ISSUE:       5747
TITLE:       Trace duplicates asci_char(13) in its output (Windows only)
DESCRIPTION:
  We launch trace and create connect to DB with statement line 'select 1 from rdb$database'.
  Trace log should contain several lines related to connection, transaction and statement.
  These lines should be separated by standard Windows PAIR of characters: CR + NL.
  Count of these chars should be equal (ideally; actually 1st line in trace has EOL = single NL
  rather than pair CR+NL).
  We then open trace log as binary file and read all its content into dict of Counter type,
  thus we can get number of occurences for each character, including CR and NL.
  Finally, we compare number of occurences of CR and NL. Difference has to be no more than 1.
