* infptrace.c: Split out define of PT_KILL; Sequent defines PT_KILL

	but not the others.
	* symm-tdep.c: Remove exec_file_command.
	[_SEQUENT_] (ptx_coff_regno_to_gdb, register_addr): New functions.
	A few miscellaneous cleanups.
	* symm-nat.c: Renamed from symm-xdep.c.
	* All symmetry dependent files: Many changes.
