ID:          issue-5859
ISSUE:       5859
TITLE:       System function RDB$ROLE_IN_USE cannot take long role names
DESCRIPTION:
  Test creates several roles and grants them to user.
  Role #1 is common ascii string without spaces.
  Role #2 is ascii string with spaces, all character are written in UPPERCASE.
  Role #3 is ascii string with spaces, all character are written in lowercase.

  After make connection to database using role #3 we have to check that this role
  indeed was applied to connection and that rdb$role_in_use *does* return this role name also.
  See also: github.com/FirebirdSQL/firebird/commit/61b4bf0d276884a0ba0f2edef3b41fa2c58c87ee
  Comments there:
     - roleStr.upper();
     + //roleStr.upper();		// sorry - but this breaks role names containing lower case letters


  ::: NB CAUTION ::: TEMPLY DEFERRED :::
  We also have to check cases when role contains NON-ASCII characters but currently this is impossible.
  Exception like:
  ===
   Statement failed, SQLSTATE = 22001
   arithmetic exception, numeric overflow, or string truncation
   -string right truncation
   -expected length 63, actual 79
  ===
  - is raised when non-ascii role contains only ~40 *characters* and connection charset = UTF8.
