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.

The fid instruction (Floating-Point Identify) puts the FPU model and
revision into the Status Register. Since those values shouldn't be 0,
store values there which a PCX-L2 (for 32-bit) or a PCX-W2 (for 64-bit)
would return. Noticed while trying to install MPE/iX.

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().

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().

1)
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.
12-21)
Instruction definition parser (idef-parser) from rev.ng
Parses the instruction semantics and generates TCG

Make certain helper functions non-static, making them available outside
genptr.c. These functions are required by code generated by the
idef-parser.
This commit also makes some functions in op_helper.c non-static in order
to avoid having them marked as unused when using the idef-parser
generated code.

Direct block chaining is documented here
https://qemu.readthedocs.io/en/latest/devel/tcg.html#direct-block-chaining
Hexagon inner loops end with the endloop0 instruction
To go back to the beginning of the loop, this instructions writes to PC
from register SA0 (start address 0). To use direct block chaining, we
have to assign PC with a constant value. So, we specialize the code
generation when the start of the translation block is equal to SA0.
When this is the case, we defer the compare/branch from endloop0 to
gen_end_tb. When this is done, we can assign the start address of the TB
to PC.

Direct block chaining is documented here
https://qemu.readthedocs.io/en/latest/devel/tcg.html#direct-block-chaining
Recall that Hexagon allows packets with multiple jumps where only the
first one with a true predicate will actually jump. We can use
tcg_gen_goto_tb/tcg_gen_exit_tb when the packet contains a single
PC-relative branch or jump. If not, we use tcg_gen_lookup_and_goto_ptr.
We add the following to DisasContext in order to delay the branching
until the end of packet commit (in gen_end_tb)
branch_cond
The TCGCond condition under which the branch is taken
When branch_cond == TCG_COND_NEVER, there isn't a single
direct branch in this packet.
When branch_cond != TCG_COND_ALWAYS, the value is in
hex_branch_taken
branch_dest
The destination of the branch

When a packet has more than one change-of-flow instruction, only the first
one to branch is considered. We use the branch_taken variable to keep
track of this.
However, when there is a single cof instruction, we don't need the same
amount of bookkeeping.
We add the pkt_has_multi_cof member to the Packet structure, and pass this
information to the needed functions.
When there is a generated helper function with cof, the generator will
pass this pkt_has_multi_cof as a runtime value.

Here are example instructions with a predicated .tmp/.cur assignment
if (p1) v12.tmp = vmem(r7 + #0)
if (p0) v12.cur = vmem(r9 + #0)
The .tmp/.cur indicates that references to v12 in the same packet
take the result of the load. However, when the predicate is false,
the value at the start of the packet should be used. After the packet
commits, the .tmp value is dropped, but the .cur value is maintained.
To fix this bug, we preload the original value from the HVX register
into the temporary used for the result.

In particular, the generated functions previously took all 3 as arguments
