Shared matadata cache. Regression since 6.0.0.1771: one may to invoke private packaged procedure from outer code

[Pavel Zotov]

Consider script:

==============

set bail on;
set echo on;
shell if exist r:\temp\tmp4test.fdb del r:\temp\tmp4test.fdb;
create database 'localhost:r:\temp\tmp4test.fdb' user sysdba password 'masterkey';

set term ^;
create or alter package pg_temp as
begin
end
^
recreate package body pg_temp as
begin
    procedure sp_get_top_secret returns(id int, f01 boolean) as
    begin
        for
            select rand()*1000, rand() < 0.5
            from rdb$types
            rows 5
        into
            id, f01
        do
            suspend;
    end
end
^
set term ;^

select * from pg_temp.sp_get_top_secret;
commit;

==============

NOTE: package header is EMPTY.

On 3.x ... 5.x and up to 6.0.0.1465-3bbe725 it will show:

...

select * from pg_temp.sp_get_top_secret;
Statement failed, SQLSTATE = 42000
Procedure "SP_GET_TOP_SECRET" is private to package "PUBLIC"."PG_TEMP"

Since 6.0.0.1771-f73321c procedure SP_GET_TOP_SECRET can be called w/o error and shows data:

select * from pg_temp.sp_get_top_secret;

          ID     F01
============ =======
         857 <false>
         880 <false>
         111 <false>
         266 <false>
         353 <false>
