ISSUE:       6092
TITLE:       Not user friendly output of gstat at encrypted database
DESCRIPTION:
    We create new database ('tmp_core_5831.fdb') and try to encrypt it usng IBSurgeon Demo Encryption package
    ( https://ib-aid.com/download-demo-firebird-encryption-plugin/ ; https://ib-aid.com/download/crypt/CryptTest.zip )
    License file plugins\\dbcrypt.conf with unlimited expiration was provided by IBSurgeon to Firebird Foundation (FF).
    This file was preliminary stored in FF Test machine.
    Test assumes that this file and all neccessary libraries already were stored into FB_HOME and %FB_HOME%\\plugins.

    After test database will be created, we try to encrypt it using 'alter database encrypt with <plugin_name> ...' command
    (where <plugin_name> = dbcrypt - name of .dll in FB_HOME\\plugins\\ folder that implements encryption).
    Then we allow engine to complete this job - take delay about 1..2 seconds BEFORE detach from database.

    After this we detach from DB, run 'gstat -h' and filter its attributes and messages from 'Variable header' section.
    In the output of gstat we check that its 'tail' will look like this:
    ===
        Attributes	force write, encrypted, plugin DBCRYPT
        Crypt checksum:	MUB2NTJqchh9RshmP6xFAiIc2iI=
        Key hash: ask88tfWbinvC6b1JvS9Mfuh47c=
        Encryption key name: RED
    ===
    (concrete values for checksum and hash will be ignored - see 'substitutions' section).

    Finally, we change this temp DB statee to full shutdown in order to have 100% ability to drop this file.

    Checked on:
        40sS, build 4.0.0.1487: OK, 3.347s.
        40Cs, build 4.0.0.1487: OK, 3.506s.
        30sS, build 3.0.5.33120: OK, 2.697s.
        30Cs, build 3.0.5.33120: OK, 3.054s.

    15.04.2021. Adapted for run both on Windows and Linux. Checked on:
      Windows: 4.0.0.2416
      Linux:   4.0.0.2416

#  # There is bug in FB driver which leads this command to fail with 'token unknown' message
#  # The reason is that execute_immediate() silently set client dialect = 0 and any encryption statement
#  # can not be used for such value of client dialect.
#  # One need to to use only cursor_obj.execute() for encryption!
