avoid HPMCs (=crashes).

The Astro/Elroy chip can work in either Hard-Fail or Soft-Fail mode.
Hard fail means the system bus will send an HPMC (=crash) to the
processor, soft fail means the system bus will ignore timeouts of
MMIO-reads or MMIO-writes and return -1ULL.
The HF mode is controlled by a bit in the status register and is usually
programmed by the OS. Return the corresponing values based on the current
value of that bit.

Instead of stopping the emulation, report a MEMTX_DECODE_ERROR if the OS
tries to access non-existent registers.
