Let's remember the value (successfully) set via s390_set_max_pagesize().
This will be helpful to reject hotplugged memory devices that would exceed
this initially set page size.
Handle it just like how we handle s390_get_memory_limit(), storing it in
the machine, and moving the handling to machine code.

Let's avoid checking for the maxram_size, and instead rely on the memory
limit determined in s390_memory_init(), that might be larger than
maxram_size, for example due to alignment purposes.
This check now correctly mimics what the kernel will check in
kvm_s390_pv_set_aside(), whereby a VM <= 2 GiB VM would end up using
a segment type ASCE.

Nowadays, it feels more natural to have that code located in
s390_memory_init(), where we also have direct access to the machine
object.
While at it, use the actual RAM size, not the maximum RAM size which
cannot currently be reached without support for any memory devices.
Consequently update s390_pv_vm_try_disable_async() to rely on the RAM size
as well, to avoid temporary issues while we further rework that
handling.
set_memory_limit() is temporary, we'll merge it with
s390_set_memory_limit() next.

Let's generalize, abstracting the virtio bits. diag500 is now a generic
hypercall to handle QEMU/KVM specific things. Explicitly specify all
already defined subcodes, including legacy ones (so we know what we can
use for new hypercalls).
Move the PGM_SPECIFICATION injection into the renamed function
handle_diag_500(), so we can turn it into a void function.
We'll rename the files separately, so git properly detects the rename.

Convert the s390 CPU to the Resettable interface. This is slightly
more involved than the other CPU types were (see commits
9130cade5fc22..d66e64dd006df) because S390 has its own set of
different kinds of reset with different behaviours that it needs to
trigger.
We handle this by adding these reset types to the Resettable
ResetType enum. Now instead of having an underlying implementation
of reset that is s390-specific and which might be called either
directly or via the DeviceClass::reset method, we can implement only
the Resettable hold phase method, and have the places that need to
trigger an s390-specific reset type do so by calling
resettable_reset().
The other option would have been to smuggle in the s390 reset
type via, for instance, a field in the CPU state that we set
in s390_do_cpu_initial_reset() etc and then examined in the
reset method, but doing it this way seems cleaner.
The motivation for this change is that this is the last caller
of the legacy device_class_set_parent_reset() function, and
removing that will let us clean up some glue code that we added
for the transition to three-phase reset.

QAPI's 'prefix' feature can make the connection between enumeration
type and its constants less than obvious. It's best used with
restraint.
CpuS390Entitlement has a 'prefix' to change the generated enumeration
constants' prefix from CPU_S390_ENTITLEMENT to S390_CPU_ENTITLEMENT.
Rename the type to S390CpuEntitlement, so that 'prefix' is not needed.
Likewise change CpuS390Polarization to S390CpuPolarization, and
CpuS390State to S390CpuState.

CpuModelInfo is used both as command argument and in command
returns.
Its @deprecated-props array does not make any sense in arguments,
and is silently ignored. We actually want it only as return value
of query-cpu-model-expansion.
Move it from CpuModelInfo to CpuModelExpansionType, and document
its dependence on expansion type property.
This was identified late during review [1] and we have to fix it up
while it's not part of an official QEMU release yet.

Avoid a race condition with munmap in another thread.
For access_memset and access_memmove, manage the value
within the helper. For uses of access_{get,set}_byte,
manage the value across the for loops.
