In commit b0fcc6fc7f ("build: rebuild build.ninja using
"meson setup --reconfigure"", 2023-05-19) I changed the build.ninja
rule in the Makefile to use "meson setup" so that the Makefile would
pick up a changed path to the meson binary.
However, there was a reason why build.ninja was rebuilt using $(NINJA)
itself. Namely, ninja has its own cache of file modification times,
and if it does not know about the modification that was done outside
its control, it will *also* try to regenerate build.ninja. This can be
simply by running "make" on a fresh tree immediately after "configure";
that will trigger an unnecessary meson run.
So, apply a refinement to the rule in order to cover both cases:
- track the meson binary that was used (and that is embedded in
build.ninja's reconfigure rules); to do this, write build.ninja.stamp
right after executing meson successfully
- if it changed, force usage of "$(MESON) setup --reconfigure" to
update the path in the reconfigure rule
- if it didn't change, use "$(NINJA) build.ninja" just like before
commit b0fcc6fc7f.

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.

Run 'make distclean' in a tree, and GNUmakefile is removed.
But, GNUmakefile is where we change directory to build.
Run 'make distclean' or 'make clean' again, and Makefile applies
the clean actions, such as this one, at the top level of the tree.
For example, it removes the .d source files in 'meson/test cases/d/*/*.d'.
find . \( -name '*.so' -o -name '*.dll' -o \
-name '*.[oda]' -o -name '*.gcno' \) -type f \
! -path ./roms/edk2/ArmPkg/Library/GccLto/liblto-aarch64.a \
! -path ./roms/edk2/ArmPkg/Library/GccLto/liblto-arm.a \
-exec rm {} +
To fix, remove clean and distclean from UNCHECKED_GOALS, so those targets
are "checked", meaning that configure must be run before make. However,
the check action does not trigger, because clean does not depend on
config-host.mak, so change the action to simply throw an error.

Meson supports an "uninstall", so we can easily allow it to work by
not suppressing the forwarding of it from Make to meson.
We originally suppressed this because Meson's 'uninstall' has a hole
in it: it will remove everything that is installed by a mechanism
meson knows about, but not things installed by "custom install
scripts", and there is no "custom uninstall script" mechanism.
For QEMU, though, the only thing that was being installed by a custom
install script was the LC_MESSAGES files handled by Meson's i18n
module, and that code was fixed in Meson commit 487d45c1e5bfff0fbdb4,
which is present in Meson 0.60.0 and later. Since we already require
a Meson version newer than that, we're now safe to enable
'uninstall', as it will now correctly uninstall everything that was
installed.

Developers often run QEMU without installing. The bundle mechanism
allows to look up files which should be present in installation even in
such a situation.
It is a general mechanism and can find any files in the installation
tree. The build tree will have a new directory, qemu-bundle, to
represent what files the installation tree would have for reference by
the executables.
Note that it abandons compatibility with Windows older than 8. The
extended support for the prior version, 7 ended more than 2 years ago,
and it is unlikely that someone would like to run the latest QEMU on
such an old system.

This introduces
https://gitlab.com/libvirt/libvirt-ci
as a git submodule at tests/lcitool/libvirt-ci
The 'lcitool' program within this submodule will be used to
automatically generate build environment manifests from a definition
of requirements in tests/lcitool/projects/qemu.yml
It will ultimately be capable of generating
- Dockerfiles
- Package lists for installation in VMs
- Variables for configuring Cirrus CI environments
When a new build pre-requisite is needed for QEMU, if this package
is not currently known to libvirt-ci, it must first be added to the
'mappings.yml' file in the above git repo.
Then the submodule can be updated and the build pre-requisite added
to the tests/lcitool/projects/qemu.yml file. Now all the build env
manifests can be re-generated using 'make lcitool-refresh'
This ensures that when a new build pre-requisite is introduced, it
is added to all the different OS containers, VMs and Cirrus CI
environments consistently.
It also facilitates the addition of containers targetting new distros
or updating existing containers to new versions of the same distro,
where packages might have been renamed.

This patch fixes actually two issues with 'make cscope'.
Firstly, it fixes the command for MacOS "find" command as MacOS will append the
full path of "$(SRC_PATH)/" before each found entry, then after the final "./"
replacement trick it'll look like (e.g., "qapi/qmp-dispatch.c"):
/qapi/qmp-dispatch.c
Which will point to the root directory instead.
Fix it by simply remove the "/" in "$(SRC_PATH)/" of "find-src-path", then
it'll work for at least both Linux and MacOS.
The other OS-independent issue is to start proactively ignoring soft links when
generating tags, otherwise by default on master branch we'll see this error
when "make cscope":
cscope: cannot find file subprojects/libvhost-user/include/atomic.h
This patch should fix the two issues altogether.

We are generating a lot of target-specific defines in the *-config-devices.h

to very subtle bugs since a "#ifdef CONFIG_SOMETHING" is not working there
as expected. To avoid these issues, we are already poisoning many of the
macros in include/exec/poison.h - but it's cumbersome to maintain this
list manually. Thus let's generate an additional list of poisoned macros
automatically from the current config switches - this should give us a
much better test coverage via the different CI configurations.
Note that CONFIG_TCG (which is also defined in config-host.h) and
CONFIG_USER_ONLY are special, so we have to filter these out.

Replace the --enable-git-update and --disable-git-update configure params
with the param --with-git-submodules=(update|validate|ignore) to
allow 3 options for building from a git repo.
This is needed because downstream packagers, e.g. Debian, Ubuntu, etc,
also keep the source code in git, but do not want to enable the
'git_update' mode; with the current code, that's not possible even
if the downstream package specifies --disable-git-update.
The previous parameters are deprecated but still available; the
--enable-git-update parameter maps to --with-git-submodules=update and
--disable-git-update parameter maps to --with-git-submodules=validate.
The configure script behavior is slightly modified, where previously
the dtc, capstone, and slirp submodules were not validated when
--disable-git-update was specified (but were updated with git-update
enabled), now they are validated when using --with-git-submodules=validate
and are only ignored when using --with-git-submodules=ignore.

The rules to build Makefile.mtest are suffering from the "tunnel vision"

rebuilt before creating Makefile.mtest.
To fix this, separate the ninja invocation into the "regenerate build
files" phase and the QEMU build phase. Sentinel files such as
meson-private/coredata.dat or build.ninja are used to figure out the
phases that haven't run yet; however, because those files' timestamps
are not guaranteed to be touched, the usual makefile stamp-file trick
is used on top.

Now that the build is done entirely by Meson, there is no need
to keep the Makefile conversion. Instead, we can ask Ninja about
the targets it exposes and forward them.
The main advantages are, from smallest to largest:
- reducing the possible namespace pollution within the Makefile
- removal of a relatively large Python program
- faster build because parsing Makefile.ninja is slower than
parsing build.ninja; and faster build after Meson runs because
we do not have to generate Makefile.ninja.
- tracking of command lines, which provides more accurate rebuilds
In addition the change removes the requirement for GNU make 3.82, which
was annoying on Mac, and avoids bugs on Windows due to ninjatool not
knowing how to convert Windows escapes to POSIX escapes.
