Ho hum. Let a feature loose on users and they find bugs. Mark noticed
that the wrong value was being picked up for VL when SVE is disabled.
I had run the same test but failed to notice the vector length wasn't

The aim of this series is to reorganize bdrv_try_set_aio_context
and drop BDS ->set_aio_context and ->can_set_aio_ctx callbacks in
favour of a new one, ->change_aio_ctx.
More informations in patch 3 (which is also RFC, due to the doubts
I have with AioContext locks).
Patch 1 just add assertions

If we don't need to emulate any target, we certainly don't need TCG.
This should also help to compile again with
".../configure --enable-tools --disable-system --disable-user"
on systems that do not have a TCG backend.
Some systems have /proc/device-tree/cpus/../clock-frequency. However,
this is not the expected path for a CPU device tree directory.

With semihosting_get_arg, we already have a check vs argc, so
there's no point replicating it -- just check the result vs NULL.
Merge copy_argn_to_target into its caller.

Always log the assert locally. Do not report_fault, but
instead include the fact of the fault in the assertion.
Don't bother freeing allocated strings before the abort().

The UHI specification does not have an EFAULT value,
and further specifies that "undefined UHI operations
should not return control to the target".
So, log the error and abort.
