Currently objects including "hw/ppc/spapr.h" are forced to be
target specific due to the inclusion of "vof.h" in "spapr.h".
"spapr.h" only uses a Vof pointer, so doesn't require the structure
declaration. The only place where Vof structure is accessed is in
spapr.c, so include "vof.h" there, and forward declare the structure
in "spapr.h".

Some SDHCI IP can be synthetized in various endianness:
https://github.com/u-boot/u-boot/blob/v2021.04/doc/README.fsl-esdhc
- CONFIG_SYS_FSL_ESDHC_BE
ESDHC IP is in big-endian mode. Accessing ESDHC registers can be
determined by ESDHC IP's endian mode or processor's endian mode.
Our current implementation is little-endian. In order to support
big endianness:
- Rename current MemoryRegionOps as sdhci_mmio_le_ops ('le')
- Add an 'endianness' property to SDHCIState (default little endian)
- Set the 'io_ops' field in realize() after checking the property
- Add the sdhci_mmio_be_ops (big-endian) MemoryRegionOps.

In commit da0bd74434 we refactored bdrv_drain_all_begin() to pull out
the non-polling part into bdrv_drain_all_begin_nopoll(). This change
broke record-and-replay, because the "return early if replay enabled"
check is now in the sub-function bdrv_drain_all_begin_nopoll(), and
so it only causes us to return from that function, and not from the
calling bdrv_drain_all_begin().
Fix the regression by checking whether replay is enabled in both
functions.
The breakage and fix can be tested via 'make check-avocado': the
tests/avocado/reverse_debugging.py:ReverseDebugging_X86_64.test_x86_64_pc
tests/avocado/reverse_debugging.py:ReverseDebugging_AArch64.test_aarch64_virt

Begin weaning user-only away from PageDesc.
Since, for user-only, all TB (and page) manipulation is done with
a single mutex, and there is no virtual/physical discontinuity to
split a TB across discontinuous pages, place all of the TBs into
a single IntervalTree. This makes it trivial to find all of the
TBs intersecting a range.
Retain the existing PageDesc + linked list implementation for
system mode. Move the portion of the implementation that overlaps

According to GLib changelog [1], since version 2.73.2 GLib is using
libpcre2 instead of libpcre. As a result, qemu-ga MSI installation
fails due to missing DLL when linked with the newer GLib.
This commit makes wixl to put the right libpcre version into the MSI
bundle: either libpcre-1.dll or libpcre2-8-0.dll, depending on the
present version of GLib.

This patch translates GLib-specific log levels to system ones, so that
they may be used by both *nix syslog() (as a "priority" argument) and
Windows ReportEvent() (as a "wType" argument).
Currently the only codepath to write to "syslog" domain is slog()
function. However, this patch allows the interface to be extended.
Note that since slog() is using G_LOG_LEVEL_INFO level, its behaviour
doesn't change.

This commit allows QGA to write to Windows event log using Win32 API's
ReportEvent() [1], much like syslog() under *nix guests.
In order to generate log message definitions we use a very basic message
text file [2], so that every QGA's message gets ID 1. The tools
"windmc" and "windres" respectively are used to generate ".rc" file and
COFF object file, and then the COFF file is linked into qemu-ga.exe.

PCI AER error status is 32 bit. The HMP command supports both
symbolic and numeric error status: anything that isn't a known
symbolic value is parsed as number with strtol(). Issues:
* Empty argument yields value zero.
* Range errors from strtol() are ignored, value is UINT32_MAX.
* Values not representable in uint32_t are silently truncated.
Fix to reject such input by switching to strtoui().

We compile pci-hmp-cmds.c always, but pci-qmp-cmds.c only when
CONFIG_PCI. hw/pci/pci-stub.c keeps the linker happy when
!CONFIG_PCI. Build pci-hmp-cmds.c that way, too.

QMP query-pci and HMP info pci can behave differently when there are
no PCI devices. They can report nothing, like this:
qemu-system-aarch64 -S -M spitz -display none -monitor stdio
QEMU 7.1.91 monitor - type 'help' for more information
(qemu) info pci
Or they can fail, like this:
qemu-system-microblaze -M petalogix-s3adsp1800 -display none -monitor stdio
QEMU 7.1.91 monitor - type 'help' for more information
(qemu) info pci
PCI devices not supported
They fail when none of the target's machines supports PCI, i.e. when
we're using qmp_query_pci() from hw/pci/pci-stub.c.
The error is not useful, and reporting nothing makes sense, so do that
in pci-stub.c, too.
Now qmp_query_pci() can't fail anymore. Drop the dead error handling
from hmp_info_pci().

Performance improvement
Add pkt and insn to DisasContext
Many functions need information from all 3 structures, so merge
them together.
2)
Bug fix
Fix predicated assignment to .tmp and .cur
3)
Performance improvement
Add overrides for S2_asr_r_r_sat/S2_asl_r_r_sat
These functions will not be handled by idef-parser
4-11)
The final 8 patches improve change-of-flow handling.
Currently, we set the PC to a new address before exiting a TB. The
ultimate goal is to use direct block chaining. However, several steps
are needed along the way.
4)
When a packet has more than one change-of-flow (COF) instruction, only
the first one taken is considered. The runtime bookkeeping is only
needed when there is more than one COF instruction in a packet.
5, 6)
Remove PC and next_PC from the runtime state and always use a
translation-time constant. Note that next_PC is used by call instructions
to set LR and by conditional COF instructions to set the fall-through
address.
7, 8, 9)
Add helper overrides for COF instructions. In particular, we must
distinguish those that use a PC-relative address for the destination.
These are candidates for direct block chaining later.
10)
Use direct block chaining for packets that have a single PC-relative
COF instruction. Instead of generating the code while processing the
instruction, we record the effect in DisasContext and generate the code
during gen_end_tb.
11)
Use direct block chaining for tight loops. We look for TBs that end
with an endloop0 that will branch back to the TB start address.
