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.

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.

Since commit 878096eeb2 (cpu: Turn
cpu_dump_{state,statistics}() into CPUState hooks) CPUArchState is no
longer needed.
Add documentation and make the functions available through qemu/log.h
outside NEED_CPU_H to allow use in qom/cpu.c. Moving them to qom/cpu.h
was not yet possible due to convoluted include paths, so that some
devices grow an implicit and unneeded dependency on qom/cpu.h for now.

Sun4c and Sun4d architectures and related CPUs are not fully implemented

Likewise, a few CPUs (Cypress, Ross etc) are only half implemented.

Avoid introducing CPU_GET_ENV() macros by initializing an untyped
