ISSUE:       1961
TITLE:       RDB$procedures generator overflow
DESCRIPTION:
  Total number of created procedures is set by 'TOTAL_PROCEDURES_COUNT' variable.

  In order to reduce time:
    * FW is changed OFF
    * test uses LOCAL connection protocol
  Confirmed bug on 2.0.6.13266, got:
    Statement failed, SQLCODE = -607
    unsuccessful metadata update
    -STORE RDB$PROCEDURES failed
    -arithmetic exception, numeric overflow, or string truncation
    -At trigger 'RDB$TRIGGER_28'
  (value of gen_id(rdb$procedures,0) is 32768 when this error raises)
JIRA:        CORE-1544
FBTEST:      bugs.core_1544
NOTES:
[27.05.2022] pzotov
  Re-implemented for work in firebird-qa suite. 
  Checked on: 3.0.8.33535, 4.0.1.2692, 5.0.0.497
