[commit] Delete target_post_wait

[Andrew Cagney <cagney at gnu dot org>]

It turns out that this method is only set to an empty function, this 
zaps the dead method and all references.

committed,
Andrew

2004-09-29  Andrew Cagney  <cagney@gnu.org>

	* target.h (struct target_ops): Delete field to_post_wait.
	(target_post_wait): Delete macro.
	(child_post_wait): Delete declaration.
	* target.c (update_current_target, update_current_target)
	(debug_to_post_wait, setup_target_debug): Delete functions and
	references.
	* infttrace.c (ptrace_wait): Delete call to target_post_wait.
	* inftarg.c (child_post_wait): Delete.
	(init_child_ops): Do not set to_post_wait.
	* infptrace.c (ptrace_wait): Delete call to target_post_wait.
	* inf-ptrace.c (inf_ptrace_wait): Delete call to target_post_wait.
	* inf-child.c (inf_child_post_wait): Delete.
	(inf_child_target): Do not set to_post_wait.
	* inf-ptrace.c (inf_ptrace_post_wait): Delete.
	(inf_ptrace_target): Do not set to_post_wait.
