Kill pthread_ops_hack

	* target.h (struct target_ops): Make to_attach, to_detach,
	to_create_inferior and to_mourn_inferior accept a pointer
    	to struct target_ops.
	(target_attach, target_create_inferior, target_create_inferior):
	Convert from macros to function.  Find the right target to
	invoke a method of.
	(find_default_attach, find_default_create_inferior): New parameter
	ops.
	* corefile.c (core_file_command): Pass target to to_detach.
	* corelow.c (core_detach): Add 'ops' parameter.
	* fork-child.c (fork_inferior): Return the pid.  Allow
	init_trace_fun to be NULL.
	* inf-ptrace (ptrace_ops_hack): Remove.
	(inf_ptrace_him): Remove, moving all logic into....
	(inf_ptrace_create_inferior): ... here.  Push the target
	passed as parameter.
	(inf_ptrace_mourn_inferior, inf_ptrace_attach, inf_ptrace_detach):
	Push/pop target passed as parameter, no ptrace_ops_hack.
	(inf_ptrace_target): Don't remember result.
	* inferior.h (fork_inferior): Adjust prototype.
	* linux-nat.c (linux_nat_create_inferior, linux_nat_attach)
	(linux_nat_detach, linux_nat_mourn_inferior): New parameter ops.
	Pass it to linux_ops target.
	* linux-thread-db.c (thread_db_detach, thread_db_mourn_inferior):
	New parameter ops. Pass it to the target beneath.
	* remote.c (remote_mourn, extended_remote_mourn, remote_detach)
	(extended_remote_create_inferior): New parameter ops. Pass it
	further.
	* target.c (debug_to_attach, debug_to_detach)
	(debug_to_mourn_inferior): New parameter ops.
	(target_create_inferior): New.
	(update_current_target): Do not inherit to_attach, to_detach,
	to_create_inferiour, to_mourn_inferior.  Do not default
	to_detach and to_mourn_inferior.
	(target_detach): Find the right target to use.
	(target_mourn_inferior): New.
	(find_default_attach, find_default_create_inferior): New parameter
	ops.  Pass the found target when calling its method.
	(init_dummy_target): Provide fallback definition of to_detach.
	(target_attach): New.
	(debug_to_attach, debug_to_detach, debug_to_create_inferior)
	(debug_to_mourn_inferiour): New parameter ops.
