* ppc-linux-nat.c: Update copyright.
	(fetch_register, store_register): Add tid parameter, don't compute
	tid here.
	(fetch_ppc_registers, store_ppc_registers): Add tid
	parameter. Pass it along to callees.
	(fetch_inferior_registers, store_inferior_registers): Compute tid
	here, and pass it to calleed functions.
	(fill_gregset, supply_fpregset): Clean up formatting.
