ISSUE:       4822
TITLE:       ISQL command SHOW USERS display only me
DESCRIPTION:
NOTES:
[29.07.2016]
  instead of issuing SHOW USERS which has unstable output (can be changed multiple times!)
  it was decided to replace it with SQL query which actually is done by this command.
  This query can be easily found in trace when we run SHOW USERS.
  Also, we limit output with only those users who is enumerated here thus one may do not warry about
  another user logins which could left in securitiN.fdb after some test failed.
[29.03.2018] changed user names, replaced count of SYSDBA attachments with literal 1.
