At the moment, we look for just "python3" and "python", which is good
enough almost all of the time. But ... if you are on a platform that
uses an older Python by default and only offers a newer Python as an
option, you'll have to specify --python=/usr/bin/foo every time.
We can be kind and instead make a cursory attempt to locate a suitable
Python binary ourselves, looking for the remaining well-known binaries.
This configure loop will prefer, in order:
1. Whatever is specified in $PYTHON
2. python3
3. python
4. python3.11 down through python3.6
Notes:
- Python virtual environment provides binaries for "python3", "python",
and whichever version you used to create the venv,
e.g. "python3.8". If configure is invoked from inside of a venv, this
configure loop will not "break out" of that venv unless that venv is
created using an explicitly non-suitable version of Python that we
cannot use.
- In the event that no suitable python is found, the first python found
is the version used to generate the human-readable error message.
- The error message isn't printed right away to allow later
configuration code to pick up an explicitly configured python.

If neither --python nor --meson are specified, Meson's generated
build.ninja will invoke Python script using the interpreter *that Meson
itself is running under*; not the one identified by configure.
This is only an issue if Meson's Python interpreter is not "the first
one in the path", which is the one that is used if --python is not
specified. A common case where this happen is when the "python3" binary
comes from a virtual environment but Meson is not installed (with pip)
in the virtual environment. In this case (presumably) whoever set up
the venv wanted to use the venv's Python interpreter to build QEMU,
while Meson might use a different one, for example an enterprise
distro's older runtime.
So, detect whether a virtual environment is setup, and if the virtual
environment does not have Meson, use the meson submodule. Meson will
then run under the virtual environment's Python interpreter.

Anthony Perard recently reported some problems with Clang v6.0 from
Ubuntu Bionic (with regards to the -Wmissing-braces configure test).
Since we're not officially supporting that version of Ubuntu anymore,
we should better bump our minimum version check in the configure script
instead of using our time to fix problems of unsupported compilers.
According to repology.org, our supported distros ship these versions
of Clang (looking at the highest version only):
Fedora 36: 14.0.5
CentOS 8 (RHEL-8): 12.0.1
Debian 11: 13.0.1
OpenSUSE Leap 15.4: 13.0.1
Ubuntu LTS 20.04: 12.0.0
FreeBSD Ports: 15.0.7
NetBSD pkgsrc: 15.0.7
Homebrew: 15.0.7
MSYS2 mingw: 15.0.7
Haiku ports: 12.0.1
While it seems like we could update to v12.0.0 from that point of view,
the default version on Ubuntu 20.04 is still v10.0, and we use that for
our CI tests based via the tests/docker/dockerfiles/ubuntu2004.docker
file.
Thus let's make v10.0 our minimum version now (which corresponds to
Apple Clang version v12.0). The -Wmissing-braces check can then be
removed, too, since both our minimum GCC and our minimum Clang version
now handle this correctly.

