In some adhoc profiling booting Linux VMs, it's observed that ahci_irq_lower()
can be a hot path (10000+ triggers until login prompt appears). Even though the
parent device never changes, this method re-determines whether the parent device
is a PCI device or not using the rather expensive object_dynamic_cast()
function. Avoid this overhead by pushing the interrupt handling to the parent
device, essentially turning AHCIState into an "IP block".
Note that this change also frees AHCIState from the PCI dependency which wasn't
reflected in Kconfig.

Currently we hardcode the default NaN value in parts64_default_nan()
using a compile-time ifdef ladder. This is awkward for two cases:
* for single-QEMU-binary we can't hard-code target-specifics like this
* for Arm FEAT_AFP the default NaN value depends on FPCR.AH
(specifically the sign bit is different)
Add a field to float_status to specify the default NaN value; fall
back to the old ifdef behaviour if these are not set.
The default NaN value is specified by setting a uint8_t to a
pattern corresponding to the sign and upper fraction parts of
the NaN; the lower bits of the fraction are set from bit 0 of
the pattern.

IEEE 758 does not define a fixed rule for which NaN to pick as the
result if both operands of a 3-operand fused multiply-add operation
are NaNs. As a result different architectures have ended up with
different rules for propagating NaNs.
QEMU currently hardcodes the NaN propagation logic into the binary
because pickNaNMulAdd() has an ifdef ladder for different targets.
We want to make the propagation rule instead be selectable at
runtime, because:
* this will let us have multiple targets in one QEMU binary
* the Arm FEAT_AFP architectural feature includes letting
the guest select a NaN propagation rule at runtime
In this commit we add an enum for the propagation rule, the field in
float_status, and the corresponding getters and setters. We change
pickNaNMulAdd to honour this, but because all targets still leave
this field at its default 0 value, the fallback logic will pick the
rule type with the old ifdef ladder.
It's valid not to set a propagation rule if default_nan_mode is
enabled, because in that case there's no need to pick a NaN; all the
callers of pickNaNMulAdd() catch this case and skip calling it.

IEEE 758 does not define a fixed rule for what NaN to return in
the case of a fused multiply-add of inf * 0 + NaN. Different
architectures thus do different things:
* some return the default NaN
* some return the input NaN
* Arm returns the default NaN if the input NaN is quiet,
and the input NaN if it is signalling
We want to make this logic be runtime selected rather than
hardcoded into the binary, because:

Note that four architectures both use the muladd softfloat functions
and did not have a branch of the ifdef ladder to specify their
behaviour (and so were ending up with the "default" case, probably
wrongly): i386, HPPA, SH4 and Tricore. SH4 and Tricore both set
default_nan_mode, and so will never get into pickNaNMulAdd(). For
HPPA and i386 we retain the same behaviour as the old default-case,
which is to not ever return the default NaN. This might not be
correct but it is not a behaviour change.

The Big QEMU Lock (BQL) is used to provide interior mutability to Rust
code. While BqlCell performs indivisible accesses, an equivalent of
RefCell will allow the borrower to hold to the interior content for a
long time. If the BQL is dropped, another thread could come and mutate
the data from C code (Rust code would panic on borrow_mut() instead).
In order to prevent this, add a new BQL primitive that can mark
BQL-atomic sections and aborts if the BQL is dropped within them.

At present, type_register() and type_register_static() are identical,
although their documentation expects the *_static variant to accept
the Typeinfo with the strings that have the static lifetime.
However, the code implementation doesn't have any check or guarantee for
static lifetime. In fact, this is unnecessary because type_new()
duplicates all strings, thereby taking ownership of them.
Therefore, type_register() and type_register_static() are redundant, so
one of them should be removed.
Since the changes required to remove type_register() were smaller,
type_register() was replaced with type_register_static() throughout the
code base. Drop its definition, and delete the requirement about string
lifetime from the documentation.

This reverts commit 2d6cfbaf17.
The patch is supposed to be part of ARM CPU hotplug series and has not value
on its own without it. The series however is still in RFC stage and outside
of scope 9.2 release.
On top of that it introduces not needed callback that pokes directly into
CPU state without any need for that. Instead properties and AML generator
option should be used to configure static platform depended vCPU presence
state.
Drop the patch so that corrected version could be posted along with
ARM CPU hotplug series and properly reviewed in relevant context.
That also helps us to keep history cleaner with new patch being
against original code vs a string of fixups on top of current mess.
