Currently we mishandle the --semihosting-config option if the
user specifies it on the command line more than once. For
example with:
--semihosting-config target=gdb --semihosting-config arg=foo,arg=bar
the function qemu_semihosting_config_options() is called twice, once
for each argument. But that function expects to be called only once,
and it always unconditionally sets the semihosting.enabled,
semihost_chardev and semihosting.target variables. This means that
if any of those options were set anywhere except the last
--semihosting-config option on the command line, those settings are
ignored. In the example above, 'target=gdb' in the first option is
overridden by an implied default 'target=auto' in the second.
The QemuOptsList machinery has a flag for handling this kind of
"option group is setting global state": by setting
.merge_lists = true;
we make the machinery merge all the --semihosting-config arguments
the user passes into a single set of options and call our
qemu_semihosting_config_options() just once.

In two places in gdbstub.c we look at gdbserver_state.init to decide
whether we're going to do a semihosting syscall via the gdb remote
protocol:
* when setting up, if the user didn't explicitly select either
native semihosting or gdb semihosting, we autoselect, with the
intended behaviour "use gdb if gdb is connected"
* when the semihosting layer attempts to do a syscall via gdb, we
silently ignore it if the gdbstub wasn't actually set up
However, if the user's commandline sets up the gdbstub but tells QEMU
to start rather than waiting for a GDB to connect (eg using '-s' but
not '-S'), then we will have gdbserver_state.init true but no actual
connection; an attempt to use gdb syscalls will then crash because we
try to use gdbserver_state.c_cpu when it hasn't been set up:
#0 0x00007ffff6803ba8 in qemu_cpu_kick (cpu=0x0) at ../../softmmu/cpus.c:457

You can probably also get into this state via some odd
corner cases involving connecting a GDB and then telling it
to detach from all the vCPUs.
Abstract out the test into a new gdb_attached() function
which returns true only if there's actually a GDB connected
to the debug stub and attached to at least one vCPU.

Move the computation from gen_swstep_exception into a helper.
This fixes a bug when:
- MDSCR_EL1.KDE == 1 to enable debug exceptions within EL_D itself
- we singlestep an ERET from EL_D to some lower EL
Previously we were computing 'same el' based on the EL which
executed the ERET instruction, whereas it ought to be computed
based on the EL to which ERET returned. This happens naturally
with the new helper, which runs after EL has been changed.

When running a 32-bit guest, with a e64 vmv.v.x and vl_eq_vlmax set to
true the `tcg_debug_assert(vece <= MO_32)` will be triggered inside
tcg_gen_gvec_dup_i32().
This patch checks that condition and instead uses tcg_gen_gvec_dup_i64()
is required.

Currently vhost-user-scsi driver doesn't allow to change
the configuration space of virtio_scsi, while vhost-user-blk
support that, so here we set the flag in vhost-user-blk driver
and unset it in vhost-user-scsi.

Variable `vdev` in `struct vhost_dev` will not be ready

This ensures that the VIOT ACPI table output is always stable for a given PCI
topology by ensuring that entries are ordered according to min_bus.

Perform the generation of the VIOT ACPI table in 2 separate passes: the first pass
enumerates all of the PCI host bridges and adds the min_bus and max_bus information
to an array.
Once this is done the VIOT table header is generated using the size of the array
to calculate the node count, which means it is no longer necessary to use a
sub-array to hold the PCI host bridge range information along with viommu_off.
Finally the PCI host bridge array is iterated again to add the required entries
to the final VIOT ACPI table.
