cpu: Introduce CPUClass::synchronize_from_tb() for cpu_pc_from_tb()

Where no extra implementation is needed, fall back to CPUClass::set_pc().

linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-user

The functions cpu_clone_regs() and cpu_set_tls() are not purely CPU
related -- they are specific to the TLS ABI for a a particular OS.
Move them into the linux-user/ tree where they belong....

cpu: Move halted and interrupt_request fields to CPUState

Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before
breakpoints.

Pass PowerPCCPU to kvmppc_handle_halt().

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...

target-m68k: Introduce QOM realizefn for M68kCPU

Introduce realizefn and set realized = true in cpu_m68k_init().

Split off GDB registration to a new m68k_cpu_init_gdb() so that it can
be called from the realizefn.

m68k: use caller supplied CPUState for interrupt related stuff

It would be cleaner to move the function to helper.c, but there are
a few dependencies between do_interrupt() and other functions....
