This change removes special parsing for freeform sections and allows
them to simply be unmodified rST syntax. The existing headings in the
QAPI schema are adjusted to reflect the new paradigm.

If we remove the legacy parser, this formulation begins to fail because

Well, first I just noticed that I left a debug print in this function!
So I'll fix that.

We've got this nice vmstate-static-checker.py script that can help

This set of patches adds an automatic test of the vmstate via the
scripts/vmstate-static-checker.py script. For this we need some
reference files from an older version of QEMU. I chose to use QEMU 7.2

All other test data resides in tests/data/, so let's move the dump

In vfio_pci_igd_opregion_detect(), errp will be set when the device does
not have OpRegion or is hotplugged. This errp will be propagated to
pci_qdev_realize(), which interprets it as failure, causing unexpected
termination on devices without OpRegion like SR-IOV VFs or discrete
GPUs. Fix it by not
This commit defines TCG_TARGET_REG_BITS based on the value of
TCG_VADDR_BITS. For non-wasm hosts, TCG_VADDR_BITS matches the pointer size,
so this change preserves the original behaviour. For the wasm host, this
change enables support for 64bit guests.

This commit introduces TCG_VADDR_BITS in meson.build to explicitly define
the vaddr size. For non-wasm hosts, this is set to the value of
host_long_bits, preserving the original behaviour of the check in the target
loop. For the wasm host, it's explicitly set to 64 to enable support for
64bit guest
TCI's tcg_out_call stores "func" and "cif" as tcg_target_ulong in the TB

host, tcg_target_ulong differs from the pointer size so this change ensures
