875be287cd meson: list leftover CONFIG_* symbols
There are no config-host.mak symbols anymore that are needed in
config-host.h; the only symbols that are included in config_host_data via
the foreach loop are:

- CONFIG_DEFAULT_TARGETS, which is not used by C code.

- CONFIG_TCG and CONFIG_TCG_INTERPRETER, which are not part of config-host.mak

So, list these two symbols explicitly.

define is only necessary when building with gcc. Let's not define it when

b91b0fc163 accel: Remove HAX accelerator
HAX is deprecated since commits 73741fda6c ("MAINTAINERS: Abort
HAXM maintenance") and 90c167a1da ("docs/about/deprecated: Mark
HAXM in QEMU as deprecated"), released in v8.0.0.

Per the latest HAXM release (v7.8 [*]), the latest QEMU supported
is v7.2:

  Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0.

The next commit (https://github.com/intel/haxm/commit/da1b8ec072)
added:

  HAXM v7.8.0 is our last release and we will not accept
  pull requests or respond to issues after this.

It became very hard to build and test HAXM. Its previous
maintainers made it clear they won't help.  It doesn't seem to be
a very good use of QEMU maintainers to spend their time in a dead
project. Save our time by removing this orphan zombie code.

6db77bb2c1 meson.build: Skip C++ detection unless we're targeting Windows

4de81093f8 target/riscv: Only build KVM guest with same wordsize as host
Per Anup Patel in [*]:

 > and rv32 guest on rv32 host.
 >
 > In the future, we might support running rv32 guest on rv64
 > host but as of now we don't see a strong push for it.

Therefore, when only using the KVM accelerator it is pointless
to build qemu-system-riscv32 on a rv64 host (or qemu-system-riscv64
on a rv32 host). Restrict meson to only build the correct binary,
avoiding to waste ressources building unusable code.

'proxy' fs driver is in bad shape. Using the 'proxy' backend was already
discouraged for safety reasons before and we recommended to use the
'local' backend (preferably in conjunction with its 'mapped' security
model) instead, but now it is time to officially deprecate the 'proxy'
backend.

641b841722 accel: Re-enable WHPX cross-build on case sensitive filesystems
Since MinGW commit 395dcfdea ("rename hyper-v headers and def
files to lower case") [*], WinHvPlatform.h and WinHvEmulation.h
got respectively renamed as winhvplatform.h / winhvemulation.h.

The mingw64-headers package included in the Fedora version we
use for CI does include this commit; and meson fails to detect
these present-but-renamed headers while cross-building (on
case-sensitive filesystems).

Use the renamed header in order to detect and successfully
cross-build with the WHPX accelerator.

Note, on Windows hosts, the libraries are still named as
WinHvPlatform.dll and WinHvEmulation.dll, so we don't bother
renaming the definitions used by load_whp_dispatch_fns() in
target/i386/whpx/whpx-all.c.

To make the "-display dbus" work on Windows, implement an alternative

'ay' (WSASocketW data), and sockets are passed to the other end via
WSADuplicateSocket().

6750485bf4 target/i386: implement RDPID in TCG
RDPID corresponds to a RDMSR(TSC_AUX); however, it is unprivileged
so for user-mode emulation we must provide the value that the kernel
places in the MSR.  For Linux, it is a combination of the current CPU
and the current NUMA node, both of which can be retrieved with getcpu(2).
Also try sched_getcpu(), which might be there on the BSDs.  If there is
no portable way to retrieve the current CPU id from userspace, return 0.

RDTSCP is reimplemented as RDTSC + RDPID ECX; the differences in terms
of serializability are not relevant to QEMU.

