See the following QEMU commits for reference:
0c5f3dcbb2 ("configure: add --enable-pypi and --disable-pypi")
ac4ccac740 ("configure: rename --enable-pypi to --enable-download, control subprojects too")
6f3ae23b29 ("configure: remove --with-git-submodules=") removed
The last one removed the option and the closest thing to
git-submodule=ignore is using disable-download. Which will then just
verify that the submodules are present.
Building now will require running either
* Running 'meson subprojects download' in the qemu submodule first.
* Using --enable-download, but then the submodules would be downloaded
for each build (if not already downloaded in the submodule first)
and it's just a bit too surprising if downloads happen during build.
The disable-download option will also disable automatic downloading of
missing Python modules from PyPI. Hopefully, it's enough to add them
as Debian build dependencies when required.

virtiofsd is no longer part of QEMU 8.0. It got replaced by a separate
implementation written in Rust, which will be its own package.

Commit d03e1b3 ("update submodule and patches to 7.2.0") argued that
slirp is not explicitly supported in PVE, but that is not true. In
qemu-server, user networking is supported (via CLI/API) when no bridge
is set on a virtual NIC. So slirp needs to stay to keep such NICs
working.

This version string can be queried with $BINARY --version as well as
the query-version QMP command.
Useful for qemu-server to be able to report the running QEMU version
exactly. Could also be used to version guard against features as an
alternative to the query-proxmox-support QMP command.

Lots of patches touched and some slight changes to the build process
since QEMU switched to meson as their build system. Functionality-wise
very little rebasing required.
New patches introduced:
* pve/0058: to fix VMA backups and clean up some code in general with
new 5.2 features now available to us (namely coroutine-enabled QMP).
* extra/0002: don't build man pages for guest agent when disabled
* extra/0003: fix live-migration with hugepages
* 0017 and 0018 are adjusted to fix snapshot abort and improve
snap performance a bit

jemalloc does not play nice with our Rust library (proxmox-backup-qemu),
specifically it never releases memory allocated from Rust to the OS.
This leads to a problem with larger caches (e.g. for the PBS block driver).
It appears to be related to this GitHub issue:
https://github.com/jemalloc/jemalloc/issues/1398
The background_thread solution seems weirdly hacky, so let's disable
jemalloc entirely for now.

located at /usr/share/kvm/recognized-CPUID-flags-x86_64
It's a simple one flag per line list of all flags the build of QEMU
can understand for x86_64 CPUs.
It will be used in qemu-server for the custom CPU model feature.
For now, only x86_64 is implemented, since aarch64 doesn't print any flags when
called this way.

I don't know why fdt, Flat Device Tree, is disabled,
but that disabling blocks building e.g. qemu-system-aarch64.
It stops the build and yields this:
ERROR: fdt disabled but some requested targets require it.
You can turn off fdt only if you also disable all the system
emulation targets which need it
(by specifying a cut down --target-list).

This allows adding additional debian packages on pve hosts
which depends on a qemu binary being installed.
The following install paths were tested:
* install of proxmox-ve on debian systems with standard package
set: works as expected
* install of proxmox-ve on debian having the debian qemu package
installed: refused by the package manager as expected, until
qemu, qemu-system-x86, libspice-server1 are deinstalled
* manual install of qemu-system-x86 after proxmox-ve
is installed: refused by the package manager as expected, until
libspice-server1 is installed. If libspice-server1 is installed
then proxmox-ve is deinstalled.
* install of packages depending on qemu-system-x86
having proxmox-ve installed: thoses packages are installed as
expected, no conflict
