Implement the following PowerISA v3.1 instructions:
xxmfacc: VSX Move From Accumulator
xxmtacc: VSX Move To Accumulator
xxsetaccz: VSX Set Accumulator to Zero
The PowerISA 3.1 mentions that for the current version of the
architecture, "the hardware implementation provides the effect of ACC[i]
and VSRs 4*i to 4*i + 3 logically containing the same data" and "The
Accumulators introduce no new logical state at this time" (page 501).
For now it seems unnecessary to create new structures, so this patch
just uses ACC[i] as VSRs 4*i to 4*i+3 and therefore move to and from
accumulators are no-ops.

When writing a register from the TCTXT memory region (4th page within
the IC BAR), we were overwriting the Presentation Controller (PC)
register at the same offset. It looks like a silly cut and paste
error.
We were somehow lucky: the TCTXT registers being touched are
TCTXT_ENx/_SET/_RESET to enable physical threads and the PC registers
at the same offset are either not used by our model or the update was
harmless.

This patch fixes another not-so-clear situation in Power ISA
regarding the inexact bits in FPSCR. The ISA states that:
"""
When Overflow Exception is disabled (OE=0) and an
Overflow Exception occurs, the following actions are
taken:
...
2. Inexact Exception is set
XX <- 1
...
FI is set to 1
...
"""
However, when tested on a Power 9 hardware, some instructions that
trigger an OX don't set the FI bit:
xvcvdpsp(0x4050533fcdb7b95ff8d561c40bf90996) = FI: CLEARED -> CLEARED
xvnmsubmsp(0xf3c0c1fc8f3230, 0xbeaab9c5) = FI: CLEARED -> CLEARED
(just a few examples. Other instructions are also affected)
The root cause for this seems to be that only instructions that list
the bit FI in the "Special Registers Altered" should modify it.
QEMU is, today, not working like the hardware:
xvcvdpsp(0x4050533fcdb7b95ff8d561c40bf90996) = FI: CLEARED -> SET
xvnmsubmsp(0xf3c0c1fc8f3230, 0xbeaab9c5) = FI: CLEARED -> SET
(all tests assume FI is cleared beforehand)
Fix this by making float_overflow_excp() return float_flag_inexact
if it should update the inexact flags.

According to Power ISA, the FI bit in FPSCR is non-sticky.
This means that if an instruction is said to modify the FI bit, then
it should be set or cleared depending on the result of the
instruction. Otherwise, it should be kept as was before.
However, the following inconsistency was found when comparing results
from the hardware (tested on both a Power 9 processor and in
Power 10 Mambo):
(FI bit is set before the execution of the instruction)
Hardware: xscmpeqdp(0xff..ff, 0xff..ff) = FI: SET -> SET
QEMU: xscmpeqdp(0xff..ff, 0xff..ff) = FI: SET -> CLEARED
As the FI bit is non-sticky, and xscmpeqdp does not list it as a field
that is changed by the instruction, it should not be changed after its
execution.
This is happening to multiple instructions in the vsx implementations.
If the ISA does not list the FI bit as altered for a particular
instruction, then it should be kept as it was before the instruction.
QEMU is not following this behavior. Affected instructions include:
- xv* (all vsx-vector instructions);
- xscmp*, xsmax*, xsmin*;
- xstdivdp and similars;
(to identify the affected instructions, just search in the ISA for
the instructions that does not list FI in "Special Registers Altered")
Most instructions use the function do_float_check_status() to commit
changes in the inexact flag. So the fix is to add a parameter to it
that will control if the bit FI should be changed or not.
All users of do_float_check_status() are then modified to provide this
argument, controlling if that specific instruction changes bit FI or
not.
Some macro helpers are responsible for both instructions that change
and instructions that aren't suposed to change FI. This seems to always
overlap with the sfprf flag. So, reuse this flag for this purpose when
applicable.

Commit 74c4912f09 changed check_tlb_flush() to use
tlb_flush_all_cpus_synced() instead of calling tlb_flush() on each
CPU. However, as side effect of this, a CPU executing a ptesync
after a tlbie will have its TLB flushed only after exiting its
current Translation Block (TB).
This causes memory accesses to invalid pages to succeed, if they
happen to be on the same TB as the ptesync.
To fix this, use tlb_flush_all_cpus() instead, that immediately
flushes the TLB of the CPU executing the ptesync instruction.

tl;dr: This allows Big Endian zImage booting via -kernel + x-vof=on.
QEMU loads the kernel at 0x400000 by default which works most of
the time as Linux kernels are relocatable, 64bit and compiled with "-pie"
(position independent code). This works for a little endian zImage too.
However a big endian zImage is compiled without -pie, is 32bit, linked to
0x4000000 so current QEMU ends up loading it at
0x4400000 but keeps spapr->kernel_addr unchanged so booting fails.
This uses the kernel address returned from load_elf().
If the default kernel_addr is used, there is no change in behavior (as
translate_kernel_address() takes care of this), which is:
LE/BE vmlinux and LE zImage boot, BE zImage does not.
If the VM created with "-machine kernel-addr=0,x-vof=on", then QEMU
prints a warning and BE zImage boots.
Note #1: SLOF (x-vof=off) still cannot boot a big endian zImage as
SLOF enables MSR_SF for everything loaded by QEMU and this leads to early
crash of 32bit zImage.
Note #2: BE/LE vmlinux images set MSR_SF in early boot so these just work;
a LE zImage restores MSR_SF after every CI call and we are lucky enough
not to crash before the first CI call.

-machine graphics=off is the usual way to tell the firmware or the OS that the
user wants a serial console. The pseries machine however does not support
this, and never adds the stdout-path node to the device tree if a VGA device
is provided. This is in addition to the other magic behavior of VGA devices,
which is to add a keyboard and mouse to the default USB bus.
Split spapr->has_graphics in two variables so that the two behaviors can be
separated: the USB devices remains the same, but the stdout-path is added
even with "-device VGA -machine graphics=off".

Staring with SEABIOS_HPPA_VERSION 6 the serial ports are now emulated as
on physical hardware, with LASI UART being serial port #0 and DINO UART
as serial port #1. On older versions those ports were swapped.
This SeaBIOS-hppa fix is needed to allow fixing the qemu serial
pass-through from host to guest.

As Daniel suggested, Add tests suite for rsakey, as a way to prove
that we can handle DER errors correctly.

Added gcryt implementation of RSA algorithm, RSA algorithm
implemented by gcrypt has a higher priority than nettle because
it supports raw padding.

Implement RSA algorithm by hogweed from nettle. Thus QEMU supports
a 'real' RSA backend to handle request from guest side. It's
important to test RSA offload case without OS & hardware requirement.
