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.

The scenario for which --with-git= was introduced was to use a SOCKS proxy

used the git:// protocol, and it is not as important when using the
"smart HTTP" backend; for example, neither "meson subprojects download"

So remove the knob, but test for the presence of git in the configure and

in the future the GIT environment variable will be supported by Meson.

mkvenv: always pass locally-installed packages to pip

tests: Use separate virtual environment for avocado
This reverts commits
eea2d141179 ("Makefile: remove $(TESTS_PYTHON)",
2023-05-26) and
9c6692db550 ("tests: Use configure-provided pyvenv for
tests", 2023-05-18).
Right now, there is a conflict between wanting a ">=" constraint when
using a distro-provided package and wanting a "==" constraint when
installing Avocado from PyPI; this would provide the best of both worlds
in terms of resiliency for both distros that have required packages and
distros that don't.
The conflict is visible also for meson, where we would like to install
the latest 0.63.x version but also accept a distro 1.1.x version.
But it is worse for avocado, for two reasons:
1) we cannot use an "==" constraint to install avocado if the venv
includes a system avocado. The distro will package plugins that have
"==" constraints on the version that is included in the distro, and, using
"pip install avocado==88.1" on a venv that includes system packages will
result in this error:
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
avocado-framework-plugin-varianter-yaml-to-mux 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
avocado-framework-plugin-result-html 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
make[1]: Leaving directory '/home/berrange/src/virt/qemu/build'
2) we cannot use ">=" either if the venv does _not_ include a system
avocado, because that would result in the installation of v101.0 which
is the one we've just reverted.
So the idea is to encode the dependencies as an (acceptable, locked)
tuple, like this hypothetical TOML that would be committed inside
python/ and used by mkvenv.py:
[meson]
meson = { minimum = "0.63.0", install = "0.63.3", canary = "meson" }
[docs]
# 6.0 drops support for Python 3.7
sphinx = { minimum = "1.6", install = "<6.0", canary = "sphinx-build" }
sphinx_rtd_theme = { minimum = "0.5" }
[avocado]
avocado-framework = { minimum = "88.1", install = "88.1", canary = "avocado" }
Once this is implemented, it would also be possible to install avocado in
pyvenv/ using "mkvenv.py ensure", thus using the distro package on Fedora
and CentOS Stream (the only distros where it's available). But until
this is implemented, keep avocado in a separate venv. There is still the
benefit of using a single python for meson custom_targets and for sphinx.

Revert "tests/requirements.txt: bump up avocado-framework version to 101.0"
This reverts commit
ec5ffa0056389c3c10ea2de1e78366f66f4e5abc.
Bumping avocado to version 101 has two issues. First, there are problems
where Avocado is not logging of command lines or terminal output, and not
collecting Python logs outside the avocado namespace.
Second, the recent changes to Python handling mean that there is a single
virtual environment for all the build, instead of a separate one for testing.
Requiring a too-new version of avocado causes conflicts with any avocado
plugins installed on the host:
$ make check-venv

To avoid this issue, tests/requirements.txt should use a ">=" constraint
and the version of Avocado should be limited to what distros provide
in the system packages. Only Fedora has Avocado, and more specifically
version 92.0 (though 98.0 is also available as a module). As a first
step, this patch reverts the introduction of a too-new Avocado.

tcg: Widen CPUTLBEntry comparators to 64-bits
This makes CPUTLBEntry agnostic to the address size of the guest.
When 32-bit addresses are in effect, we can simply read the low
32 bits of the 64-bit field. Similarly when we need to update
the field for setting TLB_NOTDIRTY.
For TCG backends that could in theory be big-endian, but in
practice are not (arm, loongarch, riscv), use QEMU_BUILD_BUG_ON
to document and ensure this is not accidentally missed.
For s390x, which is always big-endian, use HOST_BIG_ENDIAN anyway,
to document the reason for the adjustment.
For sparc64 and ppc64, always perform a 64-bit load, and rely on
the following 32-bit comparison to ignore the high bits.
Rearrange mips and ppc if ladders for clarity.

qcow2: add discard-no-unref option
When we for example have a sparse qcow2 image and discard: unmap is enabled,
there can be a lot of fragmentation in the image after some time. Especially on VM's
that do a lot of writes/deletes.
This causes the qcow2 image to grow even over 110% of its virtual size,
because the free gaps in the image get too small to allocate new
continuous clusters. So it allocates new space at the end of the image.
Disabling discard is not an option, as discard is needed to keep the
incremental backup size as low as possible. Without discard, the
incremental backups would become large, as qemu thinks it's just dirty
blocks but it doesn't know the blocks are unneeded.
So we need to avoid fragmentation but also 'empty' the unneeded blocks in
the image to have a small incremental backup.
In addition, we also want to send the discards further down the stack, so
the underlying blocks are still discarded.
Therefor we introduce a new qcow2 option "discard-no-unref".
When setting this option to true, discards will no longer have the qcow2
driver relinquish cluster allocations. Other than that, the request is
handled as normal: All clusters in range are marked as zero, and, if
pass-discard-request is true, it is passed further down the stack.
The only difference is that the now-zero clusters are preallocated
instead of being unallocated.
This will avoid fragmentation on the qcow2 image.

parallels: Fix high_off calculation in parallels_co_check()
Don't let high_off be more than the file size even if we don't fix the
image.

parallels: Out of image offset in BAT leads to image inflation
data_end field in BDRVParallelsState is set to the biggest offset present
in BAT. If this offset is outside of the image, any further write will
create the cluster at this offset and/or the image will be truncated to
this offset on close. This is definitely not correct.
Raise an error in parallels_open() if data_end points outside the image
and it is not a check (let the check to repaire the image). Set data_end
to the end of the cluster with the last correct offset.
