utils: apply Inoussa patch Unicode utils (issue #0022909):
  This patch fixes some memory overwrites that were causing the helpers crash.
  It introduces the generation of the little endian and big endian files 
  regardless of the host endianess.
  The patch also adds some new test cases. The cldrparser program now accepts a
  "-t" switch to execute the test suite.
