convert to_pid_to_str

2014-02-19  Tom Tromey  <tromey@redhat.com>

	* target-delegates.c: Rebuild.
	* target.c (target_pid_to_str): Unconditionally delegate.
	(init_dummy_target): Don't initialize to_pid_to_str.
	(default_pid_to_str): Rename from dummy_pid_to_str.
	* target.h (struct target_ops) <to_pid_to_str>: Use
	TARGET_DEFAULT_FUNC.
