We originally naively treated expansion as safe because we expected
each new CPU/thread to appear in order. However the -M raspi2 model
triggered a case where a new high cpu_index thread started executing
just before a smaller one.
Clean this up by converting the GArray into the simpler GPtrArray and
then holding a lock for the expansion.

We used to rely on QEMU_CFLAGS to expose the debug flags but now this
is synthesised by meson and only available to the main build. Add our
own flags if we detect the build has been enabled with
CONFIG_DEBUG_TCG (which is the default for --enable-debug anyway).

The s390x EXecute instruction is a bit weird as we synthesis the
executed instruction from what we have stored in memory. This missed
the plugin instrumentation.
Work around this with a special helper to inform the rest of the
translator about the instruction so things stay consistent.

The avocado test
tests/avocado/boot_linux_console.py:BootLinuxConsole.test_arm_raspi2_initrd
finishes with
exec_command(self, 'halt')
# Wait for VM to shut down gracefully
self.vm.wait()
In theory this should be fine. In practice it runs into two bugs:
* when the test calls self.vm.wait() Avocado closes the socket
connection to the guest serial console immediately, so the
avocado logs don't have the last part of the guest output:
https://gitlab.com/qemu-project/qemu/-/issues/1265
* when the socket is closed, a bug in the QEMU socket chardev
means that it loses any data that the guest UART has not
yet consumed. This means that the guest doesn't always read
the full 'halt' command string, so the test intermittently
fails with a timeout:
https://gitlab.com/qemu-project/qemu/-/issues/1264
Work around both of these by waiting for the guest to print the
string that means it has completed the shutdown process. This fixes
a very long standing intermittent failure in this test.

Changes to the build files are a bit special in that they usually go

is the root of everything a developer is likely to do we should at

The nvme-io_uring driver expects a character special file such as
/dev/ng0n1. Follow the convention of having a "filename" option when a
regular file is expected, and a "path" option otherwise.
This makes io_uring the only libblkio-based driver with a "filename"
option, as it accepts a regular file (even though it can also take a
block special file).

Some libblkio drivers may be able to work with regular files (e.g.,
io_uring) or otherwise resizable devices. Conservatively set
BlockDriver::has_variable_length to true to ensure bdrv_nb_sectors()
always gives up-to-date results.
Also implement BlockDriver::bdrv_co_truncate for the case where no
preallocation is needed and the device already has a size compatible
with what was requested.
