cpu: Move current_tb field to CPUState
Explictly NULL it on CPU reset since it was located before breakpoints. Change vapic_report_tpr_access() argument to CPUState. This also resolves the use of void* for cpu.h independence. Change vAPIC patch_instruction() argument to X86CPU. Signed-off-by: Andreas Färber <afaerber@suse.de>