We've been very gradually adding G_GNUC_PRINTF annotations

certain malformed printf strings, or cases where we pass
user data as the printf format which is a potential security
flaw.
Given the inherant memory corruption danger in use of format
strings vs mis-matched variadic arguments, it is worth applying
G_GNUC_PRINTF to all functions using printf, even if we know
they are safe.
The compilers can reasonably reliably identify such places
with the -Wsuggest-attribute=format / -Wmissing-format-attribute

```

In the probe_target_compiler function, the 'break'
command is used incorrectly. There are no lexically
enclosing loops associated with that break command which
is an unspecfied behaviour in the POSIX standard.
The dash shell implementation aborts the currently executing
loop, in this case, causing the rest of the logic for the loop
in line 2490 to be skipped, which means no Makefiles are
generated for the tcg target tests.

When determining the endiandness of the target architecture we're
building for a small program is compiled, which in an obfuscated
way declares two strings. Then, we look which string is in
correct order (using strings binary) and deduct the endiandness.
But using the strings binary is problematic, because it's part of
toolchain (strings is just a symlink to
x86_64-pc-linux-gnu-strings or llvm-strings). And when
(cross-)compiling, it requires users to set the symlink to the
correct toolchain.
Fortunately, we have a better alternative anyways. We can mimic
what compiler.h is already doing: comparing __BYTE_ORDER__
against values for little/big endiandness.

Since QEMU 7.1 we don't support Ubuntu 18.04 anymore, so the last big
important Linux distro that did not have a pre-packaged libslirp has
been dismissed. All other major distros seem to have a libslirp package
in their distribution already - according to repology.org:
Fedora 35: 4.6.1
CentOS 8 (RHEL-8): 4.4.0
Debian 11: 4.4.0
OpenSUSE Leap 15.3: 4.3.1
Ubuntu LTS 20.04: 4.1.0
FreeBSD Ports: 4.7.0
NetBSD pkgsrc: 4.7.0
Homebrew: 4.7.0
MSYS2 mingw: 4.7.0
The only one that was still missing a libslirp package is OpenBSD - but
the next version (OpenBSD 7.2 which will be shipped in October) is going
to include a libslirp package. Since QEMU 7.2 will be published after
OpenBSD 7.2, we should be fine there, too.
So there is no real urgent need for keeping the slirp submodule in
the QEMU tree anymore. Thus let's drop the slirp submodule now and
rely on the libslirp packages from the distributions instead.

A Linux headers update to v6.0-rc switches some definitions from GNU
'zero-length-array' extension to the C-standard-defined flexible array
member. e.g.
struct kvm_msrs {
__u32 nmsrs; /* number of msrs in entries */
__u32 pad;
- struct kvm_msr_entry entries[0];
+ struct kvm_msr_entry entries[];
};
Those (unlike the GNU zero-length-array) have some extra restrictions like
'this must be put at the end of a struct', which clang build would complain
about. e.g. the current code
struct {
struct kvm_msrs info;
struct kvm_msr_entry entries[1];
} msr_data = { }
generates the warning like:
target/i386/kvm/kvm.c:2868:25: error: field 'info' with variable sized
type 'struct kvm_msrs' not at the end of a struct or class is a GNU
extension [-Werror,-Wgnu-variable-sized-type-not-at-end]
struct kvm_msrs info;
^
In fact, the variable length 'entries[]' field in 'info' is zero-sized in
GNU defined semantics, which can give predictable offset for 'entries[1]'
in local msr_data. The local defined struct is just there to force a stack
allocation large enough for 1 kvm_msr_entry, a clever trick but requires to
turn off this clang warning.

that would rely on -msmall-data.

Configure is trying to fall back on cross compilers for targets that
can have bi-arch or bi-endian toolchains, but there are many corner
cases where just checking the name can go wrong. For example, the RHEL
ppc64le compiler is bi-arch and bi-endian, but multilibs are disabled.
Therefore it cannot be used to build 32-bit hosted binaries like the
linux-user TCG tests.
Trying the cross compiler first also does not work, and an example for
this is also ppc64le. The powerpc64-linux-gnu-gcc binary from the
cross-gcc package is theoretically multilib-friendly, but it cannot
find the CRT files on a ppc64le host, because they are not in the .../le
multilib subdirectory.
This can be fixed by testing both the native compiler and the cross
compiler, and proceeding with the first one that works. To do this,
move the compiler usability check from the tests/tcg snippet to inside
probe_target_compiler and, while at it, restrict the softmmu emulation
target to basically a test for the presence of libgcc.

[Changed submodule URL to QEMU's libvfio-user mirror on GitLab. The QEMU
project mirrors its dependencies so that it can provide full source code
even in the event that its dependencies become unavailable. Note that
the mirror repo is manually updated, so please contact me to make newer
libvfio-user commits available. If I become a bottleneck we can set up a
cronjob.
Updated scripts/meson-buildoptions.sh to match the meson_options.txt
change. Failure to do so can result in scripts/meson-buildoptions.sh
being modified by the build system later on and you end up with a dirty
working tree.

The move from tests/tcg/configure.sh started enabling the container image
for xtensa-linux-user, which fails because the compiler does not have
the full set of headers. The cause is the "xtensa*-softmmu)" case
in tests/tcg/configure.sh which became just "xtensa*)" in the new
probe_target_compiler shell function. Look out for xtensa*-linux-user
and do not configure it.

Also in preparation for handling more binaries from the cross binutils,
support an option --cross-prefix-ARCH. All cross_cc_* defaults are
replaced with cross_prefix_*; the cross_cc_* fallbacks are extended
to the cross-compilation prefix, but the compiler fallbacks remain
as well. This way, for example, --cross-cc-arm=arm-linux-gnueabihf-clang
also applies to armeb binaries.

tests/tcg/configure.sh has a complicated story.
In the beginning its code ran as part of the creation of config-target.mak
files, and that is where it placed the information on the target compiler.
However, probing for the buildability of TCG tests required multiple
inclusions of config-target.mak in the _main_ Makefile (not in
Makefile.target, which took care of building the QEMU executables in
the pre-Meson era), which polluted the namespace.
Thus, it was moved to a separate directory. It created small config-*.mak
files in $(BUILD_DIR)/tests/tcg. Those were also included multiple
times, but at least they were small and manageable; this was also an
important step in disentangling the TCG tests from Makefile.target.
Since then, Meson has allowed the configure script to go on a diet.
A few compilation tests survive (mostly for sanitizers) but these days
it mostly takes care of command line parsing, looking for tools, and
setting up the environment for Meson to do its stuff.
It's time to extend configure with the capability to build for more
than just one target: not just tests, but also firmware. As a first
step, integrate all the logic to find cross compilers in the configure
script, and move tests/tcg/configure.sh back there (though as a
separate loop, not integrated in the one that generates target
configurations for Meson).
tests/tcg is actually very close to being buildable as a standalone
project, so I actually expect the compiler tests to move back to
tests/tcg, as a "configure" script of sorts which would run at Make
time after the docker images are built. The GCC tree has a similar idea
of doing only bare-bones tree-wide configuration and leaving the rest
for Make time.

This is useful because pc-bios/meson.build already has a list of all ROM
files, and thus does not need to use wildcards. The problems with
wildcards are mentioned above the definition of the LINKS variable,
but then the recommendation is disattended.
