Experiments show, that copy_range is not always making things faster.
So, to make experimentation simpler, let's add a parameter. Some more
perf parameters will be added soon, so here is a new struct.
For now, add new backup qmp parameter with x- prefix for the following
reasons:
- We are going to add more performance parameters, some will be
related to the whole block-copy process, some only to background
copying in backup (ignored for copy-before-write operations).
- On the other hand, we are going to use block-copy interface in other
block jobs, which will need performance options as well.. And it
should be the same structure or at least somehow related.
So, there are too much unclean things about how the interface and now
we need the new options mostly for testing. Let's keep them
experimental for a while.
In do_backup_common() new x-perf parameter handled in a way to
make further options addition simpler.
We add use-copy-range with default=true, and we'll change the default
in further patch, after moving backup to use block-copy.

The code already don't freeze base node and we try to make it prepared
for the situation when base node is changed during the operation. In
other words, block-stream doesn't own base node.
Let's introduce a new interface which should replace the current one,
which will in better relations with the code. Specifying bottom node
instead of base, and requiring it to be non-filter gives us the
following benefits:
- drop difference between above_base and base_overlay, which will be
renamed to just bottom, when old interface dropped
- clean way to work with parallel streams/commits on the same backing
chain, which otherwise become a problem when we introduce a filter
for stream job
- cleaner interface. Nobody will surprised the fact that base node may
disappear during block-stream, when there is no word about "base" in
the interface.

sys/signal.h itself.
Unconditionally including <sys/signal.h> on musl causes warnings

Since commit 1e8b5b1aa1 ("spapr: Allow memory unplug to always succeed")
trying to unplug memory from a guest that doesn't support it (eg. rhel6)
no longer generates an error like it used to. Instead, it leaves the
memory around : only a subsequent reboot or manual use of drmgr within
the guest can complete the hot-unplug sequence. A flag was added to
SpaprMachineClass so that this new behavior only applies to the default
machine type.
We can do better. CAS processes all pending hot-unplug requests. This
means that we don't really care about what the guest supports if
the hot-unplug request happens before CAS.
All guests that we care for, even old ones, set enough bits in OV5
that lead to a non-empty bitmap in spapr->ov5_cas. Use that as a
heuristic to decide if CAS has already occured or not.
Always accept unplug requests that happen before CAS since CAS will
process them. Restore the previous behavior of rejecting them after
CAS when we know that the guest doesn't support memory hot-unplug.
This behavior is suitable for all machine types : this allows to
drop the pre_6_0_memory_unplug flag.

Despite it's name it didn't actually clean-up so let us document
gdb_exit() better and use that.

AML needs Address Translation offset to describe how a bridge translates
addresses accross the bridge when using an address descriptor, and
especially on ARM, the translation offset of pio resource is usually
non zero.
Therefore, it's necessary to pass offset for pio, mmio32, mmio64 and bus
number into build_crs.

We were accidently passing RISCVHartArrayState by value instead of
pointer. The type is 824 bytes long so let's correct that and pass it by
pointer instead.

The gd_egl_refresh function, as the name suggests, is responsible for
refreshing displays when using EGL graphics with QEMU's GTK UI. This is
a perfect candidate for a function to update the refresh rate in.
Since gd_monitor_update_interval is inaccessible from the gd_egl_refresh
function, we need to expose/globalize it in the include/ui/gtk.h file.

Redefining SI prefixes is always wrong. 1s has per definition
1000ms. Remove the misnamed named constant and replace it with
a comment explaining the frequency to period conversion in two
simple steps. Now you can cancel out the unit mHz in the comment
with the implicit unit mHz in refresh_rate_millihz and see why
the implicit unit ms for update_interval remains.
