cpu: Partially revert "cpu: Change qemu_init_vcpu() argument to CPUState"

Commit c643bed99 moved qemu_init_vcpu() calls to common CPUState code.
This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed".

The reason for the failure is that CPUClass::kvm_fd is not yet...

cpu: Introduce CPUClass::gdb_{read,write}_register()

Completes migration of target-specific code to new target-*/gdbstub.c.

cpu: Introduce CPUState::gdb_num_regs and CPUClass::gdb_num_core_regs

CPUState::gdb_num_regs replaces num_g_regs.
CPUClass::gdb_num_core_regs replaces NUM_CORE_REGS.

Allows building gdb_register_coprocessor() for xtensa, too.

As a side effect this should fix coprocessor register numbering for SMP....

target-xtensa: Introduce XtensaCPU subclasses

Register a CPU type per core registered. Save the XtensaConfig in
XtensaCPUClass and copy it from there to CPUXtensaState, to avoid
touching every env->config access for now.

Prepares for storing per-class GDB register count....

cpu: Turn cpu_get_phys_page_debug() into a CPUClass hook

Change breakpoint_invalidate() argument to CPUState alongside.

Since all targets now assign a softmmu-only field, we can drop helpers
cpu_class_set_{do_unassigned_access,vmsd}() and device_class_set_vmsd()....

cpu: Introduce CPUClass::set_pc() for gdb_set_cpu_pc()

This moves setting the Program Counter from gdbstub into target code.
Use vaddr type as upper-bound replacement for target_ulong.

cpu: Change qemu_init_vcpu() argument to CPUState

This allows to move the call into CPUState's realizefn.
Therefore move the stub into libqemustub.a.

cpu: Turn cpu_dump_{state,statistics}() into CPUState hooks

Make cpustats monitor command available unconditionally.

Prepares for changing kvm_handle_internal_error() and kvm_cpu_exec()
arguments to CPUState.

cpu: Replace do_interrupt() by CPUClass::do_interrupt method

This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.

It will also allow to override the interrupt handling for certain CPU...

cpu: Add CPUArchState pointer to CPUState

The target-specific ENV_GET_CPU() macros have allowed us to navigate
from CPUArchState to CPUState. The reverse direction was not supported.
Avoid introducing CPU_GET_ENV() macros by initializing an untyped
pointer that is initialized in derived instance_init functions....

target-xtensa: Move TCG initialization to XtensaCPU initfn

Combine this with breakpoint handler registration, guarding both with
tcg_enabled() to suppress also TCG init for qtest. Rename the handler to
xtensa_breakpoint_handler() since it needs to become global....

target-xtensa: Introduce QOM realizefn for XtensaCPU

Introduce realizefn and set realized = true in cpu_xtensa_init().

target-xtensa: Mark as unmigratable

There was no CPU_SAVE_VERSION defined, so neither "cpu_common" VMState
nor cpu_{save,load}() were registered. Their implementation was no-op.
Therefore there is no backwards compatibility to keep, so mark XtensaCPU
as unmigratable at device level....

target-xtensa: implement ATOMCTL SR

ATOMCTL SR controls s32c1i opcode behavior depending on targeted memory
type. See ISA, 4.3.12.4 for details.

target-xtensa: implement CACHEATTR SR

In XEA1, the Options for Memory Protection and Translation and the
corresponding TLB management instructions are not available. Instead,
functionality similar to the Region Protection Option is available
through the cache attribute register. See ISA, A.2.14 for details....

target-xtensa: Let cpu_xtensa_init() return XtensaCPU

Make the include paths for cpu-qom.h consistent to allow using XtensaCPU
in cpu.h.

Turn cpu_init macro into a static inline function returning
CPUXtensaState for backwards compatibility.

To avoid moving reset_mmu() and dependencies, make it non-static.
