  1. cpu: Introduce CPUClass::gdb_core_xml_file for GDB_CORE_XML 

    Replace the GDB_CORE_XML define in gdbstub.c with a CPUClass field.
Use first_cpu for qSupported and qXfer:features:read: for now.
Add a stub for xml_builtin.

  4. gdbstub: Replace GET_REG*() macros with gdb_get_reg*() functions 

    This avoids polluting the global namespace with a non-prefixed macro and
makes it obvious in the call sites that we return.

Semi-automatic conversion using, e.g.,
 sed -i 's/GET_REGL(/return gdb_get_regl(mem_buf, /g' target-*/gdbstub.c
followed by manual tweaking for sparc's GET_REGA() and Coding Style.

  19. 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.

  22. 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.

  26. cpu: Introduce CPUClass::memory_rw_debug() for target_memory_rw_debug() 

    Make inline target_memory_rw_debug() always available and change its
argument to CPUState. Let it check if CPUClass::memory_rw_debug provides
a specialized callback and fall back to cpu_memory_rw_debug() otherwise.

The only overriding implementation is for 32-bit sparc.

This prepares for changing GDBState::g_cpu to CPUState.

  28. 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().

Prepares for changing cpu_memory_rw_debug() argument to CPUState.
