d7fd737bf4 scripts: Mark feature_to_c.py as non-executable to fix a build issue
Meson tries to run scripts via the shebang line if they files are
marked as executable. If "python3" is not in the $PATH, or if it
is a version that is too old, then the script execution fails.
We should make sure to run scripts via the python3 interpreter
that is used for Meson itself. For this, the files need to be marked
as non-executable, then meson will use the python3 binary that has
been used to run itself.

83629b1461 target/i386/cpu: Fix CPUID_HT exposure
When explicitly booting a multiple vcpus vm with "-cpu +ht", it gets
warning of

  warning: host doesn't support requested feature: CPUID.01H:EDX.ht [bit 28]

Make CPUID_HT as supported unconditionally can resolve the warning.
However it introduces another issue that it also expose CPUID_HT to
guest when "-cpu host/max" with only 1 vcpu. To fix this, need mark
CPUID_HT as the no_autoenable_flags.

The commit is generated by command

9acd49e29e tests/vm/basevm.py: use cmd() instead of qmp()
We don't expect failure here and need 'result' object. cmd() is better
in this case.

4e620ff48f python/machine.py: upgrade vm.cmd() method
The method is not popular in iotests, we prefer use vm.qmp() and then
check success by hand. But that's not optimal. To simplify movement to
vm.cmd() let's support same interface improvements like in vm.qmp().

684750ab4f python/qemu: rename command() to cmd()
Use a shorter name. We are going to move in iotests from qmp() to
command() where possible. But command() is longer than qmp() and don't
look better. Let's rename.

You can simply grep for '\.command(' and for 'def command(' to check
that everything is updated (command() in tests/docker/docker.py is
unrelated).

37274707f6 python: rename QEMUMonitorProtocol.cmd() to cmd_raw()
Having cmd() and command() methods in one class doesn't look good.
Rename cmd() to cmd_raw(), to show its meaning better.

We also want to rename command() to cmd() in future, so this commit is
a necessary step.

Commit a908985971 ("target/i386/seg_helper: introduce tss_set_busy",
2023-09-26) failed to use the tss_selector argument of the new function,
which was therefore unused.

This shows up as a #GP fault when booting old versions of 32-bit
Linux.
