The float-access functions stfl_*, stfq*, ldfl* and ldfq* are now
unused; remove them. (Accesses to float64 and float32 types can be
made with the ldl/stl/ldq/stq functions, as float64 and float32 are

We used to make a distinction between 'float64'/'float32' types and
the 'uint64_t'/'uint32_t' types, requiring special conversion
operations to go between them. We've now dropped this distinction as
unnecessary, and the 'float*' types remain primarily for
documentation purposes when used in places like the function
prototypes of TCG helper functions.
This means that there's no need for a special gdb_get_float64()
function to write a float64 value to the GDB protocol buffer; we can
just use gdb_get_reg64().
Similarly, for reading a value out of the GDB buffer into a float64
we can use ldq_p() and need not use ldfq_p().

The recommended use of qemu error api assumes returning status together
with setting errp and avoid void functions with errp parameter. Let's
improve bdrv_append and some friends to reduce error-propagation
overhead in further patches.
Choose int return status, because bdrv_replace_node_common() has call
to bdrv_check_update_perm(), which reports int status, which seems
correct to propagate.

Bitmap's source persistence is transported over the migration stream and
the destination mirrors it. In some cases the destination might want to
persist bitmaps which are not persistent on the source (e.g. the result
of merging bitmaps from a number of layers on the source when migrating
into a squashed image) but currently it would need to create another set
of persistent bitmaps and merge them.
This patch adds a 'transform' property to the alias map which allows
overriding the persistence of migrated bitmaps both on the source and
destination sides.

Our default of a backlog of 1 connection is rather puny; it gets in
the way when we are explicitly allowing multiple clients (such as
qemu-nbd -e N [--shared], or nbd-server-start with its default
"max-connections":0 for unlimited), but is even a problem when we
stick to qemu-nbd's default of only 1 active client but use -t
[--persistent] where a second client can start using the server once
the first finishes. While the effects are less noticeable on TCP
sockets (since the client can poll() to learn when the server is ready
again), it is definitely observable on Unix sockets, where on Linux, a
client will fail with EAGAIN and no recourse but to sleep an arbitrary
amount of time before retrying if the server backlog is already full.
Since QMP nbd-server-start is always persistent, it now always
requests a backlog of SOMAXCONN; meanwhile, qemu-nbd will request
SOMAXCONN if persistent, otherwise its backlog should be based on the
expected number of clients.
See https://bugzilla.redhat.com/1925045 for a demonstration of where
our low backlog prevents libnbd from connecting as many parallel
clients as it wants.

functions were also missing a decode for the 68060 M68K_CR_CAAR CR register.
Added missing defines, and respective decodes for all three CR registers to
the helpers.
Although this patch defines them, the implementation is empty in this patch
and these registers will result in a cpu abort - which is the default prior
to this patch.
This patch aims to reach full coverage of all CR registers within the helpers.

Add more detailed comments to each case of m68k_move_to/from helpers to list
the supported CPUs for that CR as they were wrong in some cases, and
missing some cpu classes in other cases.

The m680XX_cpu_initfn functions have been rearranged to cascade starting from
the base 68000, so that the 68010 then inherits from this, and so on until the
68060.
This makes it simpler to track features since in most cases the m68k were
product enhancements on each other, with only a few instructions being retired.
Because each cpu class inherits the previous CPU class, then for example
the 68020 also has the feature 68010, and 68000 and so on upto the 68060.
- Added 68010 cpu class, and moved correct features into 68000/68010.
- Added m68k_unset_feature to allow removing a feature in the inheritence

Improvement in comments for the instantiation functions.
This is to highlight what each cpu class, in the 68000 series, contains
in terms of instructions/features.

When working with performance monitoring counters, we look at
MDCR_EL2.HPMN as part of the check whether a counter is enabled. This
check fails, because MDCR_EL2.HPMN is reset to 0, meaning that no
counters are "enabled" for < EL2.
That's in violation of the Arm specification, which states that
> On a Warm reset, this field [MDCR_EL2.HPMN] resets to the value in
> PMCR_EL0.N
That's also what a comment in the code acknowledges, but the necessary
adjustment seems to have been forgotten when support for more counters
was added.
This change fixes the issue by setting the reset value to PMCR.N, which
is four.

nvme_ns_realize passes errp to nvme_register_namespaces, but then try to
prepend errp with local_err.
Just remove the local_err and use errp directly.

Moving namespace registration to the nvme-ns realization function had
the unintended side-effect of breaking legacy namespace registration.
