delay the setting of the ldap variable until we've ensured we were

	* addressbook/backend/pas/pas-backend-ldap.c
	(pas_backend_ldap_build_all_cards_list): delay the setting of the
	ldap variable until we've ensured we were connected.  Also, set
	the search limit to LDAP_MAX_SEARCH_RESPONSES (we'll eventually
	want a user setting here i assume.)
	(pas_backend_ldap_search): same here, and also send back lists of
	CARDS_PER_VIEW_NOTIFICATION length in each
	pas_book_view_notify_add call.  also, don't call ber_free if there
	was a decoding error, since the ldap library frees it for us.
