Summary:                    memory leak in zt_new()
Description: 
zt_new() calls ast_channel_alloc() with cid_num, cid_name but later in
zt_new(), the following code is executed, which overwrites cid-stuff in the
"tmp-channel":

#ifdef PRI_ANI
	tmp->cid.cid_num = ast_strdup(i->cid_num);
	tmp->cid.cid_name = ast_strdup(i->cid_name);
	if (!ast_strlen_zero(i->cid_ani))
		tmp->cid.cid_ani = ast_strdup(i->cid_ani);
	else	
		tmp->cid.cid_ani = ast_strdup(i->cid_num);
#else
	tmp->cid.cid_num = ast_strdup(i->cid_num);
	tmp->cid.cid_ani = ast_strdup(i->cid_num);
	tmp->cid.cid_name = ast_strdup(i->cid_name);
#endif

In ast_channel_alloc() cid_num and cid_name are already set and a memory
leak occurs when the ast_strdup() above is executed.