2019cabfee meson: subprojects: replace submodules with wrap files
Compared to submodules, .wrap files have several advantages:

* option parsing and downloading is delegated to meson

* the commit is stored in a text file instead of a magic entry in the
  git tree object

* we could stop shipping external dependencies that are only used as a
  fallback, but not break compilation on platforms that lack them.
  For example it may make sense to download dtc at build time, controlled
  by --enable-download, even when building from a tarball.  Right now,
  this patch does the opposite: make-release treats dtc like libvfio-user
  (which is not stable API and therefore hasn't found its way into any
  distros) and keycodemap (which is a copylib, for better or worse).

dependency() can fall back to a wrap automatically.  However, this
is only possible for libraries that come with a .pc file, and this
is not very common for libfdt even though the upstream project in
principle provides it; it also removes the control that we provide with
--enable-fdt={system,internal}.  Therefore, the logic to pick system
vs. internal libfdt is left untouched.

--enable-fdt=git is removed; it was already a synonym for
--enable-fdt=internal.

ac4ccac740 configure: rename --enable-pypi to --enable-download, control subprojects too
The behavior of --{enable,disable}-pypi is similar to that of
-Dwrapmode={default,nodownload} respectively.  In particular,
in both cases a feature needs to be explicitly enabled for the
dependency to be downloaded.

So, use a single option to control both cases.  Now, --enable-slirp
will trigger cloning and building of libslirp if the .pc file
is not found on the machine.

50cfed80ec configure: remove --with-git= option
The scenario for which --with-git= was introduced was to use a SOCKS proxy
such as tsocks.  However, this was back in 2017 when QEMU's submodules
used the git:// protocol, and it is not as important when using the
"smart HTTP" backend; for example, neither "meson subprojects download"
nor scripts/checkpatch.pl obey the GIT environment variable.

So remove the knob, but test for the presence of git in the configure and
git-submodule.sh scripts, and suggest using --with-git-submodules=validate
+ a manual invocation of git-submodule.sh when git does not work.  Hopefully
in the future the GIT environment variable will be supported by Meson.

09a49afeae meson: Avoid implicit declaration of absent functions
While detecting a presence of a function via 'cc.links()'
gives desired result (i.e. detects whether function is present),
it also produces a warning on systems where the function is not
present (into meson-log.txt), e.g.:

  qemu.git/build/meson-private/tmph74x3p38/testfile.c:2:34: \
  warning: implicit declaration of function 'malloc_trim' [-Wimplicit-function-declaration]

And some distributions (e.g. Gentoo) parse the meson log and
consider these erroneous because it can lead to feature
misdetection (see [1]).

We can check whether given function exists via
'cc.has_function()' or whether STATX_* macros exist via
'cc.has_header_symbol()'.

98b126f5e3 qapi: add '@fdset' feature for BlockdevOptionsVirtioBlkVhostVdpa
The virtio-blk-vhost-vdpa driver in libblkio 1.3.0 supports the fd
passing through the new 'fd' property.

Since now we are using qemu_open() on '@path' if the virtio-blk driver
supports the fd passing, let's announce it.
In this way, the management layer can pass the file descriptor of an
already opened vhost-vdpa character device. This is useful especially
when the device can only be accessed with certain privileges.

Add the '@fdset' feature only when the virtio-blk-vhost-vdpa driver
in libblkio supports it.

58e48b2e72 meson: use subproject for internal libfdt
Recent dtc/libfdt can use either Make or meson as the build system.
By using a subproject, our own meson.build can remove the hard
coded list of source files.

This is also the first step towards managing downloads with .wrap
files instead of submodule.

577bdbcf85 meson: simplify logic for -Dfdt
fdt_opt == 'disabled' is going to give an error if libfdt is required
by any target, so catch that immediately.  For fdt_opt == 'enabled',
instead, do not check immediately whether the internal libfdt is present.
Instead do the check after ascertaining that libfdt is absent or too old.

b03fcd6818 meson: move -no-pie from linker to compiler
The large comment in the patch says it all; the -no-pie flag is broken and
this is why it was not included in QEMU_LDFLAGS before commit a988b4c561
("build: move remaining compiler flag tests to meson", 2023-05-18).  And
some distros made things even worse, so we have to add it to the compiler
command line.
